Controller is a network device that serves as a gateway between wired and wireless networks and provides command-and-control over Access Points (APs) within an Aruba dependant wireless network. ArubaOS 6.3 is the underlying operating system of the Mobility Controller, which is available in modular chassis or network appliance models: a) Aruba 7000 and 6000 Series. The Aruba 7240, 7220, 7210 and 6000 with M3 blades are designed for corporate headquarters and large campus deployments. b) Aruba 3000 Series. The Aruba 3200, 3400 and 3600 are designed for small, medium and large enterprises. c) Aruba 600 Series. The Aruba 620 and 650 are designed for branch offices and similar deployments. 2 This Security Target (ST) defines the Mobility Controller (7240, 7220, 7210, 6000, 3600, 3400, 3200, 650, 620) with ArubaOS 6.3 Target of Evaluation (TOE) for the purposes of Common Criteria (CC) evaluation. 3 Whilst the Aruba Networks Mobility Controller offers a wide range of wireless, wired and remote networking features, the TOE is constrained to the following security features: a) Secure communication with remote administrators, authentication servers and audit servers b) Secure management including authentication, verifiable updates and auditing c) Self-verification of integrity and operation 4 For a precise statement of the scope of incorporated security features, refer to section 2.4. NOTE: The Wireless and Access Point capabilities of these devices were not tested under this evaluation as those aspects are not within the scope of the NDPP. 5 Identification Table 1: Evaluation identifiers Target of Evaluation Aruba Networks Mobility Controller (7240, 7220, 7210, 6000, 3600, 3400, 3200, 650, 620) with ArubaOS 6.3 Software Version: 6.3.1.5-FIPS Security Target Aruba Networks Mobility Controller (7240, 7220, 7210, 6000, 3600, 3400, 3200, 650, 620) with ArubaOS 6.3 Security Target, v1.12 1.2 Conformance Claims 6 This ST supports the following conformance claims: a) CC version 3.1 release 3 b) CC Part 2 extended c) CC Part 3 conformant Aruba Networks Security Target Page 6 of 67 d) U.S. Government Approved Protection Profile - Security Requirements for Network Devices , v1.1 (herein referred to as NDPP) 1.3 Terminology Table 2: Terminology Term Definition ACL Access Control List AP Access Point ARM Adaptive Radio Management CC Common Criteria CLI Command Line Interface CSP Critical Security Parameter EAL Evaluation Assurance Level KAT Known Answer Test NDPP U.S. Government Approved Protection Profile – Security Requirements for Network Devices , v1.1 NIST National Institute of Standards and Technology NTP Network Time Protocol OSP Organizational Security Policy PP Protection Profile RAP Remote Access Point RF Radio Frequency ST Security Target TOE Target of Evaluation TSF TOE Security Functionality WebUI Web User Interface 1.4 References [USER] ArubaOS 6.3.x User Guide, Ref 0511497-00 Aruba Networks Security Target Page 7 of 67 [CLI] ArubaOS 6.3.x Command Line Interface, Ref 0511500-00 [SYSLOG] ArubaOS 6.3.x Syslog Messages Guide, Ref 0511324-01 [MIB] ArubaOS 6.3 MIB Reference Guide, Ref 0511323-01 [FIPS] Aruba 600/3000/6000/7200 FIPS 140-2 Security Policy Aruba Networks Security Target Page 8 of 67 2 TOE Description 2.1 Type 7 The TOE is a network device. 8 In the CC evaluated configuration, the TOE must be configured to operate in the FIPS 140-2 Approved mode of operation. In FIPS-Approved mode, weak protocols and algorithms are disabled. Please reference the appropriate FIPS 140-2 Security Policy documents for each controller and access point for more details at http://csrc.nist.gov/groups/STM/cmvp/index.html. 2.2 TOE Architecture 9 At a high level, Aruba Mobility Controllers are hardware appliances consisting of a multicore network processor, Ethernet interfaces, and required supporting circuitry and power supplies enclosed in a metal chassis. The software running on the Mobility Controller is called ArubaOS, which consists of two main components, both implemented on multiple cores within a single network processor: a) Control Plane (CP)—implements functions which can be handled at lower speeds such as Mobility Controller system management (CLI and Web GUI), user authentication (e.g. 802.1X, RADIUS, LDAP), Internet Key Exchange (IKE), auditing/logging (syslog), Wireless IDS (WIDS), and termination of protocols operating at the system level (e.g. SSH, TLS, NTP, etc.). The Control Plane runs the Linux operating system along with various user-space applications (described below). b) Data Plane (DP)—implements functions that must be handled at high speeds such as high-speed switching functions (forwarding, VLAN tagging/enforcement, bridging), termination of 802.11 associations/sessions, tunnel termination (GRE, IPsec), deep packet inspection functions, and cryptographic acceleration. The Data Plane runs a lightweight, proprietary real-time OS which is known as “SOS” (an acronym whose definition is no longer known). 10 The Control Plane and Data Plane are inseparable. Administrators install the software by loading a single file, identified as “ArubaOS”. Internally, the Mobility Controller unpacks the ArubaOS software image into its various components. A given ArubaOS software image has a single version number, and includes all software components necessary to operate both mobility controllers and APs. 11 The CP runs the Linux OS, along with various custom user-space applications which provide the following CP functions: a) Monitors and manages critical system resources, including processes, memory, and flash b) Manages system configuration and licensing c) Manages an internal database used to store licenses, user authentication information, etc. d) Provides network anomaly detection, hardware monitoring, mobility management, wireless management, and radio frequency management services e) Provides a Command Line Interface (CLI) Aruba Networks Security Target Page 9 of 67 f) Provides a web-based (HTTPS/TLS) management UI for the mobility controller g) Provides various WLAN station and AP management functions h) Provides authentication services for the system management interfaces (CLI, web GUI) as well as for WLAN users i) Provides IPsec key management services for APs and connections with other Aruba mobility controllers (Note: IPsec for APs, VPN users and other mobility controllers is not within the scope of evaluation) j) Provides network time protocol service for APs, point to point tunnelling protocol services for users, layer 2 tunnelling protocol services for users, SSH services for incoming management connections, SNMP client/agent services, and protocol independent multicast (routing) services for the controller k) Provides syslog services by sending logs to the operating environment. 12 The Linux OS running on the CP is a version 2.6.32 kernel. Linux is a soft real-time, multi-threaded operating system that supports memory protection between processes. Only Aruba provided interfaces are used, and the CLI is a restricted command set. Administrators do not have access to the Linux command shell or operating system. 13 The DP is further subdivided into two subcomponents: Fast Path (FP) and Slow1 Path (SP). The FP implements high-speed packet forwarding based on various proprietary tables and sends the packets to SP. The SP manages (create, delete, and age entries) all DP tables such as user, station, tunnel, route, ARP cache, session, bridge, VLAN2, and port. The SP also performs deep packet inspection and cryptographic processing. 14 The data plane is implemented on a multi-core network processor. There is a lightweight, Aruba-proprietary OS running on the network processor called SOS. SOS contains an Ethernet driver, a serial driver, a logging facility, semaphore support, and a crypto driver. This OS is not a general purpose operating system. In the Aruba 6000 with M3 controller card, an FPGA is also used to control and monitor the switch fabric, Ethernet interface hardware, and provide security functionality such as filtering. 15 The DP and CP run on different hardware platforms but the security functionality remains the same, regardless of the model. The differences in the platforms are in the processors, memory capacity, physical interfaces, FPGA implementation, etc., and are based on performance and scalability requirements. 2.3 Usage 16 The TOE is generally deployed as a gateway between wired and wireless networks that performs command-and-control within an Aruba dependent wireless network architecture consisting of one or more Aruba mobility controllers and multiple Aruba wireless APs. In this architecture, Aruba split the traditional functions of an all-in-one 1 The entire DP (including both FP and SP elements) is a high-speed packet processor, so the SP designation should be understood to be relative in terms of speed. 2 A VLAN has the same attributes as a physical LAN, but it allows for end devices to be grouped together even if they are not located on the same network switch. Network reconfiguration can be done through the Aruba software instead of physically relocating devices. Aruba Networks Security Target Page 10 of 67 wireless access point between the controller and the AP. A simple TOE deployment is depicted in Figure 1. Figure 1: TOE usage scenario 17 There are many combinations of deployment scenarios, ranging from branch office environments in which the mobility controller and access point are combined (Aruba 600 Series) to campus deployments with multiple redundant mobility controllers. 18 The non-security functionality provided by a mobility controller goes beyond managing dependants APs, and includes: a) Performing Layer 2 switching and Layer 3 routing b) Terminating Internet-based remote access points c) Providing advanced Radio Frequency (RF) services with Adaptive Radio Management (ARM) and spectrum analysis d) Providing location services and RF coverage “heat maps” of the deployment e) Providing self-contained management by way of a master/local hierarchy with one controller f) Pushing configuration to other mobility controllers to reduce administrative overhead g) Delivering AP software updates automatically when the mobility controller is upgraded 2.4 Security Functions 19 The TOE provides the following security functions: a) Protected communications. The TOE protects the following communication flows: i) WebUI. Communication with the administrative web user interface (WebUI) is protected using TLS/HTTPS. ii) CLI. Remote administration via the Command Line Interface (CLI) is protected using SSHv2. iii) Syslog. Syslog messages are protected using IPSec. iv) Radius. Radius authentication messages are protected using IPSec. Aruba Networks Security Target Page 11 of 67 b) Verifiable updates. Updates are digitally signed and verified upon installation utilizing digital signatures. c) System monitoring. The TOE maintains an audit log of administrative and security relevant events. Logs can optionally be delivered to a Syslog server. d) Secure administration. The TOE provides administration interfaces for configuration and monitoring. The TOE authenticates administrators and implements session timeouts. e) Residual information clearing. The TOE ensures that network packets sent from the TOE do not include data "left over" from the processing of previous network information. f) Self-test. The TOE performs both power-up and conditional self-tests to verify correct and secure operation. g) Firewall. The TOE performs stateful packet filtering. Wireless clients connecting through APs are placed into user-roles. Stateful packet filter policies are applied to these user-roles to allow fine grained control over wireless traffic. Note: Firewall functionality is not within the scope of this evaluation. 2.5 Physical Scope 20 The TOE comprises the ArubaOS 6.3 software and the chassis and appliance models listed in Table 3. 21 ArubaOS 6.3 consists of a base software package with add-on software modules that can be activated by installing the appropriate licenses.

FCS_SSH_EXT.1.7 The TSF shall ensure that diffie-hellman-group14-sha1 is the only allowed key exchange method used for the SSH protocol. 5.3.3 User Data Protection (FDP) FDP_RIP.2 Full Residual Information Protection FDP_RIP.2.1 The TSF shall ensure that any previous information content of a resource is made unavailable upon the deallocation of the resource from all objects. 5.3.4 Identification and Authentication (FIA) FIA_PMG_EXT.1 Password Management FIA_PMG_EXT.1.1 The TSF shall provide the following password management capabilities for administrative passwords: 1. Passwords shall be able to be composed of any combination of upper and lower case letters, numbers, and the following special characters: “!”, “@”, “#”, “$”, “%”, “^”, “&”, “*”, “_”, “<”, “>”, “{“, “}”, “[“, “]”, “:”, “.”, “|”, “+”. “~”, “,”, “ ` ”; 2. Minimum password length shall settable by the Security Administrator, and support passwords of 15 characters or greater; 5.3.5 User Identification and Authentication (FIA_UIA) FIA_UIA_EXT.1 User Identification and Authentication FIA_UIA_EXT.1.1 The TSF shall allow the following actions prior to requiring the non-TOE entity to initiate the identification and authentication process:  Display the warning banner in accordance with FTA_TAB.1;  no other actions Aruba Networks Security Target Page 28 of 67 FIA_UIA_EXT.1.2 The TSF shall require each administrative user to be successfully identified and authenticated before allowing any other TSF-mediated actions on behalf of that administrative user. FIA_UAU_EXT.2 Extended: Password-based Authentication Mechanism FIA_UAU_EXT.2.1 The TSF shall provide a local password-based authentication mechanism, Radius username/password authentication and Public Key authentication] to perform administrative user authentication. FIA_UAU.7 Protected Authentication Feedback FIA_UAU.7.1 The TSF shall provide only obscured feedback to the administrative user while the authentication is in progress at the local console. Application Note: “Obscured feedback” implies the TSF does not produce a visible display of any authentication data entered by a user (such as the echoing of a password), although an obscured indication of progress may be provided (such as an asterisk for each character). It also implies that the TSF does not return any information during the authentication process to the user that may provide any indication of the authentication data. 5.3.6 Security Management (FMT) FMT_MTD.1 Management of TSF Data (for general TSF data) FMT_MTD.1.1 The TSF shall restrict the ability to manage the TSF data to the Security Administrators.

Application Note: The intent of the requirement is that an administrator is unable to read or view the identified keys (stored or ephemeral) through “normal” interfaces. While it is understood that the administrator could directly read memory to view these keys, do so is not a trivial task and may require substantial work on the part of an administrator. Since the administrator is considered a trusted agent, it is assumed they would not endeavor in such an activity. FPT_APW_EXT.1 Extended: Protection of Administrator Passwords FPT_APW_EXT.1.1 The TSF shall store passwords in non-plaintext form. FPT_APW_EXT.1.2 The TSF shall prevent the reading of plaintext passwords. Application Note: The intent of the requirement is that raw password authentication data are not stored in the clear, and that no user or administrator is able to read the plaintext password through “normal” interfaces. An all-powerful administrator of course could directly read memory to capture a password but is trusted not to do so. FPT_STM.1 Reliable Time Stamps FPT_STM.1.1 The TSF shall be able to provide reliable time stamps for its own use. FPT_TUD_EXT.1 Extended: Trusted Update FPT_TUD_EXT.1.1 The TSF shall provide security administrators the ability to query the current version of the TOE firmware/software.

FTA_SSL.4 User-initiated Termination FTA_SSL.4.1 The TSF shall allow Administrator-initiated termination of the Administrator’s own interactive session. FTA_TAB.1 Default TOE Access Banners FTA_TAB.1.1 Refinement: Before establishing an administrative user session the TSF shall display a Security Administrator-specified advisory notice and consent warning message regarding use of the TOE. 5.3.9 Trusted Path/Channels (FTP) FTP_ITC.1 Inter-TSF trusted channel FTP_ITC.1.1 Refinement: The TSF shall use IPsec to provide a trusted communication channel between itself and authorized IT entities supporting the following capabilities: audit server, authentication server that is logically distinct from other communication channels and provides assured identification of its end points and protection of the channel data from disclosure and detection of modification of the channel data. FTP_ITC.1.2 The TSF shall permit the TSF, or the authorized IT entities to initiate communication via the trusted channel. FTP_ ITC.1.3 The TSF shall initiate communication via the trusted channel for Syslog messages and RADIUS authentication. FTP_TRP.1 Trusted Path FTP_TRP.1.1 Refinement: The TSF shall use SSH, TLS/HTTPS to provide a trusted communication path between itself and remote administrators that is Aruba Networks Security Target Page 31 of 67 logically distinct from other communication paths and provides assured identification of its end points and protection of the communicated data from disclosure and detection of modification of the communicated data. FTP_TRP.1.2 Refinement: The TSF shall permit remote administrators to initiate communication via the trusted path. FTP_TRP.1.3 The TSF shall require the use of the trusted path for initial administrator authentication and all remote administration actions. 5.4 Assurance Requirements 36 The TOE security assurance requirements, summarized in Table 12, are drawn from the NDPP commensurate with EAL1. In accordance with the NDPP, these are supplemented with additional assurance activities as identified at Annex A: NDPP Assurance Activities. Table 12: Assurance Requirements Assurance Class Components Description Development ADV_FSP.1 Basic Functional Specification Guidance Documents AGD_OPE.1 Operational User Guidance AGD_PRE.1 Preparative User Guidance Tests ATE_IND.1 Independent Testing - conformance Vulnerability Assessment AVA_VAN.1 Vulnerability Analysis Life Cycle Support ALC_CMC.1 Labelling of the TOE ALC_CMS.1 TOE CM Coverage Aruba Networks Security Target Page 32 of 67 6 TOE Summary Specification 6.1 Security Functions 6.1.1 Protected Communications Related SFRs: FCS_CKM.1(1), FCS_CKM.1(2), FCS_CKM.1(3), FCS_CKM_EXT.4, FCS_COP.1(1), FCS_COP.1(2), FCS_COP.1(3), FCS_COP.1(4), FCS_RBG_EXT.1(1), FCS_RBG_EXT.1(2), FPT_SKP_EXT.1, FTP_ITC.1, FTP_TRP.1, FCS_IPSEC_EXT.1, FCS_SSH_EXT.1, FCS_TLS_EXT.1, FCS_HTTPS_EXT.1 37 The TOE protects the following communication flows: a) WebUI. Remote administration via the WebUI is protected using TLS/HTTPS.  TLS/HTTPS is enabled by default. b) CLI. Remote administration via the Command Line Interface (CLI) is protected using SSHv2.  SSHv2 is enabled by default c) Syslog. Syslog messages are protected using IPSec.  To set up site-to-site IPsec refer to [USER] page 288 “Working with Site-to-Site VPNs”. Configure the IP address of the syslog server as the destination network. d) RADIUS. RADIUS authentication messages are protected using IPSec.  Same configuration as syslog – set up site-to-site IPsec, and configure the IP address of the RADIUS server as the destination network. 38 Note: The TOE must be operated in a FIPS 140-2 approved mode of operation to ensure that only approved cryptographic operations and algorithms are supported. To enable FIPS mode, use the command “fips enable” from CLI config mode, as documented in the FIPS 140-2 Security Policy. Operation in non-FIPS mode is not part of this evaluation. 39 Note: RBG services are not configurable. 40 Note: By default, the TOE enables the FTP service for the purpose of providing software images to wireless access points. This service should be disabled when operating in an approved mode of operation. To disable the FTP service, use the CLI command “firewall disable-ftp-server”. 6.1.1.1 TLS\HTTPS Related SFRs: FCS_CKM.1(1), FCS_CKM_EXT.4, FCS_COP.1(1), FCS_COP.1(2), FCS_COP.1(3), FCS_COP.1(4), FCS_RBG_EXT.1(1), FPT_SKP_EXT.1, FTP_TRP.1, FCS_TLS_EXT.1, FCS_HTTPS_EXT.1 41 The TOE implements a web server that provides the WebUI, The web server is configured by default to use HTTPS. The TOE’s implementation of HTTPS uses TLS 1.2 (RFC 5246) without extensions, supporting the ciphersuites identified in FCS_TLS_EXT.1. The available ciphersuites are not configurable. If the web server has been configured to use an RSA certificate, the TOE will use RSA-based TLS ciphersuites. If the web server has been configured to use an ECDSA certificate, the TOE will use ECDSA-based TLS ciphersuites. Aruba Networks Security Target Page 33 of 67 42 The TOE may be configured to support username/password authentication, client certificate authentication or both. 43 Refer to [USER] Chapter 35 – Management Access. “Configuring Certificate Authentication for WebUI Access” for more information. 6.1.1.2 IPSec Related SFRs: FCS_CKM.1(2), FCS_CKM_EXT.4, FCS_COP.1(1), FCS_COP.1(2), FCS_COP.1(3), FCS_COP.1(4), FCS_COP.1(5), FCS_RBG_EXT.1(2), FPT_SKP_EXT.1, FTP_ITC.1, FCS_IPSEC_EXT.1 44 IPsec is documented in [USER] Chapter 18 “Virtual Private Networks” 45 IPSec can be configured to secure communication with a Syslog server or Radius server. 46 The TOE’s IPSec implementation has the following characteristics: a) The algorithms specified at FCS_IPSEC_EXT.1.1 are supported. In addition, AES-CBC-192 and 3DES are also supported by the TOE. These algorithms have not been evaluated during the Common Criteria evaluation and must not be used. b) IKEv1 and IKEv2 are supported. c) Only tunnel mode is supported. IPsec transport mode is not supported. d) The “confidentiality only" ESP mode is disabled in the TOE. This behaviour has been hard-coded by excluding the related configuration option from the administrative interfaces (WebUI and CLI). e) Aggressive mode is not used for IKEv1 Phase 1 exchanges - only main mode is available.  Aggressive mode must be disabled in order to ensure it is not used. This is documented in [CLI] and is performed using the command “crypto-local isakmp disable-aggressive-mode”. f) Lifetimes for IKEv1 SAs (both Phase 1 and Phase 2) are established during configuration of the IKE policies by specifying the number of seconds or the number of kb for the SA lifetime.  Setting the lifetime in number of seconds is documented in [USER} Chapter 18. Volume (traffic) based lifetimes are configured using “crypto dynamic-map set security-association lifetime kilobytes” as documented in [CLI]. g) The TOE supports the DH groups listed at FCS_IPSEC_EXT.1.5. One DH group is configured per IKE policy. IKE policies are incorporated into IPSec maps. IPsec maps are given a priority for peer negotiation. Negotiation requests for security associations will try to match the highest-priority map first. If that map does not match, the negotiation request will continue down the list to the next-highest priority map until a match is made. h) All IKE protocols implement DH Groups 14 (2048-bit MODP), 19 (256-bit Random ECP), and 20 (384-bit Random ECP. DH group 2 (1024-bit MODP) is also supported by the TOE – it was not evaluated during the Common Criteria evaluation and must not be used. i) IKE peer authentication is performed with either an IKE pre-shared key or digital certificates. IKE policies may be configured to use RSA (rDSA) or ECDSA authentication when using digital certificates. FCS_COP.1(2) Aruba Networks Security Target Page 34 of 67 requires RSA key sizes of 2048 bits or greater. The TOE supports an RSA key size of 1024 bits in addition to 2048 bits. The administrator must not load an RSA X.509 certificate with a key size smaller than 2048 bits when operating in the Common Criteria evaluated configuration. j) Pre-shared keys are manually entered during IKE policy configuration. The pre-shared key is used in combination with an agreed DH secret key and an exchanged nonce to generate session keys (SKEYs) which are used to authenticate the two peers to each other as well as to encrypt subsequent IKE exchanges. k) Pre-shared keys conform to the character and length requirements at FCS_IPSEC_EXT.1.8. l) Only HMAC-SHA-1/256/384 are supported, with key and digest sizes of 160, 256, and 384 bits respectively. The TOE prevents configuration of MD5 while operating in FIPS mode. m) Random number generator services for IPsec are provided automatically by the TOE and do not require administrator configuration. 6.1.1.3 SSH Related SFRs: FCS_CKM.1(3), FCS_CKM_EXT.4, FCS_COP.1(1), FCS_COP.1(3), FCS_COP.1(4), FCS_RBG_EXT.1(1), FPT_SKP_EXT.1, FTP_TRP.1, FCS_SSH_EXT.1 47 The CLI can be accessed from an SSHv2 enabled client. The TOE’s SSH implementation has the following characteristics: a) SSHv2 is supported b) Public key and password authentication is supported  [USER] Chapter 35, “Enabling Public Key Authentication for SSH Access” provides more information. c) The following algorithms are implemented: SSH_RSA for public keys, AES- CBC-128 and AES-CBC-256 for encryption, HMAC-SHA1 and HMAC-SHA1- 96 for integrity. Note: The encryption and integrity algorithms used are not configurable by the administrator. d) Packets greater than 32,768 bytes in an SSH transport connection are dropped. e) All key exchanges for SSH are performed using DH group 14. This behavior is hard-coded into the TOE. f) No optional protocol characteristics are implemented. 6.1.2 Verifiable Updates Related SFRs: FPT_TUD_EXT.1, FCS_COP.1(2), FCS_COP.1(3) 48 Administrators can update the TOE executable code using image files manually downloaded from the Aruba support portal. The administrator may perform an update from either the WebUI or CLI.  Upgrade instructions are documented in the release notes for each software release, which will be posted in the same directory as the image file on the support portal. Aruba Networks Security Target Page 35 of 67 49 A SHA-256 hash of each update image is digitally signed using Aruba’s code signing certificate (RSA 2048 bit). When an update is initiated, the TOE verifies the digital signature with a stored certificate (stored in Boot ROM). 50 Upon successful verification, the TOE boots using the new image. Should verification fail, the TOE will enter into an error state. The TOE’s error state will allow direct console access only, where an administrator can change to a new file partition or TFTP a new image and re-boot. 6.1.3 System Monitoring Related SFRs: FAU_GEN.1, FAU_GEN.2, FAU_STG_EXT.1, FPT_STM.1 51 The TOE maintains an audit log of administrative and security relevant events. Logs can optionally be delivered to a Syslog server. The administrator can configure the TOE to protect Syslog messages using IPSec as described in section 6.1.1.2. Further detail regarding Syslog and audit messages is provided in the guidance document: ArubaOS 6.3 Syslog Messages, Ref 0510838-01.  [USER] Chapter 35, Management Access->Configuring Logging provides more details on configuring to use Syslog. Select all Categories and all Subcategories. Set the logging level to “Warning” for all Categories and Subcategories to generate all of the security event logs as defined in FAU_GEN.1 Table 15.  If Syslog has been enabled, all audit logs are simultaneously written to both the local audit log and the syslog server. 52 Note: The command “show audit-trail” as documented in [CLI] is used to show a log of all administrative actions. By default, only commands which change system behaviour are logged. By setting the configuration parameter “audit-trail all”, all commands will be logged including commands which do not alter system behaviour. 53 The TOE uses an internal system clock to provide reliable timestamps for audit logs. The system clock can be set manually or by configuring the TOE to use a Network Time Protocol (NTP) server to synchronize its system clock with a central time source. If connectivity to the NTP server is lost, the TOE continues to maintain time using the internal system clock and re-synchronizes with the NTP server once connectivity is re-established.  [USER] Chapter 35, Management Access->Setting the System Clock provides instructions on setting the system clock. 54 In the event that a TOE network interface is overwhelmed by traffic the TOE will drop packets. An administrator can examine interface counters (using the ‘show interface’ command) to determine if the TOE has dropped packets due to being overwhelmed by traffic. 55 The TOE’s local audit log consists of three files (for each audit category) that are 31,768 bytes each. The log files are filled consecutively. Once the last file is full, the TOE will begin overwriting the first log file. The log files may only be access by an Authorized Administrator – described in the following section. 6.1.4 Secure Administration Related SFRs: FIA_UIA_EXT.1, FIA_UIA_EXT.2, FIA_PMG_EXT.1, FIA_UAU.7, FMT_MTD.1, FMT_SMF.1, FMT_SMR.2, FPT_APW_EXT.1, FTA_SSL_EXT.1, FTA_SSL.3, FTA_SSL.4, FTA_TAB.1, FPT_STM.1 56 Initial configuration of the TOE is performed using a question-and-answer dialog presented through the console port after the TOE is powered on for the first time, or Aruba Networks Security Target Page 36 of 67 when the configuration of the TOE has been erased using the “write erase” command. While in this default state, no TOE services are available and the TOE does not forward traffic through network interfaces. During the initial configuration dialog, an administrative username and password is established. Once initial configuration has been completed, the TOE reboots into a secure state. 57 The TOE provides two interfaces for administration: WebUI and CLI. The WebUI is accessed via TLS/HTTPS. The CLI is accessed via SSH or direct console. For both TLS/HTTPS and SSH the TOE can be configured to use username/password only, public key authentication only or both username/password and public key authentication. Direct console to the CLI only supports username/password.  [USER] Chapter 35 “Management Access” has documentation for setting these options. 58 The TOE can be configured to use a Radius server for username/password authentication. The same user repository (either local or Radius) is used from both WebUI and CLI access. Passwords stored locally are encrypted using the TOE’s KEK and cannot be viewed via any normal interface. Password complexity rules are enforced by the TOE (see FIA_PMG_EXT.1), and passwords are obscured during entry.  [USER] Chapter 35 – “Enabling RADIUS Server Authentication” and “Implementing a Specific Password Management Policy” provide more instruction on how to configure passwords.  [USER] Ch. 35 - Implementing a Specific Management Password Policy describes setting minimum password length. 59 A successful logon takes place when a recognized username/password combination is provided and/or a recognized X.509 client certificate is presented by the administrator’s web browser or SSH client. 60 No administrative functions are accessible prior to administrator log-in. Before establishing an administrative user session the TOE displays an administrator specified advisory notice and consent warning message regarding use of the TOE.  Banner configuration is documented in the [CLI] under “banner motd” 61 The TOE associates users with their assigned role upon successful authentication. The “Authorized Administrator” role defined by the NDPP equates to the “root” role implemented by the TOE. 62 For both the WebUI and CLI, administrative sessions will terminate according to an administrator defined period of inactivity. The system clock as described in paragraph 52 is used to time the period of inactivity. Administrators can terminate their own session by logging out.  [USER] Chapter 35, “Setting an Administrator Session Timeout” provides instructions on setting session timeouts. The system clock time is also used for timestamps in audit log records. [USER} Chapter 35 - Setting the System Clock describes how the system clock can be changed. 6.1.5 Residual Information Clearing Related SFRs: FDP_RIP.2 63 The TOE ensures that network packets sent from the TOE do not include data "left over" from the processing of previous network information. Aruba Networks Security Target Page 37 of 67 64 The memory buffers used in packet processing are sanitized subsequent to each packet being processed. Buffers are made logically unavailable by overwriting the buffer headers with zeroes. 6.1.6 Self Test Related SFRs: FPT_TST_EXT.1 65 The TOE performs both power-up and conditional self-tests to verify correct and secure operation. In the event that any self-test fails, the TOE will enter an error state, log the error, and reboot automatically. Failure of self-tests requires return to manufacturer. Relevant log messages are identified in the following supplements: a) Aruba 3000, 6000/M3 and Dell W-3000, W-6000M3 Controllers with ArubaOS FIPS Firmware Non-Proprietary Security Policy FIPS 140-2 Level 2 Release Supplement.

Ref 0510888-02. 66 The following test are performed: a) ArubaOS OpenSSL Module: i) AES Known Answer Tests (KAT) ii) Triple-DES KAT iii) RNG KAT iv) RSA KAT v) ECDSA (sign/verify) vi) SHA (SHA1, SHA256 and SHA384) KAT vii) HMAC (HMAC-SHA1, HMAC-SHA256 and HMAC-SHA384) KAT b) ArubaOS Cryptographic Module i) AES KAT ii) Triple-DES KAT iii) SHA (SHA1, SHA256, SHA384 and SHA512) KAT iv) HMAC (HMAC-SHA1, HMAC-SHA256, HMAC-SHA384 and HMAC- SHA512) KAT v) RSA (sign/verify) vi) ECDSA (sign/verify) vii) FIPS 186-2 RNG KAT c) ArubaOS Uboot BootLoader Module i) Firmware Integrity Test: RSA 2048-bit Signature Validation d) Aruba Hardware Known Answer Tests: i) AES KAT ii) AES-CCM KAT iii) AES-GCM KAT iv) Triple DES KAT Aruba Networks Security Target Page 38 of 67 v) HMAC (HMAC-SHA1, HMAC-SHA256, HMAC-SHA384 and HMAC- SHA512) KAT 67 The following Conditional Self-tests are performed by the TOE: a) Continuous Random Number Generator Test. This test is run upon generation of random data by the switch’s random number generators to detect failure to a constant value. The module stores the first random number for subsequent comparison, and the module compares the value of the new random number with the random number generated in the previous round and enters an error state if the comparison is successful. b) Bypass test. Ensures that the system has not been placed into a mode of operation where cryptographic operations have been bypassed, without the explicit configuration of the cryptographic officer. To conduct the test, a SHA1 hash of the configuration file is calculated and compared to the last known good hash of the configuration file. If the hashes match, the test is passed. Otherwise, the test fails (indicating possible tampering with the configuration file) and the system is halted. c) RSA Pairwise Consistency test. When the TOE generates a public and private key pair, it carries out pair-wise consistency tests for both encryption and digital signing. The test involves encrypting a randomly-generated message with the public key. If the output is equal to the input message, the test fails. The encrypted message is then decrypted using the private key and if the output is not equal to the original message, the test fails. The same random message is then signed using the private key and then verified with the public key. If the verification fails, the test fails. d) ECDSA Pairwise Consistency test. See above RSA pairwise consistency test description. e) Firmware Load Test. This test is identical to the Uboot BootLoader Module Firmware Integrity Test, except that it is performed at the time a new software image is loaded onto the system. Instead of being performed by the BootLoader, the test is performed by the ArubaOS operating system. If the test fails, the newly loaded software image will not be copied into the image partition, and instead will be deleted. Refer to section 6.1.2. 68 Known-answer tests (KAT) involve operating the cryptographic algorithm on data for which the correct output is already known and comparing the calculated output with the previously generated output (the known answer). If the calculated output does not equal the known answer, the known-answer test shall fail. 69 The above tests are sufficient to demonstrate that the TSF is operating correctly by verifying the integrity of the TSF and the correct operation of cryptographic components. 6.2 Cryptography 70 This section incorporates additional detail regarding cryptography required by the NDPP. 71 The TOE uses cryptographic functions provided by FIPS 140-2 validated modules:  CMVP Certificate #1727  CMVP Certificate #1865  FIPS Algorithm certificates issued: AES #2689, #2680, #2677.

The CAVP list for each algorithm can be found at http://csrc.nist.gov/groups/STM/cavp/validation.html. 6.2.1 Standards Conformance – Key Generation / Establishment 6.2.1.1 RSA 72 The TOE utilizes RSA for key establishment within HTTPS/TLS and IPSec. The TOE’s implementation of RSA conforms to NIST Special Publication 800-56B, “Recommendation for Pair-Wise Key Establishment Schemes Using Integer Factorization Cryptography”. 73 Sections 5 through 9 of NIST Special Publication 800-56B are applicable to the TOE. The TOE conforms to all shall, shall-not, should and should-not statements. There are no TOE-specific implementation extensions. 6.2.1.2 Diffie-Hellman 74 The TOE utilizes Diffie-Hellman within IPSec and SSH. The TOE’s implementation of Diffie-Hellman conforms to NIST Special Publication 800-56A, “Recommendation for Pair-Wise Key Establishment Schemes Using Discrete Logarithm Cryptography”. 75 Diffie-Hellman relevant subsections of sections 5 through 8 of NIST Special Publication 800-56A are applicable to the TOE. The TOE conforms to all shall, shall- not, should and should-not statements. There are no TOE-specific implementation extensions. 6.2.1.3 ECDSA 76 The TOE utilizes ECDSA within IPSec. The TOE’s implementation of ECDSA conforms to NIST Special Publication 800-56A, “Recommendation for Pair-Wise Key Establishment Schemes Using Discrete Logarithm Cryptography”. 77 Elliptic Curve Cryptography (ECC) relevant subsections of sections 5 through 8 of NIST Special Publication 800-56A are applicable to the TOE. The TOE conforms to all shall, shall-not, should and should-not statements. There are no TOE-specific implementation extensions. 6.2.2 Critical Security Parameters 78 Table 13 below identifies all secret and private keys and Critical Security Parameters (CSPs), the related zeroization procedures and whether any interface is available to view the plaintext key. 79 Note that the plaintext keys identified in Table 13 are not able to be viewed via a ‘normal user interface’, that is, no user interface is provided by design and therefore the keys are protected. Per the NDPP FPT_SKP_EXT.1 application note, it is understood that the administrator could directly read memory to view these keys, [however to] do so is not a trivial task and may require substantial work on the part of an administrator. Since the administrator is considered a trusted agent, it is assumed they would not endeavor in such an activity. Shared secrets entered by a user are only viewable during entry. 80 Table 13: CSPs Aruba Networks Security Target Page 40 of 67 # Name CSPs type Generation Storage and Zeroization Use 1 Key Encryption Key (KEK) Triple-DES 168-bit key Hardcoded during manufacturing Stored in Flash.

Two management interfaces can be used for this purpose:  SSHv2 CLI The Crypto Officer can use the CLI to perform non-security-sensitive and security-sensitive monitoring and configuration. The CLI can be accessed remotely by using the SSHv2 secured management session over the Ethernet ports or locally over the serial port. In FIPS mode, the serial port is disabled.  Web Interface The Crypto Officer can use the Web Interface as an alternative to the CLI. The Web Interface provides a highly intuitive, graphical interface for a comprehensive set of controller management tools. The Web Interface can be accessed from a TLS-enabled Web browser using HTTPS (HTTP with Secure Socket Layer) on logical port 4343. See the table below for descriptions of the services available to the Crypto Officer role. Numbers in the “CSP Access” column refers to the Critical Security Parameters table above.

As identified in section 2.1, the TOE is a network device, consistent with the TOE type identified by the NDPP. b) Security problem definition. As shown in section 3, the threats, OSPs and assumptions are identical to those of the NDPP. c) Security objectives. As shown in section 4, the security objectives are identical to those of the NDPP. d) Security requirements. As shown in section 5, the security requirements are reproduced from the NDPP. No additional requirements have been specified. In accordance with NDPP section 3.1, footnote 1, FPT_ITT.1 has been excluded as the TOE is not distributed. 7.2 Security Objectives Rationale 83 All security objectives are drawn directly from the NDPP. 7.3 Security Requirements Rationale 84 All security requirements are drawn directly from the NDPP. 85 In accordance with NDPP section 3.1, footnote 1, FPT_ITT.1 has been excluded as the TOE is not distributed. 7.4 TOE Summary Specification Rationale 86 Table 15 provides a coverage mapping showing that all SFRs are mapped to the security functions described in the TSS.

As these are spread throughout the NDPP document, the table below provides a consolidated reference. # NDPP Source Requirement Assurance Family 1. FAU_GEN. 1 The evaluator shall check the administrative guide and ensure that it lists all of the auditable events and provides a format for audit records. Each audit record format type must be covered, along with a brief description of each field. The evaluator shall check to make sure that every audit event type mandated by the PP is described and that the description of the fields contains the information required in FAU_GEN1.2, and the additional information specified in Table 1 of the NDPP. AGD_OPE 2. FAU_GEN. 1 The evaluator shall also make a determination of the administrative actions that are relevant in the context of this PP. The evaluator shall examine the administrative guide and make a determination of which administrative commands, including subcommands, scripts, and configuration files, are related to the configuration (including enabling or disabling) of the mechanisms implemented in the TOE that are necessary to enforce the requirements specified in the PP. The evaluator shall document the methodology or approach taken while determining which actions in the administrative guide are security relevant with respect to this PP. The evaluator may perform this activity as part of the activities associated with ensuring the AGD_OPE guidance satisfies the requirements. AGD_OPE 3. FAU_GEN. 1 The evaluator shall test the TOE’s ability to correctly generate audit records by having the TOE generate audit records for the events listed in table 1 and administrative actions. This should include all instances of an event--for instance, if there are several different I&A mechanisms for a system, the FIA_UIA_EXT.1 events must be generated for each mechanism. The evaluator shall test that audit records are generated for the establishment and termination of a channel for each of the cryptographic protocols contained in the ST. If HTTPS is implemented, the test demonstrating the establishment and termination of a TLS session can be combined with the test for an HTTPS session. For administrative actions, the evaluator shall test that each action determined by the evaluator above to be security relevant in the context of this PP is auditable. When verifying the test results, the evaluator shall ensure the audit records generated during testing match the format specified in the administrative guide, and that the fields in each audit record have the proper entries. Note that the testing here can be accomplished in conjunction with the testing of the security mechanisms directly. For example, testing performed to ensure that the administrative guidance provided is correct verifies that AGD_OPE.1 is satisfied and should address the invocation of the administrative actions that are needed to verify the audit records are generated as expected. ATE_IND 4. FAU_STG_ EXT.1 For both types of TOEs (those that act as an audit server and those that send data to an external audit server), there is some amount of local storage. The evaluator shall examine the TSS to ensure it describes the amount of audit data that are stored locally; what happens when the local audit data store is full; and ASE_TSS AGD_OPE Aruba Networks Security Target Page 52 of 67 # NDPP Source Requirement Assurance Family how these records are protected against unauthorized access. The evaluator shall also examine the operational guidance to determine that it describes the relationship between the local audit data and the audit data that are sent to the audit log server (for TOEs that are not acting as an audit log server). For example, when an audit event is generated, is it simultaneously sent to the external server and the local store, or is the local store used as a buffer and “cleared” periodically by sending the data to the audit server. 5. FAU_STG_ EXT.1.1 TOE acts as audit server The evaluator shall examine the TSS to ensure it describes the connection supported from non-TOE entities to send the audit data to the TOE, and how the trusted channel is provided. Testing of the trusted channel mechanism will be performed as specified in the associated assurance activities for the particular trusted channel mechanism. The evaluator shall also examine the operational guidance to ensure it describes how to establish the trusted channel with the TOE, as well as describe any requirements for other IT entities to connect and send audit data to the TOE (particular audit server protocol, version of the protocol required, etc.), as well as configuration of the TOE needed to communicate with other IT entities. The evaluator shall perform the following test for this requirement: Test 1: The evaluator shall establish a session between an external IT entity and the TOE according to the configuration guidance provided. The evaluator shall then examine the traffic that passes between the IT entity and the TOE during several activities of the evaluator’s choice designed to generate audit data to be transferred to the TOE. The evaluator shall observe that these data are not able to be viewed in the clear during this transfer, and that they are successfully received by the TOE. The evaluator shall perform this test for each protocol selected in the second selection. ASE_TSS ATE_IND AGD_OPE 6. FAU_STG_ EXT.1 TOE is not an audit server The evaluator shall examine the TSS to ensure it describes the means by which the audit data are transferred to the external audit server, and how the trusted channel is provided. Testing of the trusted channel mechanism will be performed as specified in the associated assurance activities for the particular trusted channel mechanism. The evaluator shall also examine the operational guidance to ensure it describes how to establish the trusted channel to the audit server, as well as describe any requirements on the audit server (particular audit server protocol, version of the protocol required, etc.), as well as configuration of the TOE needed to communicate with the audit server. The evaluator shall perform the following test for this requirement: Test 1: The evaluator shall establish a session between the TOE and the audit server according to the configuration guidance provided. The evaluator shall then examine the traffic that passes between the audit server and the TOE during several activities of the evaluator’s choice designed to generate audit data to be transferred to the audit server. The evaluator shall observe that these data are not able to be viewed in the clear during this transfer, and that they are successfully received by the audit server. The evaluator shall record the particular software (name, version) used on the audit server during testing. ASE_TSS ATE_IND AGD_OPE 7. FCS_CKM. The evaluator shall use the key pair generation portions of "The FIPS 186-3 ATE_IND Aruba Networks Security Target Page 53 of 67 # NDPP Source Requirement Assurance Family 1 Digital Signature Algorithm Validation System (DSA2VS)", "The FIPS 186-3 Elliptic Curve Digital Signature Algorithm Validation System (ECDSA2VS)", and "The RSA Validation System (RSA2VS)" as a guide in testing the requirement above, depending on the selection performed by the ST author. This will require that the evaluator have a trusted reference implementation of the algorithms that can produce test vectors that are verifiable during the test. In order to show that the TSF complies with 800-56A and/or 800-56B, depending on the selections made, the evaluator shall ensure that the TSS contains the following information:  The TSS shall list all sections of the appropriate 800-56 standard(s) to which the TOE complies.  For each applicable section listed in the TSS, for all statements that are not "shall" (that is, "shall not", "should", and "should not"), if the TOE implements such options it shall be described in the TSS. If the included functionality is indicated as "shall not" or "should not" in the standard, the TSS shall provide a rationale for why this will not adversely affect the security policy implemented by the TOE;  For each applicable section of 800-56A and 800-56B (as selected), any omission of functionality related to "shall" or “should” statements shall be described; Any TOE-specific extensions, processing that is not included in the documents, or alternative implementations allowed by the documents that may impact the security requirements the TOE is to enforce shall be described ASE_TSS 8. FCS_CKM _EXT.4 The evaluator shall check to ensure the TSS describes each of the secret keys (keys used for symmetric encryption), private keys, and CSPs used to generate key; when they are zeroized (for example, immediately after use, on system shutdown, etc.); and the type of zeroization procedure that is performed (overwrite with zeroes, overwrite three times with random pattern, etc.). If different types of memory are used to store the materials to be protected, the evaluator shall check to ensure that the TSS describes the zeroization procedure in terms of the memory in which the data are stored (for example, "secret keys stored on flash are zeroized by overwriting once with zeroes, while secret keys stored on the internal hard drive are zeroized by overwriting three times with a random pattern that is changed before each write"). ASE_TSS 9. FCS_COP. 1(1) The evaluator shall use tests appropriate to the modes selected in the above requirement from "The Advanced Encryption Standard Algorithm Validation Suite (AESAVS)", "The XTS-AES Validation System (XTSVS)", The CMAC Validation System (CMACVS)", "The Counter with Cipher Block Chaining Message Authentication Code (CCM) Validation System (CCMVS)", and "The Galois/Counter Mode (GCM) and GMAC Validation System (GCMVS)" (these documents are available from http://csrc.nist.gov/groups/STM/cavp/index.html) as a guide in testing the requirement above. This will require that the evaluator have a reference implementation of the algorithms known to be good that can produce test vectors that are verifiable during the test. ATE_IND 10. FCS_COP. 1(2) The evaluator shall use the signature generation and signature verification portions of "The Digital Signature Algorithm Validation System” (DSAVS or DSA2VS), "The Elliptic Curve Digital Signature Algorithm Validation System” ATE_IND Aruba Networks Security Target Page 54 of 67 # NDPP Source Requirement Assurance Family (ECDSAVS or ECDSA2VS), and "The RSA Validation System” (RSAVS) as a guide in testing the requirement above. The Validation System used shall comply with the conformance standard identified in the ST (i.e., FIPS PUB 186-2 or FIPS PUB 186-3). This will require that the evaluator have a reference implementation of the algorithms known to be good that can produce test vectors that are verifiable during the test. 11. FCS_COP. 1(3) The evaluator shall use "The Keyed-Hash Message Authentication Code (HMAC) Validation System (HMACVS)" as a guide in testing the requirement above. This will require that the evaluator have a reference implementation of the algorithms known to be good that can produce test vectors that are verifiable during the test. ATE_IND 12. FCS_RBG _EXT.1 Documentation shall be produced—and the evaluator shall perform the activities—in accordance with NDPP Annex D, Entropy Documentation and Assessment. The evaluator shall also perform the following tests, depending on the standard to which the RBG conforms. Implementations Conforming to FIPS 140-2, Annex C The reference for the tests contained in this section is The Random Number Generator Validation System (RNGVS) [RNGVS]. The evaluator shall conduct the following two tests. Note that the "expected values" are produced by a reference implementation of the algorithm that is known to be correct. Proof of correctness is left to each Scheme. The evaluator shall perform a Variable Seed Test. The evaluator shall provide a set of 128 (Seed, DT) pairs to the TSF RBG function, each 128 bits. The evaluator shall also provide a key (of the length appropriate to the AES algorithm) that is constant for all 128 (Seed, DT) pairs. The DT value is incremented by 1 for each set. The seed values shall have no repeats within the set. The evaluator ensures that the values returned by the TSF match the expected values. The evaluator shall perform a Monte Carlo Test. For this test, they supply an initial Seed and DT value to the TSF RBG function; each of these is 128 bits. The evaluator shall also provide a key (of the length appropriate to the AES algorithm) that is constant throughout the test. The evaluator then invokes the TSF RBG 10,000 times, with the DT value being incremented by 1 on each iteration, and the new seed for the subsequent iteration produced as specified in NIST-Recommended Random Number Generator Based on ANSI X9.31 Appendix A.2.4 Using the 3-Key Triple DES and AES Algorithms, Section 3. The evaluator ensures that the 10,000 th value produced matches the expected value. Entropy Document ATE_IND 13. FCS_RBG _EXT.1 Implementations Conforming to NIST Special Publication 800-90 The evaluator shall perform 15 trials for the RBG implementation. If the RBG is configurable, the evaluator shall perform 15 trials for each configuration. The evaluator shall also confirm that the operational guidance contains appropriate instructions for configuring the RBG functionality. If the RBG has prediction resistance enabled, each trial consists of (1) instantiate drbg, (2) generate the first block of random bits (3) generate a second block of random bits (4) uninstantiate. The evaluator verifies that the second block of random bits is the expected value. The evaluator shall generate eight input Entropy Document ATE_IND Aruba Networks Security Target Page 55 of 67 # NDPP Source Requirement Assurance Family values for each trial. The first is a count (0 – 14). The next three are entropy input, nonce, and personalization string for the instantiate operation. The next two are additional input and entropy input for the first call to generate. The final two are additional input and entropy input for the second call to generate. These values are randomly generated. “generate one block of random bits” means to generate random bits with number of returned bits equal to the Output Block Length (as defined in NIST SP 800-90). If the RBG does not have prediction resistance, each trial consists of (1) instantiate drbg, (2) generate the first block of random bits (3) reseed, (4) generate a second block of random bits (5) uninstantiate. The evaluator verifies that the second block of random bits is the expected value. The evaluator shall generate eight input values for each trial. The first is a count (0 – 14). The next three are entropy input, nonce, and personalization string for the instantiate operation. The fifth value is additional input to the first call to generate. The sixth and seventh are additional input and entropy input to the call to reseed. The final value is additional input to the second generate call. The following paragraphs contain more information on some of the input values to be generated/selected by the evaluator. Entropy input: the length of the entropy input value must equal the seed length. Nonce: If a nonce is supported (CTR_DRBG with no df does not use a nonce), the nonce bit length is one-half the seed length. Personalization string: The length of the personalization string must be <= seed length. If the implementation only supports one personalization string length, then the same length can be used for both values. If more than one string length is support, the evaluator shall use personalization strings of two different lengths. If the implementation does not use a personalization string, no value needs to be supplied. Additional input: the additional input bit lengths have the same defaults and restrictions as the personalization string lengths. 14. FCS_HTTP S_EXT.1 The evaluator shall check the TSS to ensure that it is clear on how HTTPS uses TLS to establish an administrative session, focusing on any client authentication required by the TLS protocol vs. Security administrator authentication which may be done at a different level of the processing stack. Testing for this activity is done as part of the TLS testing; this may result in additional testing if the TLS tests are done at the TLS protocol level. ASE_TSS 15. FCS_TLS_ EXT.1 The evaluator shall check the description of the implementation of this protocol in the TSS to ensure that optional characteristics (e.g., extensions supported, client authentication supported) are specified, and the ciphersuites supported are specified as well. The evaluator shall check the TSS to ensure that the ciphersuites specified are identical to those listed for this component. The evaluator shall also check the operational guidance to ensure that it contains instructions on configuring the TOE so that TLS conforms to the description in the TSS (for instance, the set of ciphersuites advertised by the TOE may have to be restricted to meet the requirements). The evaluator shall also perform the following test: Test 1: The evaluator shall establish a TLS connection using each of the ciphersuites specified by the requirement. This connection may be established ASE_TSS ATE_IND Aruba Networks Security Target Page 56 of 67 # NDPP Source Requirement Assurance Family as part of the establishment of a higher-level protocol, e.g., as part of a HTTPS session. It is sufficient to observe (on the wire) the successful negotiation of a ciphersuite to satisfy the intent of the test; it is not necessary to examine the characteristics of the encrypted traffic in an attempt to discern the ciphersuite being used (for example, that the cryptographic algorithm is 128-bit AES and not 256-bit AES). 16. FCS_IPSE C_EXT.1.2 The evaluator shall examine the TSS to verify that it describes how "confidentiality only" ESP mode is disabled. The evaluator shall also examine the operational guidance to determine that it describes any configuration necessary to ensure that "confidentiality only" mode is disabled, and that an advisory is present indicating that tunnel mode is the preferred ESP mode since it protects the entire packet. The evaluator shall examine the TSS to ensure that, in the description of the IPsec protocol supported by the TOE, it states that aggressive mode is not used for IKEv1 Phase 1 exchanges, and that only main mode is used. If this requires configuration of the TOE prior to its operation, the evaluator shall check the operational guidance to ensure that instructions for this configuration are contained within that guidance. The evaluator shall also perform the following tests: Test 1: The evaluator shall configure the TOE as indicated in the operational guidance, and attempt to establish a connection using an IKEv1 Phase 1 connection in aggressive mode. This attempt should fail. The evaluator should then show that main mode exchanges are supported. Test 2: The evaluator shall configure the TOE as indicated in the operational guidance, and attempt to establish a connection using ESP in "confidentiality only" mode. This attempt should fail. The evaluator shall then establish a connection using ESP in confidentiality and integrity mode. ASE_TSS ATE_IND 17. FCS_IPSE C_EXT.1.3 The evaluator checks to ensure that the TSS describes how lifetimes for IKEv1 SAs (both Phase 1 and Phase 2) are established. If they are configurable, then the evaluator verifies that the appropriate instructions for configuring these values are included in the operational guidance. The evaluator also performs the following test: Test 1: The evaluator shall construct a test where a Phase 1 SA is established and attempted to be maintained for more than 24 hours before it is renegotiated. The evaluator shall observe that this SA is closed or renegotiated in 24 hours or less. If such an action requires that the TOE be configured in a specific way, the evaluator shall implement tests demonstrating that the configuration capability of the TOE works as documented in the operational guidance. Test 2: The evaluator shall perform a test similar to Test 1 for Phase 2 SAs, except that the lifetime will be 8 hours instead of 24. ASE_TSS ATE_IND 18. FCS_IPSE C_EXT.1.4 The evaluator checks to ensure that the TSS describes how lifetimes for IKEv1 Phase 2 SAs—with respect to the amount of traffic that is allowed to flow using a given SA--are established. If the value is configurable, then the evaluator verifies that the appropriate instructions for configuring these values are included in the operational guidance. The evaluator also performs the following test: Test 1: The evaluator shall construct a test where a Phase 2 SA is established ASE_TSS ATE_IND Aruba Networks Security Target Page 57 of 67 # NDPP Source Requirement Assurance Family and attempted to be maintained while more data than is specified in the above assignment flows over the connection. The evaluator shall observe that this SA is closed or renegotiated before the amount of data specified is exceeded. If such an action requires that the TOE be configured in a specific way, the evaluator shall implement tests demonstrating that the configuration capability of the TOE works as documented in the operational guidance. 19. FCS_IPSE C_EXT.1.5 The evaluator shall check to ensure that the DH groups specified in the requirement are listed as being supported in the TSS. If there is more than one DH group supported, the evaluator checks to ensure the TSS describes how a particular DH group is specified/negotiated with a peer. The evaluator shall also perform the following test: Test 1: For each supported DH group, the evaluator shall test to ensure that all IKE protocols can be successfully completed using that particular DH group. ASE_TSS ATE_IND 20. FCS_IPSE C_EXT.1.6 The evaluator shall check that the TSS contains a description of the IKE peer authentication process used by the TOE, and that this description covers the use of the signature algorithm or algorithms specified in the requirement. The evaluator shall also perform the following test: Test 1: For each supported signature algorithm, the evaluator shall test that peer authentication using that algorithm can be successfully achieved. ASE_TSS ATE_IND 21. FCS_IPSE C_EXT.1.7 The evaluator shall check to ensure that the TSS describes how pre-shared keys are established and used in authentication of IPsec connections. The evaluator shall check that the operational guidance describes how pre-shared keys are to be generated and established for a TOE. The description in the TSS and the operational guidance shall also indicate how pre-shared key establishment is accomplished for both TOEs that can generate a pre-shared key as well as TOEs that simply use a pre-shared key. The evaluator shall also perform the following test: Test 1: The evaluator shall generate a pre-shared key and use it, as indicated in the operational guidance, to establish an IPsec connection between two peers. If the TOE supports generation of the pre-shared key, the evaluator shall ensure that establishment of the key is carried out for an instance of the TOE generating the key as well as an instance of the TOE merely taking in and using the key. ASE_TSS ATE_IND 22. FCS_IPSE C_EXT.1.8 The evaluator shall check the operational guidance to ensure that it describes the generation of preshared keys, including guidance on generating strong keys and the allowed character set. The evaluator shall check that this guidance does not limit the pre-shared key in a way that would not satisfy the requirement. It should be noted that while the administrator (in contravention to the operational guidance) can choose a key that does not conform to the requirement, there is no requirement that the TOE check the key to ensure that it meets the rules specified in this component. However, should the administrator choose to create a password that conforms to the rules above (and the operational guidance); the TOE should not prohibit such a choice. The evaluator shall also perform the following test; this may be combined with Test 1 for FCS_IPSEC_EXT.1.7: Test 1: The evaluator shall generate a pre-shared key that is 22 characters long that meets the composition requirements above. The evaluator shall then use AGD_OPE ATE_IND Aruba Networks Security Target Page 58 of 67 # NDPP Source Requirement Assurance Family this key to successfully establish an IPsec connection. While the evaluator is not required to test that all of the special characters or lengths listed in the requirement are supported, it is required that they justify the subset of those characters chosen for testing, if a subset is indeed used. 23. FCS_SSH_ EXT.1.2 The evaluator shall check to ensure that the TSS contains a description of the public key algorithms that are acceptable for use for authentication, that this list conforms to FCS_SSH_EXT.1.5, and ensure that password-based authentication methods are also allowed. The evaluator shall also perform the following tests: Test 1: The evaluator shall, for each public key algorithm supported, show that the TOE supports the use of that public key algorithm to authenticate a user connection. Any configuration activities required to support this test shall be performed according to instructions in the operational guidance. Test 2: Using the operational guidance, the evaluator shall configure the TOE to accept password-based authentication, and demonstrate that a user can be successfully authenticated to the TOE over SSH using a password as an authenticator. ASE_TSS ATE_IND 24. FCS_SSH_ EXT.1.3 The evaluator shall check that the TSS describes how “large packets” in terms of RFC 4253 are detected and handled. The evaluator shall also perform the following test: Test 1: The evaluator shall demonstrate that if the TOE receives a packet larger than that specified in this component, that packet is dropped. ASE_TSS ATE_IND 25. FCS_SSH_ EXT.1.4 The evaluator shall check the description of the implementation of this protocol in the TSS to ensure that optional characteristics are specified, and the encryption algorithms supported are specified as well. The evaluator shall check the TSS to ensure that the encryption algorithms specified are identical to those listed for this component. The evaluator shall also check the operational guidance to ensure that it contains instructions on configuring the TOE so that SSH conforms to the description in the TSS (for instance, the set of algorithms advertised by the TOE may have to be restricted to meet the requirements). The evaluator shall also perform the following test: Test 1: The evaluator shall establish a SSH connection using each of the encryption algorithms specified by the requirement. It is sufficient to observe (on the wire) the successful negotiation of a protocol to satisfy the intent of the test. ASE_TSS AGD_OPE ATE_IND 26. FCS_SSH_ EXT.1.5 The assurance activity associated with FCS_SSH_EXT.1.4 verifies this requirement. N/A 27. FCS_SSH_ EXT.1.6 The evaluator shall check the TSS to ensure that it lists the supported data integrity algorithms, and that that list corresponds to the list in this component. The evaluator shall also check the operational guidance to ensure that it contains instructions to the administrator on how to ensure that only the allowed data integrity algorithms are used in SSH connections with the TOE (specifically, that the “none” MAC algorithm is not allowed). ASE_TSS Aruba Networks Security Target Page 59 of 67 # NDPP Source Requirement Assurance Family 28. FCS_SSH_ EXT.1.7 The evaluator shall ensure that operational guidance contains configuration information that will allow the security administrator to configure the TOE so that all key exchanges for SSH are performed using DH group 14. If this capability is “hard-coded” into the TOE, the evaluator shall check the TSS to ensure that this is stated in the discussion of the SSH protocol. The evaluator shall also perform the following test: Test 1: The evaluator shall attempt to perform a diffie-hellman-group1-sha1 key exchange, and observe that the attempt fails. The evaluator shall then attempt to perform a diffie-hellman-group14-sha1 key exchange, and observe that the attempt succeeds. AGD_OPE ASE_TSS ATE_IND 29. FDP_RIP.2 “Resources” in the context of this requirement are network packets being sent through (as opposed to “to”, as is the case when a security administrator connects to the TOE) the TOE. The concern is that once a network packet is sent, the buffer or memory area used by the packet still contains data from that packet, and that if that buffer is re-used, those data might remain and make their way into a new packet. The evaluator shall check to ensure that the TSS describes packet processing to the extent that they can determine that no data will be reused when processing network packets. The evaluator shall ensure that this description at a minimum describes how the previous data are zeroized/overwritten, and at what point in the buffer processing this occurs. ASE_TSS 30. FIA_PMG_ EXT.1 The evaluator shall examine the operational guidance to determine that it provides guidance to security administrators on the composition of strong passwords, and that it provides instructions on setting the minimum password length. The evaluator shall also perform the following tests. Note that one or more of these tests can be performed with a single test case. Test 1: The evaluator shall compose passwords that either meet the requirements, or fail to meet the requirements, in some way. For each password, the evaluator shall verify that the TOE supports the password. While the evaluator is not required (nor is it feasible) to test all possible compositions of passwords, the evaluator shall ensure that all characters, rule characteristics, and a minimum length listed in the requirement are supported, and justify the subset of those characters chosen for testing. AGD_OPE ATE_IND 31. FIA_UIA_E XT.1 The evaluator shall examine the TSS to determine that it describes the logon process for each logon method (local, remote (HTTPS, SSH, etc.)) supported for the product. This description shall contain information pertaining to the credentials allowed/used, any protocol transactions that take place, and what constitutes a “successful logon”. The evaluator shall examine the operational guidance to determine that any necessary preparatory steps (e.g., establishing credential material such as preshared keys, tunnels, certificates, etc.) to logging in are described. For each supported the login method, the evaluator shall ensure the operational guidance provides clear instructions for successfully logging on. If configuration is necessary to ensure the services provided before login are limited, the evaluator shall determine that the operational guidance provides sufficient instruction on limiting the allowed services. The evaluator shall perform the following tests for each method by which administrators access the TOE (local and remote), as well as for each type of credential supported by the login method: ASE_TSS ATE_IND Aruba Networks Security Target Page 60 of 67 # NDPP Source Requirement Assurance Family Test 1: The evaluator shall use the operational guidance to configure the appropriate credential supported for the login method. For that credential/login method, the evaluator shall show that providing correct I&A information results in the ability to access the system, while providing incorrect information results in denial of access. Test 2: The evaluator shall configure the services allowed (if any) according to the operational guidance, and then determine the services available to an external remote entity. The evaluator shall determine that the list of services available is limited to those specified in the requirement. Test 3: For local access, the evaluator shall determine what services are available to a local administrator prior to logging in, and make sure this list is consistent with the requirement. 32. FIA_UAU_ EXT.2 Assurance activities for this requirement are covered under those for FIA_UIA_EXT.1. If other authentication mechanisms are specified, the evaluator shall include those methods in the activities for FIA_UIA_EXT.1. ASE_TSS ATE_IND 33. FIA_UAU.7 The evaluator shall perform the following test for each method of local login allowed: Test 1: The evaluator shall locally authenticate to the TOE. While making this attempt, the evaluator shall verify that at most obscured feedback is provided while entering the authentication information. ATE_IND 34. FMT_MTD. 1 The evaluator shall review the operational guidance to determine that each of the TSF-data-manipulating functions implemented in response to the requirements of this PP is identified, and that configuration information is provided to ensure that only administrators have access to the functions. The evaluator shall examine the TSS to determine that, for each administrative function identified in the operational guidance; those that are accessible through an interface prior to administrator log-in are identified. For each of these functions, the evaluator shall also confirm that the TSS details how the ability to manipulate the TSF data through these interfaces is disallowed for non- administrative users. AGD_OPE ASE_TSS 35. FMT_SMF. 1 The security management functions for FMT_SMF.1 are distributed throughout the PP and are included as part of the requirements in FMT_MTD, FPT_TST_EXT, and any cryptographic management functions specified in the reference standards. Compliance to these requirements satisfies compliance with FMT_SMF.1. N/A 36. FMT_SMR. 2 The evaluator shall review the operational guidance to ensure that it contains instructions for administering the TOE both locally and remotely, including any configuration that needs to be performed on the client for remote administration. In the course of performing the testing activities for the evaluation, the evaluator shall use all supported interfaces, although it is not necessary to repeat each test involving an administrative action with each interface. The evaluator shall ensure, however, that each supported method of administering the TOE that conforms to the requirements of this PP be tested; for instance, if the TOE can be administered through a local hardware interface; SSH; and TLS/HTTPS; then all three methods of administration must be exercised during the evaluation AGD_OPE ATE_IND Aruba Networks Security Target Page 61 of 67 # NDPP Source Requirement Assurance Family team’s test activities. 37. FPT_SKP_ EXT.1 The evaluator shall examine the TSS to determine that it details how any pre- shared keys, symmetric keys, and private keys are stored and that they are unable to be viewed through an interface designed specifically for that purpose, as outlined in the application note. If these values are not stored in plaintext, the TSS shall describe how they are protected/obscured. ASE_TSS 38. FPT_APW _EXT.1 The evaluator shall examine the TSS to determine that it details all authentication data that are subject to this requirement, and the method used to obscure the plaintext password data when stored. The TSS shall also detail passwords are stored in such a way that they are unable to be viewed through an interface designed specifically for that purpose, as outlined in the application note. ASE_TSS 39. FPT_STM. 1 The evaluator shall examine the TSS to ensure that it lists each security function that makes use of time. The TSS provides a description of how the time is maintained and considered reliable in the context of each of the time related functions. The evaluator examines the operational guidance to ensure it instructs the administrator how to set the time. If the TOE supports the use of an NTP server, the operational guidance instructs how a communication path is established between the TOE and the NTP server, and any configuration of the NTP client on the TOE to support this communication. Test 1: The evaluator uses the operational guide to set the time. The evaluator shall then use an available interface to observe that the time was set correctly. Test2: [conditional] If the TOE supports the use of an NTP server; the evaluator shall use the operational guidance to configure the NTP client on the TOE, and set up a communication path with the NTP server. The evaluator will observe that the NTP server has set the time to what is expected. If the TOE supports multiple cryptographic protocols for establishing a connection with the NTP server, the evaluator shall perform this test using each supported protocol. ASE_TSS AGD_OPE ATE_IND 40. FPT_TUD_ EXT.1 Updates to the TOE either have a hash associated with them, or are signed by an authorized source. If digital signatures are used, the definition of an authorized source is contained in the TSS, along with a description of how the certificates used by the update verification mechanism are contained on the device. The evaluator ensures this information is contained in the TSS. The evaluator also ensures that the TSS (or the operational guidance) describes how the candidate updates are obtained; the processing associated with verifying the digital signature or calculating the hash of the updates; and the actions that take place for successful (hash or signature was verified) and unsuccessful (hash or signature could not be verified) cases. The evaluator shall perform the following tests: Test 1: The evaluator performs the version verification activity to determine the current version of the product. The evaluator obtains a legitimate update using procedures described in the operational guidance and verifies that it is successfully installed on the TOE. Then, the evaluator performs a subset of other assurance activity tests to demonstrate that the update functions as expected. After the update, the evaluator performs the version verification ASE_TSS AGD_OPE ATE_IND Aruba Networks Security Target Page 62 of 67 # NDPP Source Requirement Assurance Family activity again to verify the version correctly corresponds to that of the update. Test 2: The evaluator performs the version verification activity to determine the current version of the product. The evaluator obtains or produces an illegitimate update, and attempts to install it on the TOE. The evaluator verifies that the TOE rejects the update. 41. FPT_TST_ EXT.1 The evaluator shall examine the TSS to ensure that it details the self tests that are run by the TSF on start-up; this description should include an outline of what the tests are actually doing (e.g., rather than saying "memory is tested", a description similar to "memory is tested by writing a value to each memory location and reading it back to ensure it is identical to what was written" shall be used). The evaluator shall ensure that the TSS makes an argument that the tests are sufficient to demonstrate that the TSF is operating correctly. The evaluator shall also ensure that the operational guidance describes the possible errors that may result from such tests, and actions the administrator should take in response; these possible errors shall correspond to those described in the TSS. ASE_TSS AGD_OPE 42. FTA_SSL_ EXT.1 The evaluator shall perform the following test: Test 1: The evaluator follows the operational guidance to configure several different values for the inactivity time period referenced in the component. For each period configured, the evaluator establishes a local interactive session with the TOE. The evaluator then observes that the session is either locked or terminated after the configured time period. If locking was selected from the component, the evaluator then ensures that re-authentication is needed when trying to unlock the session. ATE_IND 43. FTA_SSL.3 The evaluator shall perform the following test: Test 1: The evaluator follows the operational guidance to configure several different values for the inactivity time period referenced in the component. For each period configured, the evaluator establishes a remote interactive session with the TOE. The evaluator then observes that the session is terminated after the configured time period. ATE_IND 44. FTA_SSL.4 The evaluator shall perform the following test: Test 1: The evaluator initiates an interactive local session with the TOE. The evaluator then follows the operational guidance to exit or log off the session and observes that the session has been terminated. Test 2: The evaluator initiates an interactive remote session with the TOE. The evaluator then follows the operational guidance to exit or log off the session and observes that the session has been terminated. ATE_IND 45. FTA_TAB. 1 The evaluator shall check the TSS to ensure that it details each method of access (local and remote) available to the administrator (e.g., serial port, SSH, HTTPS). The evaluator shall also perform the following test: Test 1: The evaluator follows the operational guidance to configure a notice and consent warning message. The evaluator shall then, for each method of access specified in the TSS, establish a session with the TOE. The evaluator shall verify that the notice and consent warning message is displayed in each ATE_TSS ATE_IND Aruba Networks Security Target Page 63 of 67 # NDPP Source Requirement Assurance Family instance. 46. FTP_ ITC.1 The evaluator shall examine the TSS to determine that, for all communications with authorized IT entities identified in the requirement, each communications mechanism is identified in terms of the allowed protocols for that IT entity. The evaluator shall also confirm that all protocols listed in the TSS are specified and included in the requirements in the ST. The evaluator shall confirm that the operational guidance contains instructions for establishing the allowed protocols with each authorized IT entity, and that it contains recovery instructions should a connection be unintentionally broken. The evaluator shall also perform the following tests: Test 1: The evaluators shall ensure that communications using each protocol with each authorized IT entity is tested during the course of the evaluation, setting up the connections as described in the operational guidance and ensuring that communication is successful. Test 2: For each protocol that the TOE can initiate as defined in the requirement, the evaluator shall follow the operational guidance to ensure that in fact the communication channel can be initiated from the TOE. Test 3: The evaluator shall ensure, for each communication channel with an authorized IT entity, the channel data is not sent in plaintext. Test 4: The evaluator shall ensure, for each communication channel with an authorized IT entity, modification of the channel data is detected by the TOE. Test 5: The evaluators shall, for each protocol associated with each authorized IT entity tested during test 1, the connection is physically interrupted. The evaluator shall ensure that when physical connectivity is restored, communications are appropriately protected. Further assurance activities are associated with the specific protocols. ASE_TSS AGD_OPE ATE_IND 47. FTP_TRP. 1 The evaluator shall examine the TSS to determine that the methods of remote TOE administration are indicated, along with how those communications are protected. The evaluator shall also confirm that all protocols listed in the TSS in support of TOE administration are consistent with those specified in the requirement, and are included in the requirements in the ST. The evaluator shall confirm that the operational guidance contains instructions for establishing the remote administrative sessions for each supported method. The evaluator shall also perform the following tests: Test 1: The evaluators shall ensure that communications using each specified (in the operational guidance) remote administration method is tested during the course of the evaluation, setting up the connections as described in the operational guidance and ensuring that communication is successful. Test 2: For each method of remote administration supported, the evaluator shall follow the operational guidance to ensure that there is no available interface that can be used by a remote user to establish a remote administrative sessions without invoking the trusted path. Test 3: The evaluator shall ensure, for each method of remote administration, the channel data is not sent in plaintext. Test 4: The evaluator shall ensure, for each method of remote administration, ASE_TSS Aruba Networks Security Target Page 64 of 67 # NDPP Source Requirement Assurance Family modification of the channel data is detected by the TOE. Further assurance activities are associated with the specific protocols. 48. FPT_ITT.1 The evaluator shall examine the TSS to determine that the methods and protocols used to protect distributed TOE components are described. The evaluator shall also confirm that all protocols listed in the TSS in support of TOE administration are consistent with those specified in the requirement, and are included in the requirements in the ST. The evaluator shall confirm that the operational guidance contains instructions for establishing the communication paths for each supported method. The evaluator shall also perform the following tests: Test 1: The evaluators shall ensure that communications using each specified (in the operational guidance) communications method is tested during the course of the evaluation, setting up the connections as described in the operational guidance and ensuring that communication is successful. Test 2: The evaluator shall ensure, for each method of communication, the channel data is not sent in plaintext. Test 3: The evaluator shall ensure, for each method of communication, modification of the channel data is detected by the TOE. Further assurance activities are associated with the specific protocols. ASE_TSS ATE_IND 49. ADV_FSP. 1 Developer Note: As indicated in the introduction to this section, the functional specification is comprised of the information contained in the AGD_OPE and AGD_PRE documentation, coupled with the information provided in the TSS of the ST. The assurance activities in the functional requirements point to evidence that should exist in the documentation and TSS section; since these are directly associated with the SFRs, the tracing in element ADV_FSP.1.2D is Implicitly already done and no additional documentation is necessary. ADV_FSP 50. ADV_FSP. 1 There are no specific assurance activities associated with these SARs. The functional specification documentation is provided to support the evaluation activities described in NDPP Section 4.2, and other activities described for AGD, ATE, and AVA SARs. The requirements on the content of the functional specification information is implicitly assessed by virtue of the other assurance activities being performed; if the evaluator is unable to perform an activity because the there is insufficient interface information, then an adequate functional specification has not been provided. ADV_FSP 51. AGD_OPE. 1 The operational guidance shall at a minimum list the processes running (or that could run) on the TOE in its evaluated configuration during its operation that are capable of processing data received on the network interfaces (there are likely more than one of these, and this is not limited to the process that "listens" on the network interface). It is acceptable to list all processes running (or that could run) on the TOE in its evaluated configuration instead of attempting to determine just those that process the network data. For each process listed, the administrative guidance will contain a short (e.g., one- or two-line) description of the process' function, and the privilege with which the service runs. "Privilege" includes the hardware privilege level (e.g., ring 0, ring 1), any software privileges specifically associated with the process, and the privileges associated with the AGD_OPE Aruba Networks Security Target Page 65 of 67 # NDPP Source Requirement Assurance Family user role the process runs as or under. 52. AGD_OPE. 1 The operational guidance shall contain instructions for configuring the cryptographic engine associated with the evaluated configuration of the TOE. It shall provide a warning to the administrator that use of other cryptographic engines was not evaluated nor tested during the CC evaluation of the TOE. AGD_OPE 53. AGD_OPE. 1 The documentation must describe the process for verifying updates to the TOE, either by checking the hash or by verifying a digital signature. The evaluator shall verify that this process includes the following steps: 1. For hashes, a description of where the hash for a given update can be obtained. For digital signatures, instructions for obtaining the certificate that will be used by the FCS_COP.1(2) mechanism to ensure that a signed update has been received from the certificate owner. This may be supplied with the product initially, or may be obtained by some other means. 2. Instructions for obtaining the update itself. This should include instructions for making the update accessible to the TOE (e.g., placement in a specific directory). 3. Instructions for initiating the update process, as well as discerning whether the process was successful or unsuccessful. This includes generation of the hash/digital signature. AGD_OPE 54. AGD_OPE. 1 The TOE will likely contain security functionality that does not fall in the scope of evaluation under the NDPP. The operational guidance shall make it clear to an administrator which security functionality is covered by the evaluation activities. AGD_OPE 55. AGD_PRE. 1 The evaluator shall check to ensure that the guidance provided for the TOE adequately addresses all platforms claimed for the TOE in the ST. AGD_PRE 56. ATE_IND.1 The evaluator shall prepare a test plan and report documenting the testing aspects of the system. The test plan covers all of the testing actions contained in the CEM and the body of the NDPP’s Assurance Activities. While it is not necessary to have one test case per test listed in an Assurance Activity, the evaluator must document in the test plan that each applicable testing requirement in the ST is covered. ATE_IND 57. ATE_IND.1 The test plan identifies the platforms to be tested, and for those platforms not included in the test plan but included in the ST, the test plan provides a justification for not testing the platforms. This justification must address the differences between the tested platforms and the untested platforms, and make an argument that the differences do not affect the testing to be performed. It is not sufficient to merely assert that the differences have no affect; rationale must be provided. If all platforms claimed in the ST are tested, then no rationale is necessary. ATE_IND 58. ATE_IND.1 The test plan describes the composition of each platform to be tested, and any setup that is necessary beyond what is contained in the AGD documentation. It should be noted that the evaluator is expected to follow the AGD documentation for installation and setup of each platform either as part of a test or as a standard pre-test condition. This may include special test drivers or tools. For each driver or tool, an argument (not just an assertion) should be provided that the driver or ATE_IND Aruba Networks Security Target Page 66 of 67 # NDPP Source Requirement Assurance Family tool will not adversely affect the performance of the functionality by the TOE and its platform. This also includes the configuration of the cryptographic engine to be used. The cryptographic algorithms implemented by this engine are those specified by this PP and used by the cryptographic protocols being evaluated (IPsec, TLS/HTTPS, SSH). 59. ATE_IND.1 The test plan identifies high-level test objectives as well as the test procedures to be followed to achieve those objectives. These procedures include expected results. The test report (which could just be an annotated version of the test plan) details the activities that took place when the test procedures were executed, and includes the actual results of the tests. This shall be a cumulative account, so if there was a test run that resulted in a failure; a fix installed; and then a successful rerun of the test, the report would show a “fail” and “pass” result (and the supporting details), and not just the “pass” result. ATE_IND 60. AVA_VAN. 1 As with ATE_IND, the evaluator shall generate a report to document their findings with respect to this requirement. This report could physically be part of the overall test report mentioned in ATE_IND, or a separate document. The evaluator performs a search of public information to determine the vulnerabilities that have been found in network infrastructure devices and the implemented communication protocols in general, as well as those that pertain to the particular TOE. The evaluator documents the sources consulted and the vulnerabilities found in the report. For each vulnerability found, the evaluator either provides a rationale with respect to its nonapplicability, or the evaluator formulates a test (using the guidelines provided in ATE_IND) to confirm the vulnerability, if suitable. Suitability is determined by assessing the attack vector needed to take advantage of the vulnerability. For example, if the vulnerability can be detected by pressing a key combination on boot-up, a test would be suitable at the assurance level of the NDPP. If exploiting the vulnerability requires expert skills and an electron microscope, for instance, then a test would not be suitable and an appropriate justification would be formulated. AVA_VAN 61. ALC_CMC. 1 The evaluator shall check the ST to ensure that it contains an identifier (such as a product name/version number) that specifically identifies the version that meets the requirements of the ST. Further, the evaluator shall check the AGD guidance and TOE samples received for testing to ensure that the version number is consistent with that in the ST. If the vendor maintains a web site advertising the TOE, the evaluator shall examine the information on the web site to ensure that the information in the ST is sufficient to distinguish the product. ALC_CMC 62. ALC_CMS. 2 The “evaluation evidence required by the SARs” in the NDPP is limited to the information in the ST coupled with the guidance provided to administrators and users under the AGD requirements. By ensuring that the TOE is specifically identified and that this identification is consistent in the ST and in the AGD guidance (as done in the assurance activity for ALC_CMC.1), the evaluator implicitly confirms the information required by this component. ALC_CMS 63. Annex C1.2 The evaluator shall check to ensure that the TSS contains a list (possibly empty except for authentication failures for user-level connections) of the protocol failures that are auditable. The evaluator shall test all identified audit events during protocol testing/audit testing. ASE_TSS ATE_IND Aruba Networks Security Target Page 67 of 67 ----- End of Document -----
