assist the end user of this product and any security certification Agent for that end user in determining the suitability of this Information Technology (IT) product for their environment. End users should review the Security Target (ST), which is where specific security claims are made, in conjunction with this VR, which describes how those security claims were tested and evaluated and any restrictions on the evaluated configuration. Prospective users should carefully read the Assumptions and Clarification of Scope in Section 5 and the Validator Comments in Section 10, where any restrictions on the evaluated configuration are highlighted. This report documents the National Information Assurance Partnership (NIAP) assessment of the evaluation of the Pulse Policy Secure v9.1 Target of Evaluation (TOE). It presents the evaluation results, their justifications, and the conformance results. This VR is not an endorsement of the TOE by any agency of the U.S. Government and no warranty of the TOE is either expressed or implied. This VR applies only to the specific version and configuration of the product as evaluated and documented in the ST. The evaluation was completed by Acumen Security in March 2020. The information in this report is largely derived from the Evaluation Technical Report (ETR) and associated test report, all written by Acumen Security. The evaluation determined that the product is both Common Criteria Part 2 Extended and Part 3 Conformant and meets the assurance requirements defined in the collaborative Protection Profile for Network Devices, Version 2.1. The Target of Evaluation (TOE) identified in this Validation Report has been evaluated at a NIAP approved Common Criteria Testing Laboratory using the Common Methodology for IT Security Evaluation (Version 3.1, Rev. 5) for conformance to the Common Criteria for IT Security Evaluation (Version 3.1, Rev. 5), as interpreted by the Assurance Activities contained in the collaborative Protection Profile for Network Devices, Version 2.1. This Validation Report applies only to the specific version of the TOE as evaluated. The evaluation has been conducted in accordance with the provisions of the NIAP Common Criteria Evaluation and Validation Scheme and the conclusions of the testing laboratory in the evaluation technical report are consistent with the evidence provided. 5 2 Identification The CCEVS is a joint National Security Agency (NSA) and National Institute of Standards effort to establish commercial facilities to perform trusted product evaluations. Under this program, security evaluations are conducted by commercial testing laboratories called Common Criteria Testing Laboratories (CCTLs). CCTLs evaluate products against Protection Profile containing Assurance Activities, which are interpretation of CEM work units specific to the technology described by the PP. The NIAP Validation Body assigns Validators to monitor the CCTLs to ensure quality and consistency across evaluations. Developers of information technology products desiring a security evaluation contract with a CCTL and pay a fee for their product's evaluation. Upon successful completion of the evaluation, the product is added to NIAP's Product Compliance List. Table 1 provides information needed to completely identify the product, including:  The Target of Evaluation (TOE): the fully qualified identifier of the product as evaluated.  The Security Target (ST), describing the security features, claims, and assurances of the product.  The conformance result of the evaluation.  The Protection Profile(s) to which the product is conformant.  The organizations and individuals participating in the evaluation.

PPS allows administrators to define, implement, and enforce policy by enabling endpoint discovery, monitoring, and alerting. The TOE is classified as a network device (a generic infrastructure device that can be connected to a network) or a virtual network device (a Virtual Appliance that can be connected to a network) depending on the underlying platform. The TOE software consists of Pulse Policy Secure (PPS) 9.1. The appliance’s software is built on IVE OS 2.0. The TOE consists of the PPS application, IVE OS, and either the TOE hardware or the VM hypervisor, all of which are delivered with the TOE. The TOE hardware consists of either the PSA Models 300, 3000, 5000, 7000C, or 7000F. 7 4 Security Policy The TOE provides the security functionality required by NDcPP v2.1, September 24, 2018. 4.1 Security Audit The TOE generates audit records for security relevant events. The TOE maintains a local audit log as well as sending the audit records to a remote Syslog server. Audit records sent to the remote server are protected by a TLS connection. Each audit record includes identity (username, IP address, or process), date and time of the event, type of event, and the outcome of the event. The TOE prevents modification to the local audit log. 4.2 Cryptographic Support The TOE includes the Pulse Secure Cryptographic Module that implements CAVP validated cryptographic algorithms for random bit generation, encryption/decryption, authentication, and integrity protection/verification. These algorithms are used to provide security for the TLS and HTTPs connections for secure management and secure connections to a syslog server. TLS and HTTPs are also used to verify firmware updates. 4.3 Identification and Authentication The TOE authenticates administrative users using a username/password or username/X.509 certificate combination. The TOE does not allow access to any administrative functions prior to successful authentication. The TOE validates and authenticates X.509 certificates for all certificate uses. The TOE supports passwords consisting of alphanumeric and special characters and enforces minimum password lengths. The TSF supports certificates using RSA or ECDSA signature algorithms. The TOE only allows users to view the login warning banner and send/receive ICMP packets prior to authentication. Remote administrators are locked out after a configurable number of unsuccessful authentication attempts. 4.4 Security Management The TOE allows users with the Security Administrator role to administer the TOE over a remote web UI or a local CLI. These interfaces do not allow the Security Administrator to execute arbitrary commands or executables on the TOE. Security Administrators can manage connections to an external Syslog server, as well as determine the size of local audit storage. 4.5 Protection of the TSF The TOE implements several self-protection mechanisms. It does not provide an interface for the reading of secret or private keys. The TOE ensures timestamps, timeouts, and certificate checks are accurate by maintaining a real-time clock. Upon startup, the TOE runs a suite of self-tests to verify that it is operating correctly. The TOE also verifies the integrity and authenticity of firmware updates by verifying a digital signature of the update prior to installing it. 8 4.6 TOE Access The TOE can be configured to display a warning and consent banner when an administrator attempts to establish an interactive session over the local CLI or remote web UI. The TOE also enforces a configurable inactivity timeout for remote and local administrative sessions. 4.7 Trusted Path/Channels The TOE uses TLS to provide a trusted communication channel between itself and remote Syslog servers. The trusted channels utilize X.509 certificates to perform mutual authentication. The TOE initiates the TLS trusted channel with the remote server. The TOE uses HTTPS/TLS to provide a trusted path between itself and remote administrative users. The TOE does not implement any additional methods of remote administration. The remote administrative users are responsible for initiating the trusted path when they wish to communicate with the TOE. 9 5 Assumptions, Threats & Clarification of Scope 5.1 Assumptions The specific conditions listed in the following subsections are assumed to exist in the TOE’s environment. These assumptions include both practical realities in the development of the TOE security requirements and the essential environmental conditions on the use of the TOE. ID Assumption A.PHYSICAL_PROTECTION The network device is assumed to be physically protected in its operational environment and not subject to physical attacks that compromise the security and/or interfere with the device’s physical interconnections and correct operation. This protection is assumed to be sufficient to protect the device and the data it contains. As a result, the cPP will not include any requirements on physical tamper protection or other physical attack mitigations. The cPP will not expect the product to defend against physical access to the device that allows unauthorized entities to extract data, bypass other controls, or otherwise manipulate the device. A.LIMITED_FUNCTIONALITY The device is assumed to provide networking functionality as its core function and not provide functionality/services that could be deemed as general purpose computing. For example, the device should not provide computing platform for general purpose applications (unrelated to networking functionality). A.NO_THRU_TRAFFIC_PROTECTION A standard/generic network device does not provide any assurance regarding the protection of traffic that traverses it. The intent is for the network device to protect data that originates on or is destined to the device itself, to include administrative data and audit data. Traffic that is traversing the network device, destined for another network entity, is not covered by the ND cPP. It is assumed that this protection will be covered by cPPs and PP-Modules for particular types of network devices (e.g, firewall). A.TRUSTED_ADMINISTRATOR The Security Administrator(s) for the network device are assumed to be trusted and to act in the best interest of security for the organization. This includes being appropriately trained, following policy, and adhering to guidance documentation. Administrators are trusted to ensure passwords/credentials have sufficient strength and entropy and to lack malicious intent when administering the device. The network device is not expected to be capable of defending against a malicious administrator that actively works to bypass or compromise the security of the device. For TOEs supporting X.509v3 certificate-based authentication, the Security Administrator(s) are expected to fully validate (e.g. offline verification) any CA certificate (root CA certificate or intermediate CA certificate) loaded into the TOE’s trusted source (aka ‘root store’, ‘trusted CA Key Store’, or similar) as a trust anchor prior to use (e.g. offline verification). A.REGULAR_UPDATES The network device firmware and software is assumed to be updated by an administrator on a regular basis in response to the release of product updates due to known vulnerabilities. A.ADMIN_CREDENTIALS_SECURE The administrator’s credentials (private key) used to access the network device are protected by the platform on which they reside. 10 A.COMPONENTS_RUNNING (applies to distributed TOEs only) For distributed TOEs it is assumed that the availability of all TOE components is checked as appropriate to reduce the risk of an undetected attack on (or failure of) one or more TOE components. It is also assumed that in addition to the availability of all components it is also checked as appropriate that the audit functionality is running properly on all TOE components. A.RESIDUAL_INFORMATION The Administrator must ensure that there is no unauthorized access possible for sensitive residual information (e.g. cryptographic keys, keying material, PINs, passwords etc.) on networking equipment when the equipment is discarded or removed from its operational environment. 5.2 Threats The following table lists the threats addressed by the TOE and the IT Environment. The assumed level of expertise of the attacker for all the threats identified below is Enhanced-Basic. ID Threat T.UNAUTHORIZED_ADMINISTRATOR_ACCESS Threat agents may attempt to gain administrator access to the network device by nefarious means such as masquerading as an administrator to the device, masquerading as the device to an administrator, replaying an administrative session (in its entirety, or selected portions), or performing man-in-the-middle attacks, which would provide access to the administrative session, or sessions between network devices. Successfully gaining administrator access allows malicious actions that compromise the security functionality of the device and the network on which it resides. T.WEAK_CRYPTOGRAPHY Threat agents may exploit weak cryptographic algorithms or perform a cryptographic exhaust against the key space. Poorly chosen encryption algorithms, modes, and key sizes will allow attackers to compromise the algorithms, or brute force exhaust the key space and give them unauthorized access allowing them to read, manipulate and/or control the traffic with minimal effort. T.UNTRUSTED_COMMUNICATION_CHANNELS Threat agents may attempt to target network devices that do not use standardized secure tunneling protocols to protect the critical network traffic. Attackers may take advantage of poorly designed protocols or poor key management to successfully perform man-in-the-middle attacks, replay attacks, etc. Successful attacks will result in loss of confidentiality and integrity of the critical network traffic, and potentially could lead to a compromise of the network device itself. T.WEAK_AUTHENTICATION_ENDPOINTS Threat agents may take advantage of secure protocols that use weak methods to authenticate the endpoints – e.g. a shared password that is guessable or transported as plaintext. The consequences are the same as a poorly designed protocol, the attacker could masquerade as the Administrator or another device, and the attacker could insert themselves into the network stream and perform a man-in-the-middle attack. The result is the critical 11 network traffic is exposed and there could be a loss of confidentiality and integrity, and potentially the network device itself could be compromised. T.UPDATE_COMPROMISE Threat agents may attempt to provide a compromised update of the software or firmware which undermines the security functionality of the device. Non-validated updates or updates validated using non-secure or weak cryptography leave the update firmware vulnerable to surreptitious alteration. T.UNDETECTED_ACTIVITY Threat agents may attempt to access, change, and/or modify the security functionality of the network device without administrator awareness. This could result in the attacker finding an avenue (e.g., misconfiguration, flaw in the product) to compromise the device and the administrator would have no knowledge that the device has been compromised. T.SECURITY_FUNCTIONALITY_COMPROMISE Threat agents may compromise credentials and device data enabling continued access to the network device and its critical data. The compromise of credentials includes replacing existing credentials with an attacker’s credentials, modifying existing credentials, or obtaining the administrator or device credentials for use by the attacker. T.PASSWORD_CRACKING Threat agents may be able to take advantage of weak administrative passwords to gain privileged access to the device. Having privileged access to the device provides the attacker unfettered access to the network traffic, and may allow them to take advantage of any trust relationships with other network devices. T.SECURITY_FUNCTIONALITY_FAILURE An external, unauthorized entity could make use of failed or compromised security functionality and might therefore subsequently use or abuse security functions without prior authentication to access, change or modify device data, critical network traffic or security functionality of the device. 5.3 Clarification of Scope All evaluations (and all products) have limitations, as well as potential misconceptions that need clarifying. This text covers some of the more important limitations and clarifications of this evaluation. Note that:  As with any evaluation, this evaluation only shows that the evaluated configuration meets the security claims made, with a certain level of assurance. The level of assurance for this evaluation is defined within the collaborative Protection Profile for Network Devices, Version 2.1.  Consistent with the expectations of the Protection Profile, this evaluation did not specifically search for, nor seriously attempt to counter, vulnerabilities that were not “obvious” or vulnerabilities to objectives not claimed in the ST. The CEM defines an “obvious” vulnerability as one that is easily exploited with a minimum of understanding of the TOE, technical sophistication and resources. 12  The evaluation of security functionality of the product was limited to the functionality specified in the claimed PPs. Any additional security related functional capabilities included in the product were not covered by this evaluation. 13 6 Documentation The following documents were provided by the vendor with the TOE for evaluation:  Pulse Policy Secure v9.1 Security Target, V1.1, March 16, 2020  Pulse Secure Operational User Guidance and Preparative Procedures, V1.2, March 2020 14 7 TOE Evaluated Configuration 7.1 Evaluated Configuration The TOE consists of the following hardware:  PSA 300  PSA 3000  PSA 5000  PSA 7000C  PSA 7000F Running:  Pulse Policy Secure (PPS) v9.1 The PPS software runs on any of the TOE hardware appliance platforms or on a virtual appliance. The TOE is delivered with the PCS v9.1 software installed on one of the PSA appliances. The TOE can also be a virtual appliance on VMware ESXi 6.0, with a Dell PowerEdge R430R530 as the hardware platform. ESXi is a bare-metal hypervisor so there is no underlying operation system. In the evaluated configuration, there are no guest VMs on the physical platform providing non-network device functionality. 7.2 Excluded Functionality The TOE includes the following functionality that is not covered in this Security Target and may not be enabled or used in in the CC evaluated configuration:  DMI Agent  SNMP Traps  External Authentication Servers for administrator authentication 15 8 IT Product Testing This section describes the testing efforts of the developer and the evaluation team.
