These switches also support full IEEE802.3at PoE+, Cisco UPOE, modular and field-replaceable network modules, redundant fans, and power supplies. In addition, the Cisco Catalyst 9300-based models support a variety of uplink modules for both copper and fiber uplink support. These models add even more flexibility to the interface choices that you can make in a single Cisco Catalyst 9300 Series Switches or in a stack of Cisco Catalyst 9300 Series Switches. The illustration below shows a representation of Catalyst 9300 switches. All the switch models have similar appearance. The internal capabilities and port numbers distinguish the models. (a) (b) Figure 1: (a) Cisco Catalyst 9300 24 Port Series Switches and (b) Cisco Catalyst 9300 48 Port Series Switches Cisco Catalyst 9300 series has multigigabit switches with Ethernet, SFP+ and PoE+ ports and the switches also support Cisco StackWise feature. The switches include cryptographic algorithms implemented in IOS-XE firmware as well as hardware ASICs. The modules support RADsec (RADIUS over TLS), IKE/IPSec, TLS, SESA (Symmetric Early Stacking Authentication), SNMPv3, 802.11i, SSHv2, and MACsec. The cryptographic modules have two mode of operations: FIPS mode and non-FIPS mode. The non-FIPS mode is default for the switches. It is the Crypto-Officer’s responsibility to install and configure the modules in FIPS mode of operation. Detailed instructions to setup FIPS mode of operation can be found in Secure Operation section of this document. 2.1 Cryptographic Modules Interfaces and Physical Characteristics The modules are multiple-chip standalone cryptographic modules. The cryptographic boundary is defined as encompassing the “top,” “front,” “left,” “right,” and “bottom” surfaces of the chassis for the switches and the casing for the switches. Cisco Catalyst 9300 Series Switches provide support for the following features: Table 2 - Cisco Catalyst 9300 Series Switches Models and Descriptions Switch Model Description C9300-24T Stackable 24 10/100/1000 Ethernet ports; 350 WAC power supply; supports StackWise-480 and StackPower.

The logical interfaces and their mapping are described in the following tables.

Each user is authenticated upon initial access to the modules. There are two roles in the switches that may be assumed: the Crypto-Officer (CO) role and the User role. The administrator of the switches assumes the CO role in order to configure and maintain the switches using CO services, while the Users are processes that exercise security services over the network. 2.2.1 User Role The role is assumed by users obtaining secured data services. From a logical view, user activity exists in the data- plane via defined Data Input/Output Intefaces. Users are authenticated using EAP methods and 802.1X-REV, and their data is protected with 802.1AE protocols. EAP and 802.1X-REV can use password-based credentials for User role authentication – in such a case the user passwords must be at least eight (8) characters long. The password must contain at least one special character and at least one number character along with six additional characters taken from the 26-upper case, 26-lower case, 10-numbers and 32-special characters (procedurally enforced). This requirement gives (26 + 26 + 10 + 32 =) 94 options of character to choose from. Without repetition of characters, the number of probable combination is the combined probability from 6 characters (94x93x92x91x90x89) times one special character (32) times 1 number (10), which turns out to be (94x93x92x91x90x89x32x10 =) 187,595,543,116,800. Therefore, the associated probability of a successful random attempt is approximately 1 in 187,595,543,116,800, which is less than 1 in 1,000,000 required by FIPS 140-2. In order to successfully guess the sequence in one minute would require the ability to make over 3,126,592,385,280 guesses per second, which far exceeds the operational capabilities of the switches. EAP and 802.1X-REV can also authenticate the User role via certificate credentials by using 2048-bit RSA keys – in such a case the security strength is 112 bits, so the associated probability of a successful random attempt is 1 in 2112 , which is less than 1 in 1,000,000 required by FIPS 140-2. To exceed a one in 100,000 probability of a successful random key guess in one minute, an attacker would have to be capable of approximately 8.65x1031 attempts per second, which far exceeds the operational capabilities of the modules. The services available to the User role accessing the CSPs, the type of access – read (r), write (w), execute (e) and zeroized/delete (d) – and which role accesses the CSPs are listed below: Table 4 - User Services Services Description Keys and CSPs Access Secured Dataplane MACsec Network Functions: authentication, access control, confidentiality and data integrity services provided by the MACsec protocol Diffie- Hellman (DH) private key, Diffie- Hellman (DH) public key, Diffie- Hellman (DH) Shared Secret, MACsec Security Association Key (SAK), MACsec Connectivity Association Key (CAK), MACsec Key Encryption Key (KEK), MACsec Integrity Check Key (ICK), Pairwise Master Key (PMK), Protected Access Credential (PAC) Key, Pairwise Transient Key (PTK), Key Confirmation Key (KCK) (w, e, d) Bypass Services Traffic without cryptographic processing except authentication. The rule must have been previously configured by the Crypto Officer. Diffie- Hellman (DH) private key, Diffie- Hellman (DH) public key, Diffie- Hellman (DH) Shared Secret (w, e, d) 2.2.2 Crypto-Officer Role This role is assumed by an authorized CO connecting to the switches via CLI through the console port and performing management functions and modules configuration. Additionally, the stack master is considered CO for stack members. From a logical view, CO activity exists only in the control plane. IOS-XE prompts the CO for their username and password, and, if the password is validated against the CO’s password in IOS-XE memory, the CO is allowed entry to the IOS-XE executive program. A CO can assign permission to access the CO role to additional accounts, thereby creating additional COs. The cryptographic modules support RADsec for authentication of COs. CO passwords must be at a minimum eight (8) characters long. The Secure Operation sections procedurally enforces the password must contain at least one special character and at least one number character along with six additional characters taken from the 26-upper case, 26-lower case, 10-numbers and 32-special characters (procedurally enforced). This requirement gives (26 + 26 + 10 + 32 =) 94 options of character to choose from. Without repetition of characters, the number of probable combination is the combined probability from 6 characters (94x93x92x91x90x89) times one special character (32) times 1 number (10), which turns out to be (94x93x92x91x90x89x32x10 =) 187,595,543,116,800. Therefore, the associated probability of a successful random attempt is approximately 1 in 187,595,543,116,800, which is less than 1 in 1,000,000 required by FIPS 140-2. In order to successfully guess the sequence in one minute would require the ability to make over 3,126,592,385,280 guesses per second, which far exceeds the operational capabilities of the modules. Additionally, on a stack, the CO is authenticated via possession of a SESA Authorization key that is 128 bits long. So, an attacker would have a 1 in 2128 chance of a successful authentication which is much stronger than the one in a million-chance required by FIPS 140-2. To exceed a one in 100,000 probability of a successful random key guess in one minute, an attacker would have to be capable of approximately 5.67x1036 attempts per second, which is less than 1 in 100,000 and far exceeds the operational capabilities of the modules. The Crypto-Officer role is responsible for the configuration of the switches. The services available to the Crypto Officer role accessing the CSPs, the type of access – read (r), write (w), execute (e) and zeroized/delete (d) – and which role accesses the CSPs are listed below: Table 5 - Crypto-Officer Services Services Description Keys and CSPs Access Define Rules and Filters Define network interfaces and settings, create command aliases, set the protocols the switch will support, enable interfaces and network services, set system date and time, and load authentication information. Log off users, shutdown or reload the switch, manually back up switch configurations, view complete configurations, manage user rights, and restore switch configurations. Create packet Filters that are applied to User data streams on each interface. Each Filter consists of a set of Rules, which define a set of packets to permit or deny based on characteristics such as protocol ID, addresses, ports, TCP connection establishment, or packet direction.

All CSPs (d) 2.2.3 Unauthorized Role The services for someone without an authorized role are: passing traffic through the devices, view the status output from the modules’ LED pins, and cycle power. 2.2.4 Services Available in Non-FIPS Mode of Operation The cryptographic modules in addition to FIPS mode of operation can operate in a non-FIPS mode of operation. This is not a recommended operational mode but because the associated RFC’s for the following protocols allow for non-approved algorithms and non-approved key sizes a non-approved mode of operation exist. The modules are considered to be in a non-FIPS mode of operation when it is not configured per section 3 (Secure Operation of the Switches). The FIPS approved services listed in table 5 become non-approved services when using any non-approved algorithms or non-approved key or curve sizes. Table 6 - Non-approved algorithms in the Non-FIPS mode services Services 1 Non-Approved Algorithms IPsec Hashing: MD5 MACing: HMAC MD5 1 These approved services become non-approved when using any of non-approved algorithms or non-approved key or curve sizes. When using approved algorithms and key sizes these services are approved.

Approved Cryptographic Algorithms The switches support the following FIPS-2 approved algorithm implementations: Table 7 – CAVP Algorithm Certificates Algorithms CAVP #A1462: IOS Common Cryptographic Module (IC2M) Rel5a2 CAVP #C431: CiscoSSL FIPS Object Module 6.23 CAVP #4769: UADP MSC 1.0 CAVP #C220: Firmware Image Signing AES CBC (128, 192, 256), CFB128 (128, 192, 256), CMAC (128, 256), CTR (128, 192, 256), ECB (128, 192, 256), GCM (128, 192, 256) CBC(128, 192, 256), CCM(128, 192, 256), CFB1/8/128(128, 192, 256), CMAC(128, 192, 256), CTR(128, 192, 256), ECB(128, 192, 256), GCM(128, 192, 256), KW(128, 192, 256), OFB (128, 192, 256) XTS(128, 256) ECB (128, 256) GCM (128, 256) N/A KAS-ECC-SSC (NIST SP 800-56Arev3) KAS-ECC-SSC: Curves: P-256 P-384 N/A N/A N/A KAS-FFC-SSC (SP 800-56Arev3) KAS-FFC-SSC: modp-2048 modp-3072 modp-4096 N/A N/A N/A DRBG CTR-AES (256) CTR-AES (128, 192, 256), SHA-1, SHA2-224, SHA2- 384, SHA2-512 HMAC (SHA-1, SHA2-224, SHA2-384, SHA2-512) N/A N/A HMAC HMAC SHA-1, HMAC SHA2-256, HMAC SHA2- 384, HMAC SHA2-512 HMAC SHA-1, HMAC SHA2- 224, HMAC SHA2-384, HMAC SHA2-512 N/A N/A 2 AES-GCM was tested as part of CAVP algorithm testing (A1462), but it is not utilized by the modules. 3 AES-XTS was tested as part of CAVP algorithm testing (C:431), but it is not utilized by the modules.

Only the algorithms, modes, and key sizes that are implemented by the modules are shown in this table. The modules’ AES-GCM implementation conforms to IG A.5 scenario #1 following RFC 5288 for TLS and RFC 7296 for IPSec/IKEv2. The modules are compatible with TLSv1.2 and provides support for the acceptable GCM cipher suites from SP 800-52 Rev1, Section 3.3.1. The 64-bit counter portion of the 96-bit IV is set by the modules within its cryptographic boundary. When the IV exhausts the maximum number of possible values (0 to 264 - 1) for a given session key, the first party, client or server, to encounter this condition will trigger a handshake to establish a new encryption key. In case the modules’ power is lost and then restored, a new key for use with the AES GCM encryption/decryption shall be established. The modules use RFC 7296 compliant IKEv2 to establish the shared secret SKEYSEED from which the AES GCM encryption keys are derived. When the IV exhausts the maximum number of possible values for a given session key, the first party, client or server, to encounter this condition will trigger a handshake to establish a new encryption key. In case the modules’ power is lost and then restored, a new key for use with the AES GCM encryption/decryption shall be established. No parts of the SSH, TLS and IPSec protocols, other than the KDFs, have been tested by the CAVP and CMVP. In accordance with FIPS 140-2 IG D.12, the cryptographic modules perform Cryptographic Key Generation as per scenario 1 of section 5 in SP800-133. The resulting generated symmetric key and the seed used in the asymmetric key generation are the unmodified output from SP800-90A DRBG. The module utilizes AES Key wrap (AES Certs. #C431) in accordance with SP800-38F. Non-FIPS Approved Algorithms Allowed in FIPS Mode RSA (key wrapping; key establishment methodology provides between 112 and 128 bits of encryption strength; non-compliant less than 112 bits of encryption strength) when used with modulus size of 2048 bits or greater NDRNG to seed FIPS approved DRBG (256 bits) Non-FIPS Approved Algorithms The cryptographic modules implement the following non-Approved algorithms that are not used in FIPS mode of operation: MD5 HMAC-MD5 RC4 Triple-DES DES HMAC-SHA1 with key size less than 112-bits 2.4 Cryptographic Key/CSP Management The modules securely administer both cryptographic keys and other critical security parameters such as passwords. All keys are also protected by the password-protection on the CO role login, and can be zeroized by the CO. Keys are exchanged and entered electronically. Persistent keys are entered by the CO via the console port CLI, transient keys are generated or established and stored in DRAM. Note that the command ‘fips zeroize’ will zeroize a large majority of the listed CSPs. This command essentially results in a device reboot and therefore forces a power cycle, zeroizing all the keys listed below with “Power cycle” in the Zeroization Method column. Table 8 lists the secret and private cryptographic keys and CSPs used by the modules.

All power-on self-tests must be passed before each role starts to perform services. The power-on self-tests are performed after the cryptographic systems are initialized but prior to the initialization of the LAN’s interfaces; this prevents the AP’s from passing any data during a power-on self-test failure. 2.6 Physical Security The cryptographic modules entirely contained within production-grade enclosure. The chassis of the modules have removable covers. 3 Secure Operation The switches meet all the overall Level 1 requirements for FIPS 140-2. Follow the setup instructions provided below to place the modules in FIPS-approved mode. Operating this Switches without maintaining the following settings will remove the modules from the FIPS approved mode of operation. 3.1 System Initialization and Configuration 1. Login through the management port with the default username is “cisco”; the default password is the serial number of the switch chassis. The CO must change the password for consecutive login. 2. The CO must create the “enable” password for the CO role. Procedurally, the password must be at least 8 characters, including at least one letter and at least one number, and is entered when the CO first engages the “enable” command. The CO enters the following syntax at the “#” prompt: Switch(config)# enable secret [PASSWORD] 3. The CO must always assign passwords (of at least 8 characters, including at least one letter and at least one number) to users. Identification and authentication on the console/auxiliary port is required for Users. From the “configure terminal” command line, the CO enters the following syntax: Switch(config)# line con 0 Switch(config)# password [PASSWORD] Switch(config)# login local 4. The value of the boot field must be 0x0102. This setting disables break from the console to the ROM monitor and automatically boots. From the “configure terminal” command line, the CO enters the following syntax: config-register 0x0F 5. Disable Telnet and configuring Secure Shell for remote command line: Switch(config)# line vty line_number [ending_line_number] or Switch(config)# transport input ssh 6. Disable the following interfaces by configuration: a. USB 3.0 Switch(config)# hw-module switch 1 usbflash1 security enable password [password] b. Wireless Console Access with Bluetooth Switch(config)# hw-module beacon rp active off 7. To ensure all FIPS 140-2 logging is received, set the log level: Switch(config)# logging console error 8. The CO enables secure stacking (SESA) but configuring the Authorization key: Switch(config)# fips authorization-key <128 bit, i.e, 16 hex byte key> 9. The CO may configure the modules to use RADsec for authentication. If the modules are configured to use RADsec, the Crypto Officer must define RADIUS or shared secret keys that are at least 8 characters long, including at least one letter and at least one number. 10. The CO shall only assign users to a privilege level 1 (the default). 11. The CO shall not assign a command to any privilege level other than its default.
