The Cisco switch must be configured to implement replay-resistant authentication mechanisms for network access to privileged accounts.

Description
A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be vulnerable to a replay attack. An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message.

Check Text (C-220488r1026069_chk)

Review the Cisco router configuration to verify it is compliant with this requirement as shown in the example below. SSH Example ssh macs hmac-sha2-256 hmac-sha2-512 NOTE: Using "fips mode enable" to enable all FIPS protocols disables TACACS+ and RADIUS, which is required for authentication server requirements. It is recommended to enable FIPS-validated protocols manually and keep FIPS mode disabled. If the Cisco router is not configured to use FIPS-validated HMAC to protect the integrity of remote maintenance sessions, this is a finding.

Fix Text (F-22192r1015484_fix)

Configure SSH to use FIPS-validated HMAC for remote maintenance sessions as shown in the following example: SSH Example R1(config)#ssh macs hmac-sha2-256 hmac-sha2-512
