Description
To assure accountability and prevent unauthenticated access, organizational administrators must be uniquely identified and authenticated for all network management accesses to prevent potential misuse and compromise of the system. This control does not apply to the root account (when applicable) or the account of last resort which are considered to be authorized shared accounts.

The Cisco router is not compliant with this requirement. However, the risk associated with this requirement can be fully mitigated if the router is configured to utilize an authentication server to authenticate and authorize users for administrative access. Review the router configuration to verify that the device is configured to use an authentication server as primary source for authentication as shown in the following example: aaa new-model ! aaa authentication login LOGIN_AUTHENTICATION group radius local … … … ip http authentication aaa login-authentication LOGIN_AUTHENTICATION ip http secure-server … … … radius-server host x.x.x.x auth-port 1645 acct-port 1646 key xxxxxxx … … … line con 0 exec-timeout 10 0 login authentication LOGIN_AUTHENTICATION line vty 0 4 exec-timeout 10 0 login authentication LOGIN_AUTHENTICATION If the router is not configured to use an authentication server to authenticate and authorize users for administrative access, this is a finding.

Step 1: Configure the Cisco router to use an authentication server as shown in the following example: R4(config)#radius host 10.1.48.2 key xxxxxx Step 2: Configure the authentication order to use the authentication server as primary source for authentication as shown in the following example: R4(config)#aaa authentication login LOGIN_AUTHENTICATION group radius local Step 3: Configure all network connections associated with a device management to use an authentication server for the purpose of login authentication.
