| 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: radius-server host 10.1.3.16 auth-port 1645 acct-port 1646 key xxxxxxxxxx … … … aaa authentication login LOGIN_AUTHENTICATION group radius local line console login authentication LOGIN_AUTHENTICATION ! line default login authentication LOGIN_AUTHENTICATION transport input ssh 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 router to use an authentication server as shown in the following example: RP/0/0/CPU0:R3(config)#radius-server host 10.1.3.16 key xxxxxxxx Step 2: Configure the authentication order to use the authentication server as primary source for authentication as shown in the following example: RP/0/0/CPU0:R3(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 as shown in the following example: RP/0/0/CPU0:R3(config)#line default RP/0/0/CPU0:R3(config-line)#login authentication LOGIN_AUTHENTICATION RP/0/0/CPU0:R3(config-line)#exit RP/0/0/CPU0:R3(config)#line console RP/0/0/CPU0:R3(config-line)#login authentication LOGIN_AUTHENTICATION |
