Fix Recommendation

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.

R4(config)#line vty 0 4
R4(config-line)#login authentication LOGIN_AUTHENTICATION
R4(config-line)#exit
R4(config)#line con 0
R4(config-line)#login authentication LOGIN_AUTHENTICATION
R4(config-line)#exit
R4(config)#ip http authentication aaa login-authentication LOGIN_AUTHENTICATION

Check Contents

Review the Cisco 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 Cisco router is not configured to use an authentication server for the purpose of authenticating users prior to granting administrative access, this is a finding.
