Fix Recommendation

Step 1: Configure the Cisco router to use at least two authentication servers as shown in the following example:

R4(config)#radius host 10.1.48.2 key xxxxxx
R4(config)#radius host 10.1.48.3 key xxxxxx

Step 2: Configure the authentication order to use the authentication servers as the primary source for authentication as shown in the following example:

R4(config)#aaa authentication login CONSOLE group radius local

R4(config)#aaa authentication login LOGIN_AUTHENTICATION group radius local

Step 3: Configure all network connections associated with device management to use the authentication servers for the purpose of login authentication.

R4(config)#line vty 0 1
R4(config-line)#login authentication LOGIN_AUTHENTICATION
R4(config-line)#exit
R4(config)#line con 0
R4(config-line)#login authentication CONSOLE
R4(config-line)#exit
R4(config)#ip http authentication aaa login-authentication LOGIN_AUTHENTICATION

Check Contents

Review the Cisco router configuration to verify the device is configured to use at least two authentication servers as the primary source for authentication as shown in the following example:

aaa new-model
!
aaa authentication login CONSOLE group radius local
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 1812 acct-port 1813 key xxxxxxx
radius-server host x.x.x.x auth-port 1812 acct-port 1813 key xxxxxxx
…
…
…
line con 0
exec-timeout 5 0
login authentication CONSOLE
line vty 0 1
exec-timeout 5 0
login authentication LOGIN_AUTHENTICATION

If the Cisco router is not configured to use at least two authentication servers for the purpose of authenticating users prior to granting administrative access, this is a finding.
