Fix Recommendation

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

R4(config)#radius server RADIUS1
R4(config-radius-server)#address ipv4 x.x.x.x auth-port 1812 acct-port 1813
R4(config-radius-server)#key xxxxxxx
R4(config-radius-server)#radius server RADIUS2
R4(config-radius-server)#address ipv4 x.x.x.x auth-port 1812 acct-port 1813
R4(config-radius-server)#key xxxxxxx

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 group server radius RADIUS_GROUP
R4(config)#server name RADIUS1
R4(config)#server name RADIUS2

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

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

Step 3: Configure all network connections associated with a 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

Review the Cisco switch 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 group server radius RADIUS_GROUP
server name RADIUS1
server name RADIUS2
!
aaa authentication login CONSOLE group RADIUS_GROUP local
aaa authentication login LOGIN_AUTHENTICATION group RADIUS_GROUP local
…

radius server RADIUS1
address ipv4 x.x.x.x auth-port 1812 acct-port 1813
key xxxxxxx

radius server RADIUS2
address ipv4 x.x.x.x auth-port 1812 acct-port 1813
key xxxxxxx
…

line con 0

login authentication CONSOLE
line vty 0 1

login authentication LOGIN_AUTHENTICATION

If the Cisco switch 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.
