Information

The Cisco switch must be configured to use at least two authentication servers for the purpose of authenticating users prior to granting administrative access.

GROUP ID: V-220565
RULE ID: SV-220565r961863

Centralized management of user accounts and authentication increases the administrative access to the switch. This control is a particularly important protection against the insider threat. With robust centralized management, audit records for administrator account access to the organization's network devices can be more readily analyzed for trends and anomalies. The alternative method of defining administrator accounts on each device exposes the device configuration to remote access authentication attacks and system administrators with multiple authenticators for each network device.

Solution

Step 1: Configure the Cisco switch 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 primary source for authentication as shown in the following example:

R4(config)#aaa authentication CONSOLE local

R4(config)#aaa authentication login
LOGIN_AUTHENTICATION group radius 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
