CISC-ND-001370 - The Cisco router must be configured to use an authentication server for the purpose of authenticating users prior to granting administrative access - line console
Information
Centralized management of user accounts and authentication increases the administrative access to the router. This control is 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 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
