Overview

Finding ID Version Rule ID IA Controls Severity
V-96313 CISC-ND-001110 SV-105451r1_rule Medium
Description
The use of PIV credentials facilitates standardization and reduces the risk of unauthorized access. DoD has mandated the use of the CAC to support identity management and personal authentication for systems covered under HSPD 12, as well as a primary component of layered protection for national security systems.

The Cisco router is not compliant with this requirement. However, the risk associated with this requirement can be fully mitigated if the router is configured to utilize an authentication server to authenticate and authorize users for administrative access.

Review the 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 router is not configured to use an authentication server to authenticate and authorize users for administrative access, this is a finding.
Fix Text (F-101989r1_fix)
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
