The Cisco router must accept Personal Identity Verification (PIV) credentials.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-96459	CISC-ND-001110	SV-105597r1_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.

Check Text ( C-95295r1_chk )
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: radius-server host 10.1.3.16 auth-port 1645 acct-port 1646 key xxxxxxxxxx … … … aaa authentication login LOGIN_AUTHENTICATION group radius local line console login authentication LOGIN_AUTHENTICATION ! line default login authentication LOGIN_AUTHENTICATION transport input ssh If the router is not configured to use an authentication server to authenticate and authorize users for administrative access, this is a finding.

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

Fix Text (F-102135r2_fix)

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
