Check: CISC-ND-001370
Cisco IOS XE Switch NDM STIG:
CISC-ND-001370
(in versions v2 r2 through v1 r0.1)
Title
The Cisco switch must be configured to use an authentication server for the purpose of authenticating users prior to granting administrative access. (Cat I impact)
Discussion
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.
Check Content
Review the Cisco switch 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 Cisco switch is not configured to use an authentication server for the purpose of authenticating users prior to granting administrative access, this is a finding.
Fix Text
Step 1: Configure the Cisco switch to use an authentication server as shown in the following example: SW4(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: SW4(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. SW4(config)#line vty 0 4 SW4(config-line)#login authentication LOGIN_AUTHENTICATION SW4(config-line)#exit SW4(config)#line con 0 SW4(config-line)#login authentication LOGIN_AUTHENTICATION SW4(config-line)#exit SW4(config)#ip http authentication aaa login-authentication LOGIN_AUTHENTICATION
