The Cisco device must be configured to audit all administrator activity.

This requirement supports nonrepudiation of actions taken by an administrator and is required to maintain the integrity of the configuration management process. All configuration changes to the network device are logged, and administrators authenticate with two-factor authentication before gaining administrative access. Together, these processes will ensure the administrators can be held accountable for the configuration changes they implement. To meet this requirement, the network device must log administrator access and activity.

Review the Cisco router configuration to verify that it is compliant with this requirement as shown in the example below. hostname R1 ! logging userinfo ! … … … archive log config logging enable logging size 1000 notify syslog contenttype plaintext hidekeys ! Note: The logging userinfo global configuration command will generate a log when a user increases their privilege level. If logging of administrator activity is not configured, this is a finding.

Configure the router to log administrator activity as shown in the example below. R1(config)#logging userinfo R1(config)#archive R1(config-archive)#log config R1(config-archive-log-cfg)#logging enable R1(config-archive-log-cfg)#logging size 1000 R1(config-archive-log-cfg)#notify syslog contenttype plaintext R1(config-archive-log-cfg)#hidekeys R1(config-archive-log-cfg)#end
