The Cisco router must be configured to automatically audit account enabling actions.

Description
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply enable a new or disabled account. Notification of account enabling is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the creation of application user accounts and notifies administrators and Information System Security Officers (ISSO). Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes.

Check Text ( C-95119r1_chk )
Review the router configuration to determine if it automatically audits account enabling. The configuration should look similar to the example below: archive log config logging enable Note: Configuration changes can be viewed using the show archive log config all command. If account enabling is not automatically audited, this is a finding.

Fix Text (F-101961r1_fix)
Configure the router to log account enabling using the following commands: R4(config)#archive R4(config-archive)#log config R4(config-archive-log-cfg)#logging enable R4(config-archive-log-cfg)#end
