Title
The operating system must automatically audit account disabling actions. (Cat II impact)
Discussion
When operating system accounts are disabled, user accessibility is affected. The system must audit account disablement actions so that administrator users can detect and respond to such events. Such a capability greatly reduces the risk that operating system accessibility will be negatively affected for extended periods of time and provides logging that can be used for forensic purposes. To address access requirements, many operating systems can be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.
Check Content
In order to view the currently configured flags for the audit daemon, run the following command: sudo grep ^flags /etc/security/audit_control The account modification events are logged by way of the 'ad' flag. If 'ad' is not listed in the result of the check, this is a finding.
Fix Text
To make sure the appropriate flags are enabled for auditing, run the following command: sudo sed -i.bak '/^flags/ s/$/,ad/' /etc/security/audit_control; sudo audit -s A text editor may also be used to implement the required updates to the /etc/security/audit_control file.
