Discussion

Without generating audit records specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).

Verify SLEM 5 generates an audit record when all modifications to the "lastlog" file occur with the following command:

     > sudo auditctl -l | grep -w '/var/log/lastlog'
     -w /var/log/lastlog -p wa -k logins

If the command does not return a line that matches the example or the line is commented out, this is a finding.

Note: The "key=" value is arbitrary and can be different from the example output above.
