Fix Recommendation

Configure the audit system to generate an audit event for any successful/unsuccessful modifications to the "lastlog" file.

Add or modify the following line in the "/etc/audit/rules.d/stig.rules" file:

-w /var/log/lastlog -p wa -k logins

To reload the rules file, issue the following command:

$ sudo augenrules --load

Note: The "-k <keyname>" at the end of the line gives the rule a unique meaning to help during an audit investigation. The <keyname> does not need to match the example above.

Check Contents

Verify Ubuntu 22.04 LTS generates an audit record when successful/unsuccessful modifications to the "lastlog" file occur by using the following command:

$ sudo auditctl -l | grep 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 "-k" value is arbitrary and can be different from the example output above.
