Fix Recommendation

Configure the audit system to generate audit events showing start and stop times for user access via the "/var/log/btmp file".

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

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

To reload the rules file, issue the following command:

$ sudo augenrules --load

Check Contents

Verify Ubuntu 24.04 LTS generates audit records showing start and stop times for user access to the system via the "/var/log/btmp" file with the following command:

$ sudo auditctl -l | grep '/var/log/btmp'
-w /var/log/btmp -p wa -k logins

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

Note: The "-k" allows for specifying an arbitrary identifier, and the string after it does not need to match the example output above.
