Fix Recommendation

Configure the Ubuntu operating system to generate audit records for all account creations, modifications, disabling, and termination events that affect "/etc/shadow".

-w /etc/shadow -p wa -k usergroup_modification

To reload the rules file, issue the following command:

$ sudo augenrules --load

Check Contents

Verify the Ubuntu operating system generates audit records for all account creations, modifications, disabling, and termination events that affect "/etc/shadow".

Check the currently configured audit rules with the following command:

$ sudo auditctl -l | grep shadow

-w /etc/shadow -p wa -k usergroup_modification

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