Fix Recommendation

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

Add or update the following rule to "/etc/audit/rules.d/stig.rules":

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

Note:
The "root" account must be used to view/edit any files in the /etc/audit/rules.d/ directory.

In order 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/gshadow.

Check the currently configured audit rules with the following command:

# sudo auditctl -l | grep gshadow

-w /etc/gshadow -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.
