Fix Recommendation

Configure the SUSE operating system to generate an audit record when all modifications to the "/etc/gshadow" file occur.

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

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

To reload the rules file, restart the audit daemon

> sudo systemctl restart auditd.service

or issue the following command:

> sudo augenrules --load

Check Contents

Verify the SUSE operating system generates an audit record when all modifications occur to the "/etc/gshadow" file.

Check that the file is being audited by performing the following command:

> sudo auditctl -l | grep -w '/etc/gshadow'

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

If the command does not return a line, this is a finding.

Notes:
The "-k" allows for specifying an arbitrary identifier. The string following "-k" does not need to match the example output above.
