Fix Recommendation

Configure the SUSE operating system to generate an audit record for all uses of the "newgrp" command.

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

-a always,exit -F path=/usr/bin/newgrp -F perm=x -F auid>=1000 -F auid!=4294967295 -k privileged-newgrp

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 for all uses of the "newgrp" command.

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

> sudo auditctl -l | grep -w '/usr/bin/newgrp'

-a always,exit -S all -F path=/usr/bin/newgrp -F perm=x -F auid>=1000 -F auid!=-1 -k privileged-newgrp

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

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