SLEM-05-654065 - SLEM 5 must generate audit records for all uses of the "newgrp" command.

Information

Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information.

At a minimum, the organization must audit the full-text recording of privileged commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise.

Solution

Configure SLEM 5 to generate an audit record for all uses of the "newgrp" command.

Add or modify the following line 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!=unset -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
