Fix Recommendation

Configure OL 9 to generate audit records upon successful/unsuccessful attempts to use the chsh command by adding or updating the following rule in "/etc/audit/rules.d/audit.rules":

-a always,exit -F path=/usr/bin/chsh -F perm=x -F auid>=1000 -F auid!=unset -k priv_cmd

The audit daemon must be restarted for the changes to take effect.

Restart auditd:
$ sudo service auditd restart

Check Contents

Verify that OL 9 is configured to audit the execution of the chsh command with the following command:

$ sudo auditctl -l | grep chsh
-a always,exit -F path=/usr/bin/chsh -F perm=x -F auid>=1000 -F auid!=unset -k priv_cmd

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