Fix Recommendation

Configure the audit system to generate an audit event for any successful/unsuccessful use of the "chsh" command.

Add or modify the following line in the "/etc/audit/rules.d/stig.rules" file:

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

To reload the rules file, issue the following command:

$ sudo augenrules --load

Note: The "-k <keyname>" at the end of the line gives the rule a unique meaning to help during an audit investigation. The <keyname> does not need to match the example above.

Check Contents

Verify Ubuntu 22.04 LTS generates an audit record upon successful/unsuccessful attempts to use the "chsh" command by using the following command:

$ sudo auditctl -l | grep chsh
-a always,exit -S all -F path=/usr/bin/chsh -F perm=x -F auid>=1000 -F auid!=-1 -F key=priv_cmd

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

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