Fix Recommendation

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

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

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

Note:
The "root" account must be used to view/edit any files in the /etc/audit/rules.d/ directory.

In order to reload the rules file, issue the following command:

# sudo augenrules --load

Check Contents

Verify the Ubuntu operating system generates an audit record when successful/unsuccessful attempts to use the "sudoedit" command occur.

Check the configured audit rules with the following commands:

# sudo auditctl -l | grep /usr/bin/sudoedit

-a always,exit -F path=/usr/bin/sudoedit -F perm=x -F auid>=1000 -F auid!=-1 -k priv_cmd

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

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