Fix Recommendation

Configure the Ubuntu operating system to generate audit records when successful/unsuccessful attempts to use the "su" command occur.

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

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

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

# sudo augenrules --load

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

Check Contents

Verify if the Ubuntu operating system generates audit records when successful/unsuccessful attempts to use the "su" command occur.

Check the configured audit rules with the following commands:

# sudo auditctl -l | grep '/bin/su'

-a always,exit -F path=/bin/su -F perm=x -F auid>=1000 -F auid!=-1 -k privileged-priv_change

If the command does not return lines that match the example or the lines are 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.
