Configure auditing of successful ownership changes

Description

Ensure that successful attempts to change an ownership of files or directories are audited. The following rules configure audit as described above:

## Successful ownership change
-a always,exit -F arch=b32 -S lchown,fchown,chown,fchownat -F success=1 -F auid>=1000 -F auid!=unset -F key=successful-owner-change
-a always,exit -F arch=b64 -S lchown,fchown,chown,fchownat -F success=1 -F auid>=1000 -F auid!=unset -F key=successful-owner-change    

Load new Audit rules into kernel by running:

augenrules --load

Note: This rule uses a special set of Audit rules to comply with OSPP 4.2.1. You may reuse this rule in different profiles. If you decide to do so, it is recommended that you inspect contents of the file closely and make sure that they are alligned with your needs.

Rationale

Auditing of successful ownership changes of files or directories helps in monitoring or investingating of activities performed on the system.
