Verify Group Who Owns /etc/chrony.keys File

An XCCDF Rule

Description

To properly set the group owner of /etc/chrony.keys, run the command: 
$ sudo chgrp chrony /etc/chrony.keys

Rationale

The ownership of the /etc/chrony.keys file by the chrony group is important because this file hosts chrony cryptographic keys. Protection of this file is critical for system security. Assigning the ownership to chrony ensures exclusive control of the chrony cryptography keys.
