Verify Group Who Owns /etc/crypttab File
An XCCDF Rule
Description
To properly set the group owner of /etc/crypttab, run the command:
$ sudo chgrp root /etc/crypttab
Rationale
The ownership of the /etc/crypttab file by the root group is important because this file hosts encrypted block devices configuration. Protection of this file is critical for system security. Assigning the ownership to root ensures exclusive control of the encrypted block devices configuration.
