Verify Permissions On /etc/ipsec.conf File

An XCCDF Rule

Description

To properly set the permissions of /etc/ipsec.conf, run the command:

$ sudo chmod 0644 /etc/ipsec.conf

Rationale

Setting correct permissions on the /etc/ipsec.conf file is important because this file hosts Libreswan configuration. Protection of this file is critical for system security. Restricting the permissions ensures exclusive control of the Libreswan configuration.
