Verify Permissions On /etc/iptables Directory

An XCCDF Rule

Description

To properly set the permissions of /etc/iptables, run the command: 
$ sudo chmod 0700 /etc/iptables

Rationale

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