Verify Group Who Owns /etc/iptables Directory

Description

To properly set the group owner of /etc/iptables, run the command:

$ sudo chgrp root /etc/iptables

Rationale

The ownership of the /etc/iptables directory by the root group is important because this directory hosts iptables configuration. Protection of this file is critical for system security. Assigning the ownership to root ensures exclusive control of the iptables configuration.
