1.1 Firewall and Router standards

Firewalls and routers are considered key components of the IT architecture. They both control network streams, and are entry and exit points. Proper configuration standards help with defining a good policy on what is allowed, or what kind of traffic should be blocked. Linux systems that act as a router, have the option IP forwarding enabled. Firewall which pass on traffic to different network segments will have this as well. Ensure that there are proper standards in place to determine when IP forwarding should be enabled and how such systems should be properly configured.
