Firefighters have the potential to enhance security by allowing firewall management of large machines on a variety of systems and systems to provide access to telecommunications equipment. These firewalls can use different types of signatures and access points to allow or impede traffic. Although it may seem complicated, it is simple to install, configure and implement managed firewalls.

Most people think of a port as a device on the network and control how it works through the system.
