Firewall
A firewall is a device that controls access to your internal network.
Firewalls are installed at any points in your network where you need to control access; for example, between your internal information network and the external world. They act as gatekeepers, enforcing access rules and permissions. In this way, they protect your network resources from other networks and intruders.
Traditionally firewalls are devices that only enforce access policies. However, as they evolve, many now include advanced application awareness and security capabilities such as intrusion prevention, anti-virus protection, and content filtering.
