A firewall is a set of related programs that protects the resources of a network. Firewalls are a must for every network administrator. NO network admin can dream of running a network without a firewall.

A firewall acts a barrier and keeps destructive forces away from the network. For network security and for the computers connected to that network firewall is a must. A firewall working with a router examines each packet and decides whether it can be forwarded to its destination. A firewall also works along with a proxy server that makes network request. It is made sure that no incoming requests can pass to the network going through the firewall.

Firewalls usually carry out 3 different methods. These are Packet Filtering, Proxy Services and Stateful Inspection. For mobile users, firewalls allow remote access for which the users are able to connect to the domain. To protect your important and sensitive information Firewall Configuration is very important.
