Firewall Support

Firewall is a security utility which investigates the incoming and the outgoing traffics on the basis of certain set of rules and other criteria. Firewalls can be deployed either with hardware or software, or a combination of both. All data entering or leaving the intranet passes through the firewall, which inspects each message and blocks those that do not meet the specified security parameters. Some of the routers are also coming with built-in firewall to take care of your computer network.

There are several types of firewall techniques deployed to check malicious content. A few includes, packet filtering, application gateway, circuit-level gateway, proxy server and more. The proxy server efficiently hides the true network addresses for security reason. A fully featured firewall protects your computer against viruses, spyware, phishing and other attacks. However, third-party software brands such as ZoneAlarm, AVG and more are available too in the industry, which have developed software with built-in firewall.
