Firewall

-
We can easily said that firewall is a program which is prevents unauthorized access to or from a private network. Firewalls are tools that can be used to enhance the security of computers connected to a network, such as LAN or the Internet. They are an integral part of a comprehensive security framework for your network.

What firewall do?
  • Defend resources
  • Validate access
  • Manage and control network traffic
  • Record and report on events
  • Act as an intermediary
A Personal firewall is important when
  • You surf the Internet at home using an 'always on' broadband connection
  • You connect to the Internet via a public WiFi network in a park, cafe or airport
  • You run a home network which needs to be kept isolated from the Internet
  • You wish to be kept informed when any program on your computer attempts to connect to the Internet
  • Most Personal Firewalls are highly configurable so you can easily create security policies to suit your individual needs.
