| Firewall System
Firewall is a protective boundary
and line of defense for a computer network. A network
without a proper firewall system can be attacked by
the hackers and unauthorized users and once they enter
in the computer network they can perform any unwanted
actions like stealing the confidential data, attacking
the network with viruses and spyware etc. Every computer
in a network especially the gateway computer should
have proper firewall software installed and configured.
By default, Windows XP Professional provides the built-in
firewall features. Network administrator can configure
the firewall at any desired level, according to the
security requirements of the network. You can block
and allow any IP request with the firewall system.
The other third party firewall software includes Zonealrm,
Personal Firewall, Prisma Firewall, Comodo Firewall
Pro 3, Secure Point Personal firewall and VPN client.
