Firewalls

A firewall is an information technology (IT) security device which is configured to permit, deny or proxy data connections set and configured by the organization's security policy. For anyone using a router, usually with a built in firewall, you are advised to log into the router and get familiar with all of the options it makes available. A firewall is a set of related programs, located at a network gateway server, that protects the resources of a private network from users from other networks. Improve your Internet security by using secure email, firewall router and personal firewall, anti-virus, anti-trojan, or anti-spyware software.
