What Is A Firewall?

A firewall is a software (or hardware) solution to enforce security policies. The software limits access to a computer over a network or from an outside source. It is used to prevent computer hackers from getting into a computer. Being online can be fraught with dangers: Spyware agents, Trojan horses, hijacker and more can cause anything from slow performance to system crash to full-blown identity theft.
