Firewalls :::: What They Are And Why You MUST Have One!Written by Titus Hoskins
A firewall is a system or gateway that prevents unauthorized access to your computer or private network. It is usually first line of defense in protecting your private information or data. A good firewall will help protect you from malicious attacks of spyware, adware, malware, worms, trojans, and hackers.
Firewalls are security mechanisms that control who can access and send data thru your network or computer. They can be applied to both hardware and software on your computer; many systems use a combination of each for greater protection. All data or messages entering or leaving your computer has to pass thru firewall, which checks all messages and blocks those that don't meet your specified security criteria or rules.
To put it in simple terms: think of a firewall as a security guard or a security scanner for your computer or network. Anything going in or out must be checked thru this system and must obey your rules!
Of course, this is just a simple explanation, firewalls can be very complex; consisting of a whole combination of techniques that can be used in concert depending on level of security you wish to achieve.
These firewall techniques may include:
Application gateway -- places security mechanisms on specific applications (FTP, Telnet, etc.)
Packet filters -- examines each packet using your computer and accepts or rejects according to your rules
Circuit-level gateway -- security measures for such connections as TCP (Transmission Control Protocol) or UDP (User Datagram Protocol)
