Firewall Implementation and Maintenance Print E-mail

An Internet firewall is the most fundamental part of your network’s external security. With the level of threat and worm activity on the Internet, no system should ever be directly connected to the Net without at least a basic NAT device such as a Linksys router. More sophisticated networks need a higher level of protection. A Sonicwall firewall, for example, includes advanced features such as protection against ‘denial of service’ attacks.

And don’t forget home systems. A home system without a firewall device that accesses network resources should be considered as much of a security threat as an unguarded PC on your network, especially if it accesses resources through VPN or other connectivity.
