Easy APF Firewall Setup

by damonp on August 29, 2005

in SysAdmin

Running a server with no firewall exposes every network port on the box to potential misuse. Without a firewall, an administrator must know what ports are enabled and what is running on each of them to be sure the server is locked down. A firewall provides the added layer of protection of being able to close all ports from one configuration file. Server security works best with a multi-layered approach instead of relying on a single point of failure. Many firewall applications also have the ability to limit access from certain locations in case of an undue amount of traffic coming from a single IP address

A good, simple firewall that works on most servers is Advanced Policy Firewall (APF) from rfxNetworks.
