Summary

Network security has never been as important on the Macintosh as it is with Mac OS X. The new Mac operating system, based on a BSD core, provides a wider variety of network services than any previous release. Luckily, Mac OS X includes a variety of tools that can fend off attacks before they occur—without the need for additional software.

Many users will find that their needs are met by simply applying TCP wrappers to their critical services, and shutting down those protocols that aren't being used. Advanced users can employ ipfw or BrickHouse to provide low-level control over the flow of network traffic to and from the Mac OS X computer. In addition, administrators might want to take proactive measures by employing an intrusion detection tool such as Tripwire or PortSentry. These applications can detect an attack and react to it—potentially saving your system, data, and peace of mind.
