Open Source For Perimeter Security

ITObserver has an article describing the use of various open sourc projects to build a security architecture: Open Source For Perimeter Security.

There is a widespread and wholly inaccurate impression that open source development is somehow haphazard and undisciplined, a free-for-all among brilliant but uncoordinated individuals. In fact, most major open source projects are very tightly managed highly disciplined teams. This article gives examples of very successful Open Source security projects "netfilter and Snort" and also describes some weaknesses that need to be addressed by IT organizations or vendors.
