This week Insecure.org released the 2006 results of the top 100 security tools survey. The survey was performed by polling 3,243 active NMAP users (one of the most popular network security programs) on their preferred security tools. Most of the tools are free and open source and many were designed for the Unix/Linux platform.
It is a curiosity that the list of top 100 security programs could easily be called the top 100 hacking programs?both security practitioners and hackers use nearly the same toolset. For this reason it is useful to peruse this list and become familiar with the more popular tools in order to understand available capabilities for ensuring/defeating system security.
