After the tremendously successful 2000 and 2003 top security tools surveys, we are pleased to release our 2006 results at a brand new site: SecTools.Org. A record 3,243 Nmap users responded this year. Notable trends since 2003 include the rise in exploitation frameworks such as Metasploit, Impact, and Canvas; the increased popularity of wireless tools such as Kismet and Aircrack. 44 tools are new to the list. Security practitioners are encouraged to read the list and investigate tools they aren't familiar with. You may find the little gem that you never knew you needed.
