spring writes "Every so often, the author of everyone's favorite network reconnaissance tool, nmap, runs a survey to determine which security-oriented software products are most popular. This year's tool survey was just released, and it contains some interesting results. Old favorites like Nessus, Snort, Netcat, and Ethereal made the list, of course. SAINT and SARA are still around. But a number of new tools appeared this year, like Windows-only GFI LANguard, SuperScan, and Cain & Abel. Nikto and Kismet demonstrate the growing importance of wireless networks. The survey contains many good tools. Certainly worth a read."
