VLAD the Scanner - A freeware, open-source scanner that checks for common security problems. VLAD checks for the items referenced in the SANS Top Ten list of common security problems, found at http://www.sans.org/topten.htm. While freeware scanners are not neccessarily unique, VLAD is rather unique because of the amount of vulnerable CGI programs it checks for, and its comprehensive account/password checks (seven different protocols).
