Nmap Security Tool Survey

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."

    remember that these tools aren't going to be the "end all/be all" of network security.

    You also have to have a good preventive security plan, which these tools will help out in. However, there should also be a plan of action should these security measures get bypassed (i.e. an insider job, program exploits, trojans, etc...)

    But that's just my contention...

      In Bastille Linux's defense, we try very hard to educate the sysadmin/user so they'll make better decisions. Bastille tries to educate the user, to help her build a good hardening policy for her hosts and hopefully her site.


      And that education is one of the few things that will actually keep your sysadmins or users from blowing the entire site's security away with a bad decision... Who cares if you're proactively scanning for open ports when you don't know why some of those open ports are worse than others? Your admin has to know that allowing Samba/CIFS/Windows filesharing through the perimeter firewall is asking to be hurt badly. Your admin has to know that setting every Unix box to give root via rsh from a particular (spoofable) IP addess is asking for a domino effect.
