I see a LOT of firewall configuration files and router configuration files. It’s the bane of my auditor’s existence to read through a PIX firewall config (up to 500 pages of a text file). After the 35th page of text, you could drive a truck through that firewall while I tried to wake up.
Plus, I can’t just log on to the firewall and look at it, oh no. I’m an auditor, and we aren’t trusted with such things (probably just as well). So, when I find a tool that will look at the configuration text file, analyze it and give me a nice HTML report, I want to throw a party.
Allow me to introduce Nipper. It takes a microsecond to turn out an absolutely superb report (and found things I missed!). AND it doesn’t just do Cisco, it also handles Nortel, Sonicwall, Juniper and Nokia. I’m in love. AND I gave the guy $50.00. I hope he had a party for himself. What an awesome piece of work.
It runs in Linux or Windows, and somebody else built a GUI front end, if command line makes your eyes cross. Grab your config files and see what you might have missed.
