This past week I received two days of Peach Fuzz training by the author Michael Eddington. This is a great fuzzing tool that is extremely powerful, yet extremely extensible and flexible. Michael did a great job in teaching the class; it probably helps that he's the author of the program. For those of you doing pen testing or research into application bugs, this program is for you. We used it in class to find (known) bugs in a few applications. But the possibilities are endless.
However, as an DoD auditor, I just don't see the use. I won't have time while on a client site to get this up and running as there is so much more for me to do on site. We are usually cramped for time with many different technologies and platforms to test. And really, contractually, I don't believe we are authorized to pen-test. We run web application scanners, but we can not exploit the vulnerabilities we find.
Awesome tool, though. And I'm glad I was given the opportunity to attend the class.
