The first thing you need: Permission. You may have gone already too far
by scanning the system with nmap. Get permission from as far high up as
possible. Permission from the "systems guy" is probably not sufficient.
I can't find it right now, but I think there is a permission slip sample
somewhere at sans.org/rr
Next, think about what you try to accomplish. If its the first time for
you, try to do a test run on a junker at home.
If your goal is to get a cute 'hacker demo' running for the
administrators, keep it brief and obvious.
- tcpdump to just sniff traffic
- nmap for a quick portscan
- nessus for a more comprehensive automated vulnerability scan.
Also a quick google search for various software packages they use may
