 And just because you can't get in (in the time alloted) doesn't mean 
THEY can't get in.

OTOH, it helps to get "hands on" and take a look at things from an 
outsider's perspective. Not penetration testing, just looking at what's 
really there, not what a site has documented as being there.

For example - I just took a look at a client network that ran a vertical 
database app that was supposedly secure. There were a number of "joe" 
accounts on the system, the database consisted of a series of flat files 
with the data  avail. in plain ol' ASCII, and permissions were 777 
throughout the app's directory structure. It does help to look around a 
bit, and fix what you find. Just don't fall into the trap of thinking 
that since nothing was found, everything is secure.
