Re: Why Penetration Test?

[intel96 <intel96 () bellsouth net>]

One question I have not seen yet concerning is why PenTest is:  To 
justify your job and a budget.  On one project a customer had a harden 
Internet router, a Cisco PIX firewall, and IDS from ISS and an IPS from 
TippingPoint.  All scanning (NMAP, Nessus, etc.) was pointless, 
everything was bocked except port 80 and 443. Most web logins required 
SecurID tokens (brute forcing these right..!!)  I was able to used SQL 
injections to create local accounts, upload files, but not download, 
because all outbound requested went through a proxy.  The customer even 
reconfigured the network each day to see if they could catch.

Now the biggest questions that I get from the customer is how did you 
bypass by filters (IDS, IPS) and I need you to rewrite the final  report 
so I can obtain more funding.........to buy more security and hire more 
people.....the biggest hole that I found was the lack of security 
internal process.  These things require leadership to fix not more 
funding!!!!!!!!! How do you state that in a report?

So IMHO every project is different based on the customer's needs (more 
funding and more head count).  The other issue is how to set the clowns 
apart from the professionals, which is becoming harder to do because 
there are more clowns and not enough professional and the clowns are 
hurting the rest of us....
