RE: Exploit through firewall question

Another scenario is if you're doing VA or pentesting to support of something
like the Security Testing and Evaluation (ST&E) part of a Certification and
Accreditation (C&A) process.  You'll want to enumerate as many of the raw
vulnerabilities on your systems so the TRA can have real vulnerabilities to
work with.  It's one thing to enumerate vulnerabilities and another to
determine exposure and the appropriate effectiveness of safeguards based on
threat agents and threat scenarios and their likelihood of exploiting the
residual risk.

What would be the reason to test behind the firewall?
Insider threats?
What if another box was compromised right next to this one?
That box could be used as a springboard for other attacks. These new
attacks would originate from behind the firewall.

Thanks for the responses. You've confirmed what I had passed to mgmt. But
I still have a problem (with mgmt) understanding why?...


I perform vulnerability analysis on our outside (public) web presense,
usually during development and then after it's been deployed. I basically
use the same tools for each.


Mgmt wants me to only test through the firewall as if I'm coming in like
the public. The rational is that the fw will prevent any attacks though
ports other than 80 and 443. Therefore, there is no reason to change this
configuration.


What would be the reason to test behind the firewall?


Any suggestions?


Thanks
