Suppose a user walks into the office with a laptop which has been compromised, plugs it into the network, it punches a hole out through the firewall to nasty hacker, effectively giving the nasty hacker access to your internal network. Is the firewall still going to protect your possibly vulnerable webapps then?

What about the user that plugs a modem into their pc for whatever reason, and a random wardialer stumbles across it?

Or the "I think i know what I'm doing" user who plugs in a wireless AP?

Food for thought ;)

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
