Penetration Test Assistance

[Timothy.Green at ManTech.com (Green, Timothy)]

Howdy all,

I'm a Security Manager of a large network, we are conducting a Pentest next month and the testers are demanding a complete network diagram of the entire network.  We don't have a "complete" network diagram that shows everything and everywhere we are.  At most we have a bunch of network diagrams that show what we have in various areas throughout the country. I've been asking the network engineers for over a month and they seem to be too lazy to put it together or they have no idea where everything is.

I've never been in this situation before.  Should I be honest to the testers and tell them here is what we have, we aren't sure if it's accurate;  find everything else?  How would they access those areas that we haven't identified?   How can I give them access to stuff that I didn't know existed?

What do you all do with your large networks?  One huge network diagram, a bunch of network diagrams separated by region, or both?  Any pentest horror stories?

Thanks,

Tim
