Unless you have the smallest of small Windows networks, odds are you don't know everything about every system that...
may need to be tested for security flaws. I'm talking about systems like Exchange, IIS, SharePoint, SQL Server and so on. What do other people affected by your security testing (both the process and the outcomes) know about the systems they manage daily that can make your assessments easier? They may be able to help you narrow or broaden your scope and determine exactly what needs to be tested and when. Ask your DBAs, developers and desktop support people what they think are critical areas to test. Dare I say, talk to your marketing and business development folks and see what questions (and demands) they are hearing from clients and business partners. This input can point you down the right path.
Also, what technical information do you need from these people to help you with your testing? Information like IP addresses, specific production servers, Windows user accounts and passwords, and locations are necessary items to have. They may also be able to tell you which systems are critical for production and may be sensitive to the wear and tear of security testing. Bonus: When you get others involved in this capacity, they're more likely to help you when trouble arises.
