Here is a good overview of the problem and possible solutions for Insider Threats in the Cyber world. Unfortunately the e-book is put out by Kaspersky Lab's who just got caught with leaked internal memos to the Russian Government that they had trap doors in their security system to let the Russians in. But the document here seems solid and I do think the over view of the insider threat is valid. I learned from it, and I study the problem all the time. So well worth the read.
