It's difficult but definitely not impossible to determine foul play even if there is legitimate access. And it is not necessary to "lock down" processes to the deteriment of business. This is the whole point of technology like Digital Guardian (Verdasys). Here's an example of how another federal agency more then likely would have known about NSA's insider. https://www.verdasys.com/blog/...

re: NSA Leak Ushers In New Era Of The Insider Threat
The NSA leak, and tech's response to it, pose a great conundrum. One part would be the want to lock down information even further so it can't be leaked. On another is keeping it open enough so that when something which is highly questionable (NSA spying on Americans) is able to be leaked it is able to be. The 'you have nothing to fear if you're not doing anything' meme is disturbing to see in Dark Reading, as it encourages your readers to give up their rights without any questions (be it to the government or their employers) in the name of tighter security.

The NSA is breaking the 4th amendment to the Constitution, and when someone reports it that is an insider threat? Who gave NSA the authority to break the law?

The problem is that too much access is given to someone that doesn't need it. Why does an analyst need Root access to an OS? Analyst should be required to access data through specific applications. Not directly. And an Administrator/Root/Superuser never needs to "see" data. They ara paid to manage an environment, not look at data, so systems should never decrypt for superusers. Oh did I say decrypt? What? Your data at rest isn't even encrypted? Well let's start there then! Encrypt data and surround it with strong user/role based rules that only decrypt for those that need to see or machine user IDs that actually touch data.

The problem is that there are few technologies that combine human behavioral risk analytics with traditional access and activity patterns of source systems. Finding patterns of risk apart from Peer Group activity is key, as well as visualizing anomalies with user behavior (Geolocation, login times, large file transfers/downloads, unusual data sources accessed, etc.). SIEM's or log file consolidation tools don't do this. GuruCul has created a platform (GuruCul Risk Analytics, or GRA) that creates user profile and directory meta data, and then correlates that (Hadoop) to all data sources accessed. Then they run self-learning algorithms with 232 attributes to show risky behavior. They could have seen these unusual access patterns and flagged them as anomalies to remediate. I suspect this emerging domain of "Security Intelligence" will really become a focal point going forward.
