Insider threats pose significant challenges to any organization. Many solutions have been proposed in the past to detect insider threats. Unfortunately, given the complexity of the problem and the human factors involved, many solutions which have been proposed face strict constraints and limitations when it comes to the working environment. As a result, many past insider threat solutions have in practice failed in their implementations. In this work, we review some of the recent insider threat detection solutions and explore their benefits and limitations. We also discuss insider threat issues for emerging areas such as cloud computing, virtualization, and social networking.
