It is important to understand the different types of insiders and the need for insider threat mitigation. Protecting against insider threats is an inherently difficult challenge because of the insider’s access to, authority over, and knowledge of the facility. Several strategies and best practices for insider threat mitigation implemented at different facilities of national importance are elaborated in this chapter. These insider threat mitigation strategies are being practiced in some countries very rigorously through regulations and enforcement. The available data presented on such instances of implementation shows the need for a rigorous implementation of fitness-for-duty, fatigue assessment, and behavioral observation programs. In some countries, some of these strategies of insider threat mitigation are implemented as a best practice but not institutionalized through regulations and enforcement for various reasons, some of which are cultural or societal. Hence, there is a need to keep trying, assessing, testing, and exchanging ideas among countries around the world. There is no room for complacency, which is always the enemy of effective security.
