An adversary who attacks an organization from within can prove fatal to the organization and is generally impervious to conventional defenses. Drawn from the findings of an award-winning thesis, Managing the Insider Threat: No Dark Corners is the first comprehensive resource to use social science research to explain why traditional methods fail against these trust betrayers. In this groundbreaking book, author Nick Catrantzos identifies new management, security, and workplace strategies for categorizing and defeating insider threats. The book begins with problem definition and research findings that lead to the “No Dark Corners” strategy for addressing insider threats. With these foundational underpinnings, the book then examines agents of change within the workplace?namely, key players in positions to effectively support or undermine the No Dark Corners strategy, including corporate sentinels and leaders affecting application of this approach. From there, the author goes on to examine key areas where No Dark Corners-style engagement can make a difference in the way an institution counters insider threats?through rethinking background investigations, recognizing deception, and using lawful disruption. Moving progressively from the theoretical to the practical in applying the strategy within an organizational framework, the book looks at implementation challenges and offers a framework for introducing new insider defense insights into an organization. Each chapter offers questions to stimulate discussion and exercises or problems suitable for team projects. This practical resource enables those charged with protecting an organization from internal threats to circumvent these predators before they jeopardize the workplace and sabotage business operations.
