Formal Mitigation Strategies for the Insider Threat

<p>The advancement of technology and reliance on information systems have fostered an environment of sharing and trust. The rapid growth and dependence on these systems however creates an increased risk associated with the insider threat. The insider threat is one of the most challenging problems facing the security of information systems because the insider already has capabilities within the system. Despite research efforts to prevent and detect insiders organizations remain susceptible to this threat because of inadequate security policies and a willingness of some individuals to betray their organization. To investigate these issues a formal security model and risk analysis framework are used to systematically analyze this threat and develop effective mitigation strategies. This research extends the Schematic Protection Model to produce the first comprehensive security model capable of analyzing the safety of a system against the insider threat. The model is used to determine vulnerabilities in security policies and system implementation. Through analysis mitigation strategies that effectively reduce the threat are identified. Furthermore an action-based taxonomy that expresses the insider threat through measurable and definable actions is presented.</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
