Detecting and Countering Insider Threats: Can Policy-Based Access Control Help?

J. Crampton, Michael Huth

Research output: Chapter in Book/Report/Conference proceedingConference contribution


As insider threats pose very significant security risks to IT systems, we ask what policy-based approaches to access control can do for the detection, mitigation or countering of insider threats and insider attacks. Answering this question is difficult since little public data about insider-threat cases is available, since there is not much consensus about what the insider problem actually is, and since research in access control has by-and-large not dealt with this issue in the past. We explore existing notions of insiderness in order to identify the relevant research issues. We then formulate a set of requirements for next-generation access-control systems whose realization might form part of an overall strategy at addressing the insider problem.
