Access control, identity management and the insider threat
The detection of insider threats before catastrophic events occur continues to plague many industries, and the aviation industry is under particular pressure to detect possible infiltration by terrorists and their sympathisers posing as credible workers. This paper outlines a method to incorporate system dynamics into identity and access management systems designs to detect the possibility of an insider threat. The research results show that when specific policy-based rules were applied to the access control system and forensics were applied to the resulting data, it was possible to detect unusual behaviours that would have otherwise gone undetected. The practical implication of this research can lead to the development of an operational framework whereby access control data could be analysed in real time to detect and suggest insider threat signatures.
