Analysis of Research on Specific Insider Information Security Threats

The survey of related works on insider information security (IS) threats is presented. Special attention is paid to works that consider the insiders’ behavioral models as it is very up-to-date for behavioral intrusion detection. Three key research directions are defined: (1) the problem analysis in general, including the development of taxonomy for insiders, attacks and countermeasures; (2) study of a specific IS threat with forecasting model development; (3) early detection of a potential insider. Among the second group the works on two IS threats are examined, namely intellectual property’s theft and insider cyber fraud. A few directions of future research are defined in conclusion.
