Modeling and Analysis of Insider Threat Vulnerabilities

More than 40% of computer and organizational security professionals believe that their greatest security threat is insider threat vulnerabilities where employees jeopardized security through data leaks or similar errors. Insider threat vulnerabilities are of growing interest and importance in system security but are not well understood. This talk discusses the role of social interactions in an organization and the insider threats it presents on system vulnerabilities.

In this keynote, we review various types of social engineering attacks and discuss a three-step approach to model and investigate the effects of social interactions and the risks it present. Firstly, we show how user’s roles, security policies and their interactions are modeled as facts and interaction rules. Secondly, a reasoning engine combines these facts, interaction rules and the system hardware/software configurations to produce an attack graph. The attack graph represents the cumulative effect of attack steps an intruder can take to gain system privileges through series of individual steps or network paths. Lastly, we show how an attack graph is analyzed to obtain an objective measure of cybersecurity risks and to prioritize security hardening measures among others. For examples “how likely is it that an intruder could gain privilege X?”, “which user group and system component are most vulnerable?” Some results on the impact of security leakage due to user interactions on system vulnerabilities are discussed.
