StateMiner: an efficient similarity-based approach for optimal mining of role hierarchy
TLDR
This paper formally defines the problem of mining role hierarchy with minimal perturbation and presents StateMiner, a heuristic solution to find an RBAC state as similar as possible to both the existing state and the optimal state.

Inside the Mind of the Insider: Towards Insider Threat Detection Using Psychophysiological Signals
TLDR
The use of human bio-signals to detect the malicious activities and its applicability for insider threats detection are examined to show that human brain and heart signals can reveal valuable knowledge about the malicious behaviors and could be an effective solution for detecting insider threats.

Brain Computer Interface (BCI) Applications: Privacy Threats and Countermeasures
TLDR
First comprehensive analysis of BCI App stores including software development kits (SDKs), application programming interfaces (APIs), and BCI applications w.r.t privacy issues shows that most applications have unrestricted access to users' brainwave signals and can easily extract private information about their users without them even noticing.
