Abstract

Insider threats are one of the serious hard problems of organizational security because it is often unclear whether or not an actor is an insider, or what we actually mean by “insider”. In addition, it is frequently almost impossible to verify if an authorized insider action (authorized at the level of an operational policy) would constitute an insider attack contravening the organizational security policy of an enterprise. Hence, research on how to fight against insider attacks is one of the recent major topics in information security. This special issue aims at showcasing the most recent challenges and advanced technologies for managing insider security threats. It collects a series of papers selected for presentation at the fourth International Workshop on Managing Insider Security Threat1 (MIST’12), Nishijin Plaza, Kyushu University, Fukuoka, Japan, November 8-9, 2012.
