This survey paper categorises, compares, and summarises details from published technical and review articles in intrusion and fraud detection. It defines the professional fraudster, formalises the main types and subtypes of known fraud. The goal of this paper is to provide a comprehensive survey of different techniques to detect intrusion and frauds.
