Abstract

A method of computer security for a host computer system in communication with remote computer systems, including generating an attack map as a directed graph data structure modelling individual events leading to an exploitation of the host computer system and collecting a log of each of a plurality of attack events occurring at the host including network packets involved in each attack event, the attack map being generated in a training phase of the host computer system in which the host is subjected to attacks by one or more attacking remote computer systems, using stacked autoencoders to extract features from the log event in each attack; generating a directed graph representation based on each of the extracted features, using the attack map to identify a sequence of events indicative of an attack, and responsive to the identification, deploying one or more security facilities to mitigate the attack.
