This paper presents a novel layered cyber-attack detection approach utilising: 1) semantic relationships between attacks to infer possible related suspicious network activities from connections between hosts; 2) contextual information expressed as attack context profiles on top of semantic relationships. The combined use of context and semantics in intrusion detection results in predicting attacks with higher accuracy while decreasing the number of false positives at the same time. A prototype system has been implemented and experiments have been conducted on it. The results exhibit higher or competitive detection rates compared with other existing approaches.
