Consequently, Intrusion Detection Systems (IDS) are quickly becoming a popular requirement in building a network security infrastructure. Most existing IDS are generally centralized and suffer from a number of drawbacks, e.g., high rates of false positives, low efficiency, etc, especially when they face distributed attacks. This paper introduces a novel hybrid multi-agents IDS based on the intelligent combination of a clustering technique and an ontology model, called OCMAS-IDS. The latter integrates the desirable features provided by the multi-agents methodology with the benefits of semantic relations as well as the high accuracy of the data mining technique. Carried out experiments showed the efficiency of our distributed IDS, that sharply outperforms other systems over real traffic and a set of simulated attacks. %G English %Z TC 5 %2 https://inria.hal.science/hal-01789978/document %2 https://inria.hal.science/hal-01789978/file/339159_1_En_31_Chapter.pdf %L hal-01789978 %U https://inria.hal.science/hal-01789978 %~ INSTITUT-TELECOM %~ CNRS %~ TELECOM-SUDPARIS %~ IFIP-LNCS %~ IFIP %~ IFIP-AICT %~ IFIP-TC %~ IFIP-TC5 %~ IFIP-AICT-456 %~ IFIP-CIIA %~ INSTITUTS-TELECOM
