Multi-Agent Systems (MAS) have been widely used in many areas like modeling and simulation of complex phenomena, and distributed problem solving. Likewise, MAS have been used in cyber-security, to build more efficient Intrusion Detection Systems (IDS), namely Collaborative Intrusion Detection Systems (CIDS). This work presents a taxonomy for classifying the methods used to design intrusion detection systems, and how such methods were used alongside with MAS in order to build IDS that are deployed in distributed environments, resulting in the emergence of CIDS. The proposed taxonomy, consists of three parts: 1) general architecture of CIDS, 2) the used agent technology, and 3) decision techniques, in which used technologies are presented. The proposed taxonomy reviews and classifies the most relevant works in this topic and highlights open research issues in view of recent and emerging threats. Thus, this work provides a good insight regarding past, current, and future solutions for CIDS, and helps both researchers and professionals design more effective solutions.

this article deals with the implementation of an industrial process simulator (steam generator with feed water station), our system was carried out using the multi-agent approach Because of the importance of this functional approach compared to the objectoriented approach, currently used and becoming more and more important in the field of modeling and computer simulation.Thus, the purpose of our system is to realize a virtual copy of the industrial installation of this process; this copy is intended to enable the practical training of future operators to control industrial installation. It offers an opportunity to recreate real situations, analyze control loops performances and discover the constitutions and equipment installation.
