摘要: We present a novel Intrusion Detection System able to detect complex attacks SCADA systems. By attack, we mean set of commands (carried in Modbus packets) that, while licit when considered isolation on single-packet basis, interfere with the correct behavior system. The proposed IDS detects such thanks an internal representation controlled system and corresponding rule language, powerful enough express system's critical states. Furthermore, detail implementation provide experimental comparative results.
