Abstract: Industrial control system (ICS) is the core of the infrastructure. With the development of computer internet and the integration of information and industrialization. industrial control system is gradually merging with internet, breaking the original hermetic. ICS suffers the threaten from virus, Trojans and others. For the above reasons, ICS is facing increasingly serious information security issues now. This paper introduces the progress of industrial control safety research at home and abroad from the aspects of structure. We explain structure, vulnerability, existing threat and anomaly detection of industrial control system. And focus on the analysis of anomaly detection methods. Finally, we combined with the domestic industrial safety, make recommendations on industrial safety, and prospects for development prospects.

Key words: industrial control system (ICS), supervisory control and data acquisition (SCADA), cyber-physical system (CPS), cyber security, intrusion detection
