The present invention relates to a dynamic safety method and system based on multi-fusion linked responses. The method comprises: an on-site control apparatus providing, by means of identity authentication and key management, an active response or passive response to provide an alarm for an abnormal behavior. The system comprises an access authentication-related active response module, an access control-related active response module, an access control-related passive response module, an abnormal identity theft-related passive response module, a key weakness-related passive response module, and an abnormal condition-related passive response mechanism module. The present invention enables establishment of a secure and reliable operation environment for an industrial control system while ensuring correctness and feasibility of security protection of a terminal apparatus.
