Abstract
Various embodiments include an industrial control system security analysis method. The method may include: collecting a communication data packet of interactive data transmitted between control devices in a first industrial control system; extracting network identifiable information; and determining whether it matches a pre-created event database. If the information matches: determining that the communication data packet is a malicious data packet; acquiring security policies of the first industrial control system and a second industrial control system; and determining a threat coefficient of the communication data packet for the second industrial control system based on the network identifiable information and each of the security policies, wherein the threat coefficient represents a degree of threat of the communication data packet to the second industrial control system.
