The invention discloses an attack detection and identification system based on zero dynamic industrial control, which includes an industrial control modeling module, an attack detection module and an attack identification module: the industrial control modeling module is used to construct a structural model framework of an industrial control system for petrochemical and electric power industries; the attack detection The module is used to extract the corresponding attack status observations and features, including building a centralized attack detection filter model and a distributed attack detection filter model; the attack recognition module is used to build a centralized attack recognition filter to identify the corresponding attack set. The present invention also relates to a zero-dynamic industrial control attack detection and recognition method, and proposes a security model and an attack detection and recognition filter for industrial control systems to detect and identify security threats to industrial control systems, especially various threats received during the application process. Attacks can achieve intelligent analysis of industrial control system information, security assessment and accurate positioning of security events, and realize abnormal behavior detection of industrial control systems.
Description
technical field [0001] The invention relates to the technical field of industrial control systems, in particular to a method and system for detecting and identifying industrial control attacks based on zero dynamics. Background technique [0002] With the integration of industrialization and informationization, a large number of IT technologies have been introduced into industrial control systems. Industrial control system (Industry Control System, ICS, hereinafter referred to as industrial control system) is an application system that comprehensively uses electronics, information, computer and communication technologies to realize the automation of industrial production management processes. , gas and other basic fields have a very wide range of applications. Today, network equipment, computing equipment, operating systems, embedded platforms, etc. are commonplace in industrial control systems. However, there are still essential differences between industrial control syst...
