Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The present invention expresses the function as a target-means hierarchical structure by analyzing the function of the process system in a hierarchical structure. This hierarchical analysis starts from the top-level function, and decomposes the top-level function step by step into the process system that realizes the function, the sub-functions of the process system, and finally decomposes into the underlying process equipment that realizes the function, so as to obtain the function-sub-function-equipment level relationship. Then, by studying the interactive relationship between the digital industrial control system and the controlled process equipment, a collection of process equipment and associated digital industrial con...

Abstract

The invention discloses an industrial control network security influence analysis method based on function analysis. The method comprises the steps: performing function hierarchical modeling and function decomposition; constructing a function tree topological graph; performing asset collection and analysis, and performing function and equipment association; analyzing a network security attack; evaluating the influence of functional consequences; generating a function topological graph, and establishing the hierarchical relationship from functions to equipment, thereby achieving the objective quantification of equipment information security importance; and analyzing the final actual influence of the information security attack on the process system and the path of the influence of the information security attack on the process system, so the objective quantification of the information security risk degree is realized.

Description

technical field [0001] The invention belongs to the field of network security, in particular to an industrial control network security impact analysis method based on function analysis. Background technique [0002] Since the Stuxnet worm attacked Iran's nuclear facilities in 2010, all walks of life at home and abroad have attached great importance to the information security of industrial control systems. Information security attacks will affect the availability, integrity, and confidentiality of software and data, adversely affect the operation of systems, networks, and related equipment, and pose a threat to industrial control systems. For information security attacks, how to intuitively understand the final impact of information security attacks on the process system is very important for system designers and system users. By studying the actual impact of digital devices affected by information security attacks on the entire system process, make Designers have a clearer...
