Problems solved by technology

[0004] In view of this, the embodiment of the present invention provides a node vulnerability scanning method, device and computer equipment to solve the problem that the existing vulnerability scanning method adopts the same scanning strategy for each node in the power system, resulting in the scanning of the smart grid industrial control system. Overburdened and high-risk devices lack adequate levels of security protection and are more vulnerable to attacks from the public Internet

Abstract

The invention discloses a node vulnerability scanning method and device and computer equipment. The method comprises the steps: obtaining the vulnerability information of an industrial control system, the vulnerability scanning information of a target industrial control system, and the network topology information of the target industrial control system; according to the vulnerability information of the industrial control system, the vulnerability scanning information of the target industrial control system and the network topology information of the target industrial control system, generating a target attack graph, wherein the target attack graph is used for representing attack path information between nodes in the target industrial control system; according to the target attack graph, calculating a vulnerability risk level of each node in the target industrial control system; and determining a vulnerability scanning strategy of the target system according to the vulnerability risk level of each node. Through the implementation of the invention, a higher security protection level can be provided for nodes with high risk levels, and the overall security of the system is improved; scanning of low-risk-level nodes is reduced, system resources are saved, and influences on normal operation of the system are reduced.

Description

technical field [0001] The invention relates to the field of security protection of smart grid industrial control systems, in particular to a node vulnerability scanning method, device and computer equipment. Background technique [0002] The power industry is an important basic energy industry related to national economic development and social stability, and is the core of national infrastructure. The power industrial control system is a typical industrial control system (ICS), which is an automatic control system composed of computers and industrial control components. When applied to smart grid scenarios, the power industrial control system has high security requirements; The application of Internet technology in the power industrial control system breaks its original relative closure, and the connection with the public Internet is getting closer and closer, and it is also more vulnerable to attacks from the Internet. Therefore, there are many security loopholes in the ...
