Embodiment Construction

[0026] A distribution automation terminal equipment information security risk assessment and calculation method, such as figure 1 shown, including the following steps:

[0027] Step 1. Use the analytic hierarchy process to conduct a comprehensive information security risk analysis on the software and hardware development and deployment environment and operation and maintenance environment of the power distribution terminal, and divide the information security risk of the power distribution terminal into system layer, communication layer and equipment configuration layer. Information security risk points at each layer.

[0028] The information security risk points of the system layer in the step 1 include: the operating system starts the WDB target proxy vulnerability, the bootline authentication information memory plaintext storage and the operating system remote overflow vulnerability; the communication layer information security risk points include: open telnet plaintext tra...

Abstract

The invention relates to a method for evaluating and calculating information security risks of distribution automation terminal equipment, and its technical characteristics include the following steps: Step 1. Using the analytic hierarchy process to conduct a comprehensive analysis of the software and hardware development and deployment environment and the operation and maintenance environment of the distribution terminal Information security risk analysis; step 2, building an experimental platform for power distribution terminal information security testing; step 3, conducting power distribution terminal information security risk testing and finding out power distribution terminal information security vulnerabilities; The calculation method quantifies the risk value of power distribution terminal equipment and judges the possible impact on the enterprise after the security vulnerability is exploited. The invention can provide a basic platform for the overall information security research of distribution automation terminal equipment, and can be used to guide the construction of information security protection capabilities of distribution automation systems, avoid system abnormal failures caused by hacker attacks, and improve the safe and reliable operation of distribution automation systems Level.

Description

technical field [0001] The invention belongs to the technical field of power grid industrial control, and in particular relates to a method for evaluating and calculating information security risks of power distribution automation terminal equipment. Background technique [0002] Driven by informatization, two seemingly irrelevant industries, industrial control systems and traditional information security, have intersected. Especially since the "Stuxnet" incident, information security of industrial control systems has attracted great attention from all countries. The industrial control system is related to various important infrastructures and the national economy and the people's livelihood, so its importance is self-evident. For a long time, the industrial control system has been considered as a relatively professional and closed information island, which maintains a relatively safe state. However, with the rapid networking and interconnection of industrial control system...
