Electric power communication backbone data network security comprehensive evaluation method based on AHP-RST

Abstract

The invention discloses a power communication backbone data network security comprehensive evaluation method based on AHP-RST. The method aims at solving the problems that evaluation indexes of an existing network security evaluation method are not meticulous enough, one-sided and lack of quantitative measurement, and evaluation content is subjective. According to the method, an analytic hierarchy process (AHP) and a rough set (RST) are adopted to calculate the weight of each index of an index layer and a criterion layer respectively, the optimal combination weight is solved, then a fuzzy relation matrix is combined with the weight of the network security index, and therefore a total fuzzy evaluation result is calculated. And finally, according to a maximum membership degree principle and a power communication backbone data network security level comment set, converting the fuzzy comprehensive evaluation result into a state level corresponding to the fuzzy comprehensive evaluation result. The method has the advantages that risk management and control on the power communication network are facilitated, and the problems of possible factor uncertainty and excessive dependence on subjective experience can be effectively solved, so that subjective and objective combined comprehensive evaluation is performed on the power communication backbone network data safety operation state.

Description

technical field [0001] The invention relates to the technical field of power communication and data network security, in particular to an AHP-RST-based comprehensive evaluation method for the security of a backbone data network of power communication. Background technique [0002] At present, there are few studies on the overall evaluation of communication network security performance at home and abroad. Some studies have considered multiple factors that affect the security of the communication network, such as reliability, invulnerability, and vulnerability, but they lack a systematic and overall analysis of the security identification level of the entire communication network operation, which needs to be improved. Relying on ISO / IEC1335 (this standard gives the general procedure for evaluating the security of power communication network), fully consider the high-risk factors at the economic and engineering levels, and use fuzzy evaluation to highlight the main aspects that...
