摘要：To enhance the electric power information network’s defensive capability for all kinds of security threats, this paper builds a risk assessment model for information network based on the Set Pair Analysis (SPA) comprehensive evaluation. On the basis of SPA theory, the information network’s index and the index of ISO/IEC27005 were formed as a set pair. The model introduced the improved AHP to determine the weight of each index, and extended the Spa’s three-Yuan connection degree to five-Yuan, which considered synthetically to the risk’s certain and uncertain factors. By calculating the connection degree, it can determine the risk value and level. Set pair situation was used to discuss the risk development trend. From practical calculation and the comparison with other assessment algorithm, the model appears simple and reasonable, and the calculation is objective and stable.
