Research on Quantitative Assessment of Cyberspace Security Status, Based on AHP and Optimized ERM Mix Algorithm

Abstract

Since the concept of Cyberspace is becoming more important, the traditional security assessment that mainly aimed at the quantity and details of threats is not enough. Especially with the rapid growth of the scale of cyberspace, there should be a assessment method to cover both overall and detail vision. To meet the need, this paper put forwards a holistic trend oriented quantitative assessment system of cyberspace security status. The quantitative assessment process combines the traditional AHP and an Optimized method of ERM together to determine the weight values. The combination algorithm improves the bad performance of AHP under huge matrices situation, and also revises the result of ERM when the dispersion differs, so as to make the quantitative assessment more efficient, feasible and accurate.
