Abstract:

Aiming at the lack of overall properties analysis, we propose a Monotonic Index Space Analysis Model (MISAM) and the sensitivity degree and correlation degree are analyzed based on this model. An index weight distribution method is proposed based on multistage sensitivity, a risk evaluation method is built, and the demand meeting degree is defined to measure the gap between the current system security state and assessor’s demand. The simulation results prove the effectiveness of the proposed model and methods.
