357 Network Defense Efficiency Metric Model Based on Analytic Hierarchy Processing

For making more scientific and comprehensive quantitative measure on the security of the LAN, the method of measuring the defense performance with attack effect is proposed. Attack targets set whose elements include attack duration, control duration, interference duration, infection rates are proposed. And then based on the index set, a network defense performance model using analytic hierarchy process (AHP) method is presented. Simulation results show that the proposed measurement method and model can better measure the security of network protection systems.
