An Adaptive Modeling for Security Infrastructure Fault Response

Summary form only given. Based on analysis of inherent limitations in existing security response decision-making systems, a dynamic adaptive fault response model is presented. Several security fault levels were found, which comprise the basic level, equipment level and mechanism level. Fault damage cost is calculated using the analytic hierarchy process. The combination of security policy in the circumstance, a large number of false alarms will be filtered. It also will be lower deviation of the evaluation of the damage cost. Meanwhile, the model takes full account of the impact of different responses upon fault repair and normal operation. And response costs are presented through quantitative calculation. On this basis, the paper presents a comprehensive response decision of security fault in the three principles-the maximum and minimum principle, timeliness principle, acquiescence principle. These will make the best decision in different situations. The experiment results show that the proposed model has good adaptability, timeliness, cost-sensitiveness.
