Distributed Quantitative Assessment Model for Network Risk Based on Immune

Artificial immune technology was applied to network risk assessment technology and a distributed quantitative evaluation model for network risk based on immune was proposed.According to corresponding relation between the changes of antibody concentration of biological immune system and the invasion of strength of pathogens,the model makes real-time and quantitative analysis on the current safety situation of network to effectively relieve the damage generated by network on the system attack and improve the emergency security ability of network information system.The experimental results show that the system can adjust the network security policy timely and effectively and offer the more comprehensive security,which is a better solution to solve network security.
