Multi-level Network Security Access Control Method Based on SPEA-Ⅱ Algorithm
With the rapid development of current network technology,network security issues are increasingly prominent,espe-cially access control security.In order to solve threat detection accuracy and security access control in current network systems,a new network multi-level security access control method is proposed by introducing the SPEA-Ⅱ algorithm.This paper deeply analyzes the principle of network multi-level access control mechanism,clarifies the security access control objectives.Combined with the network boundary area,transmission channel area and mobile terminal equipment area,boundary access control objective function,security threat detection objective function and user identity authentication objective function,the security threat detection accuracy of the net-work system is improved.The SPEA-Ⅱ algorithm is used to solve the joint objective function,and obtain the best scheme of network multi-level security access control mechanism.The approximate optimal solution set is gradually approached by the iteration,the opti-mal security policy combination is established,and the attack traffic factor is calculated to complete the multi-level security access con-trol of the network.Experimental results show that the detection accuracy of the proposed method is 94％and the security assessment is 0.96.This proves that the proposed method has good multi-level network security access control effect,it has strong security and adaptability,and can provide technical support for network security strategy in the field of China mobile internet.
