Abstract

Cloud computing network and next-generation network is now widely used, which brings more security threats. Based on the process and the network tuples communication to construct defense system, the key technologies of defense under IPv4/IPv6 dual stack network are researched. It presents the NRLS Sunday based on improvement of the longest unique substring and Sunday algorithm, to avoid excessive repetitive character comparison and improve the matching efficiency of a single pattern string. Compared with BM, Sunday algorithm, the experiment shows the improved algorithm optimizes its time complexity. Under high-speed network, packet data contents is carried on rapid detection and analysis. Based on intelligent traffic restrictions for process and network, the intrusion detection and defense is conducted for network. In this paper, parallel packet detection method is studied under the high speed. Application web collaboration, and the unified arrangements and issued policies is applied in a complex network environment, proposing and realizing the effective method of defense in the complex network environment.
