Research on Computer Network Security Framework Based on Concurrent Data Detection and Security Modelling

Abstract

A formal modeling language MCD for concurrent systems is proposed, and its syntax, semantics and formal definitions are given. MCD uses modules as basic components, and that the detection rules are not perfect, resulting in packets that do not belong to intrusion attacks being misjudged as attacks, respectively. Then the data detection algorithm based on MCD concurrency model protects hidden computer viruses and security threats, and the efficiency is increased by 7.5% Finally, the computer network security protection system is researched based on security modeling.
