Design And Research Of Campus Network Security System In A Technical College

With the popularization of computer network and the maximum sharing of information resources,more and more attention has been paid to the construction of campus network in Colleges and universities.The construction of campus network can provide teachers,students and administrators with very convenient network services,but the campus network will often be subject to a variety of challenges,including the physical environment,computer viruses,management and maintenance Coerced.These unsafe factors will cause the loss,damage and modification of the user's data,resulting in system paralysis,unable to operate normally and other adverse consequences.Therefore,the design of a set of safe campus network construction scheme,to ensure the stable operation of the overall campus network,to meet the needs of teaching staff office,students' learning and life,has become the most fundamental goal of the current campus network construction.The main contents of this paper are as follows:1.This paper analyzes the research status of campus network security at home and abroad,introduces various key technologies to ensure campus network security,analyzes the campus network security in detail from the perspective of physical layer,network layer,system layer,application layer and management layer,and summarizes the requirements of user security,network platform,application environment and operation and maintenance management of campus network security.2.According to the current situation of the campus network in a technical college,this paper summarizes the requirements of the campus network security,designs the campus network security system,expounds the design principles and objectives of the campus network security system in the technical college,and makes a detailed analysis and design of the security system at all levels.3.Finally,the appropriate network security equipment is selected to build a technical platform for the campus network.Through VLAN division,user authentication,firewall technology and security management,the dual computer backup of the convergence layer data is realized,and the simplified model of the convergence layer of the platform is simulated and verified.In short,the work of this paper will provide some valuable reference for the construction of campus network security.
