Design And Establishment Of The Computer Network Security Management System In Vocational Colleges

The current international and domestic Internet have achieved rapid development,as an important infrastructure of vocational colleges, the campus computer networkplays important roles in teaching, scientific research, management and externalexchange and so on. As an open system accessible to teachers and students, there is asharp increase of data transmitting on the campus computer network, which is facedwith threat and attack from different sides.Based on the integral structure of the various functions of the campus computernetwork security management system, this paper analyzes how to realize eachfunction and what kinds of data model will be used in the management process; usesthe conventional network monitoring tools to establish network facilities such as buildrouters, switches and firewalls and so on to perform security management on theentire network; network management includes configuration management,performance management, fault management, security management, usermanagement, network monitoring and other functional management items. Thedevelopment of the entire system is very complex, involving various computer andnetwork technology. It is required to establish a campus computer network securitymanagement system based on SNMP, VLAN, firewall, identity authentication andIDS, so that the various functions needed by campus computer network securitymanagement can be achieved, including network monitoring, equipment management,user management and fault management and so on.
