Computer Network Security Design And Research

For the purpose of to make use of information better,and to satisfy the need of processing exploded information,the computer network must be set up. Today,the computer network is the essential Infrastructure of management and management systems.With the advanced use of computer network, the network security become a very important section.This article analyzed all the factors which will infect the network and affect the network security, discussed the probability danger in each layer of OSLand propose that the core problem of security is the security of LAN.For LAN security, the article propose mat with the routing function of Operating System and the socket programing, the workstation of LAN can be separate from the network by dynamic route, and with the dynamic route, each workstation can connect or disconnect to the network controllably.
