Recently,the popular technologies of protecting network include data-encrypting、firewall、IDS、killing-virus、access-controlling and so on.These technologies resist the security threatening from network in one aspect and some aspects respectively.However,the technologies of computer virus and hacker are also developed.In the building of the campus network,it is impossible to have the totally security.Using a lot of network security technologies to build a relatively safe network which satisfies the security request to certain extent is a wise way. After the discussing of several network security technologies,the security problem of the Campus Network of Yanbian University is analysed in detail.According to the real problem when the Campus Network is running and based on using the guidance of safe theory of information system,a overall security solution is put forward in this t
