Design And Implementation Of Security Domain Classification Protection System

In the twelfth five-year plan for the national promotion of information technology,the proposal are to be refined that vigorous promotion of the information applicationdrives industry and economy to grow and changes the extensive economy growthmode which results in great resource consumption. Thus, the strategic adjustment ofthe economic structure is to be accelerated. From national plan to enterprise practice,the increasing popularity of information has presented a significant push on enterprisedevelopment. However, viruses and network attack were brought up and enterpriseinformation work was confronted with far more severe security problems. Therefore,it’s essential to protect effectively an enterprise network information security.Combined with the author’s practical experience of network and securityconstructing work, this paper researched thoroughly on the theory of security domainand accomplished the strategy of divide and conquer in security domain as well as thedesign and plan of enterprise network. The security requirements and risks on physicalsecurity, access control, convergence security and the kernel security were analyzedand the weak points were found out. Then a security system of enterprise networkbased on the security domain classification was established throughanti-electromagnetic radiation, network control, diskless workstation, windowsdomains management, security audit and backup recovery etc.. Finally, the designedsecurity domain system was tested, validated and confirmed.The network security defense system is given by security domain classificationtechniques. It improves the protection ability, points out the essence, decreases thewaste of fund and resource caused by over protection. With this system, money arespent less while practical value proves highly worthy.
