Research On Security Management Technique And Method Of Intranet Host

Along with the rapid development of Internet, the enterprise network faces great challenge, and the problem of intranet information losses has become more and more serious. According to the relative organization statistics, most attacks comes from intranet, so it is very significant to ensure the security of intranet.After researching the situations of intranet security, a intranet host security management system was designed, which ensures the safety of the host through identity authentication and access control. Firstly, through adding some security measures to Radius authentication technology, a security authentication model which realizes the legitimate validation of host users, has been established. Secondly, the IDH-RBAC, a new access control model based on RBAC has been built to control the privileges of legitimate users.Thirdly, every access control has been realized through buliding models and using some special technologies. Lastly, experiment situation has been bulit to test every function module. The experimental result shows that the host security management system has met the security requirements of Network Management System, and guaranteed the host safety.
