Research And Application On Secure Technology Of Computer Information System

With the development of the information technology, computer information system has played an important role in modern society. As long as any break appears in computer information system, it takes a huge effect in whole society. There is an important , direct and realistic significance in research about computer system security.The secure policy on application of the computer information system, the secure principle, secure layer, secure service and secure architecture model of the development of computer information system are mainly studyed on this thesis. The developing situation both home and abroad about computer information system security is indroducecd in this thesis. The network security , database security, cipher technology,firewall technology are researched . The secure policy and measures on the application and development of the computer information system are analyzed . The system design, database design, main system module fuction on a science and research MIS as the instance are explained in detail about, which is built as a complicated secure information system according to the secure layer and architecture model of the computer information system .Besides, the optimization of application system and database system are deeply discussed . The conclusions are given at the end of the thesis .
