Design And Implementation Of Security System Of X Bureau Computer Network

Rapid development of IT has led human beings into an information society. The economic system more and more relies on information resources,information technology, and the information industry. In the information society, information has become a valuable resource, but security problems that come with the expansion of the Internet are increasingly serious and noticeable. Now network security is a vital strategic issue of national security.As the biggest state-owned enterprise,X Bureau has basically completed the construction of its large-scale intranet(DQnet) that supports sharing of internal information. The intranet covers a wide area, holds a large number of users, includes many complicated application systems, and needs high-level security. How to ensure confidentiality, authenticity, incontestability, and integrality of shared information is a practical and important subject. Setting up a security system for Dqnet is necessary so that the intranet can run smoothly and safely transfer all data for production activities.Theoretical researeh and analysis on information system security including important concepts related to information security , the features of information security and widely employed information security enhancement techniques are presented in details. Considering the practical requirement for information security in Dqnet, the author provides a framework for an information security system for oilfields like Daqing, and has developed several modules. In addition, interfaces and implementation methods of Web, Domino, etc. are analyzed in detail, the local and Whole solution for the SHAANXI has been proposed and implemented in some 1st. It HAS been proved that the work has great guidance on the further work.The thesis is concluded by discussions and conclusions that include what to be improved for the Data Processing center as well as suggestions on works on goverment information systems in long term .
