Design And Implementation Of The Enterprises Intranet Network Terminal Security System

With the development of the modern internet technology and the promote of the consumer demand, the computer is used more widely. In order to improve office efficiency, the Intranet is used in many places, which makes the communication inside and outside becoming more convenient. However, with the advantages the internal office network brings, the unprecedented risk is also brought.The development of the terminal desktop security management technology can meets the enterprises IT security requirements of the office a certain extent. But the terminal desktop security management technology does not have a uniform standard, and the types of security product and service provided by multiple vendors with varying quality. So, how to improve the network security inside enterprises is still a topic worthy of further studying.Based on the backgroud, this article is going to study the design and implementation for enterprises of the internal network terminal security framework.The main contents are as follows:(1) Introduced the security threats in the current enterprises and institutions, including the terminal’s own vulnerabilities, threats of removable storage media and so on.(2)For the threats in front, collected the current typical coping strategies and analyzed the terminal security system deeply. Base on the search, the overall framework of security system is designed.(3) For the security system proposed before, proposed testing standards and testing methods, and executed the functional testing and performance testing of the safety system.The main innovation of this thesis is that proposed approach of terminal management and removable storage media management terminal integrated management, based on the previous study.(1) The management of personal terminalThere are a series of problems in the system with no terminal safety management, such as changes of IP address, and stealing of internal documents, and infection of virus, etc. All the problems can be solved efficiently by using personal terminal management approach.(2) Management of removable storage mediaUsing access controlling and auditing technical to make the removable storage media safety, the unauthorized media cannot be used in the enterprise and the files in the authorized media cannot be opened by unauthorized man out of the enterprise. Every operation on media will be recorded and managed and the illegal operations can be tracked and audited.
