HTTP Proxy Analysis And Research Based On The Security Gateway

Internet is a kind of open and standard technology which faces to all users, its resource shares through the network. But with the network being larger and larger to open more and more, a lot of sensitive information and restricted data of network take the initiative with attacking artificially passive various, for example information is revealed, the addition and deletion of the data and virus of distorting, computer are infected etc..The military network is facing challenges because of a high drgree of confidentiality requirements.In order to improve the security of the computer network, the relevant personnel has developed many kinds of network security technology. The HTTP proxy gateway technology is one of them. This paper introduces a HTTP proxy based on the military authorities in the local area network set up with the military network security gateway between the development process, its purpose is to build a Safe military network, thereby enhancing the security of military networks, security and network access controllable. The system adopts Visual Studio.Net as the developing platform, and C# as the mainly developing language, and uses Microsoft SQL Server relational database technology.The system can effectively carry on the HTTP proxy serveies, and also realizes certain safety control.Apply the HTTP proxy gateway in the network, not only can cause military LAN network user to have to visit military networks through the proxy gateway, to share network resources, moreover the website filtration mechanism of the proxy gateway can effectively limit user to visit some unsafe websites, protecting the user’s information, it thus can make the intranet user use the network more safely and can effectively carry on the basic network monitor and network management.In view of the confidentiality requirements of the military network, the paper application from the current Internet security problems, analyzes the HTTP proxy of the basic principles of security gateway systems and technology constitute, built on this basis, the proxy gateway security model, design and development of the HTTP proxy security gateway system, by analyzing the running results, draw conclusions and to finalize the set up on the military network security gateway platform HTTP proxy implementation of system functions. The paper is divided into six chapters:The chapter 1 describes the HTTP proxy security gateway system and the current WEB development background and problems, proposed solutions, analyze the security gateway HTTP proxy key technology and implementation methods.The chapter 2 describes the HTTP proxy security gateway system, key technology, a brief overview of proxy servers and firewalls, gateways relationship..The chapters 3 describes the model of the system design and development process.The chapter 4 of this paper describes the implementation process of system design, system implementation details about the specific operation. Finally, the system’s core processes were explained and instructions, and summarizes some debugging experience.The chapters 5 Comprehensive analysis of the HTTP proxy security gateway system is running the results of the basic functions of the system already has achieved the desired objectives of the system.The chapter 6 summarizes the main research work carried out to explain the lack of papers and thesis research for future development.
