Research And Application Of Admission Control Technology In Procuratorial Intranet

In order to accelerate the application of information technology in the office of the procuratorial system,the procuratorial system has established a three-level network from the Supreme People’s Procuratorate to the basic-level prosecutors’ procuratorate’s internal local area network.The network has a large scale,wide coverage and many network access points.According to the unified arrangement of the higher-level prosecutors,although a county-level procuratorate has deployed a variety of network security protection measures such as firewalls and intrusion detection,network security problems caused by terminal computers still occur from time to time,mainly due to illegal users and terminal computers.Access,causing network security incidents such as the disclosure of confidential documents and the spread of viruses.Based on the actual needs of a county-level procuratorate’s internal LAN network security,this thesis studies the relevant technologies and principles of network access control,combined with actual needs,mainly selects the 802.1X protocol as the identity authentication technology for the internal LAN access control of the procuratorate,and designs The access control solution for the internal LAN of the procuratorate selected H3C’s EAD access control technology as the management platform for deployment and implementation.The solution achieved the expected goal and met the access control requirements of the internal LAN of a county-level procuratorate.The main contents are:1.In-depth understanding of the current network security status of a county-level procuratorate,based on the actual situation,conducted a demand analysis,and obtained network security issues that need to be resolved.2.Analyze the main network access control technologies,and determine that the user identity is authenticated by the CA digital certificate and 802.1X joint authentication,and the security status of the terminal computer is checked.3.From the four perspectives of users,terminal computers,application systems,and user use,a complete and comprehensive internal LAN security system of the procuratorate was designed to solve a series of problems in the actual use of the internal LAN of a county-level procuratorate.Network security issues.4.Deployment and implementation of authentication servers,access switches,and terminal computers.The core of the access control of the Procuratorate’s internal LAN is to ensure that the user’s identity is legal and that the terminal computer’s security meets the requirements.The access control solution designed and implemented in this thesis has achieved the expected purpose and solved the problem of the existing internal LAN user access Control,terminal computer security is difficult to guarantee and other issues,improve the security of the internal local area network and business application system of a county-level procuratorate.
