Network Security Technology Applications In An Enterprise Network

Along with the extensive popularization and gradual deepening of computer network applications in the information age, complexity and changeability of network environment become increasingly prominent.In that case , computer network security will face huge challenges. The demanding of information security will be increased by enterprises also. It is a key that how to build a stable and secure network protection system in order to let enterprise information platform run smoothly. So the topic of applications and research of network security technology in the enterprise network is of important theoretical significance and realistic background.Firstly, backgrounds,purpose and theoretical meanings of applications and research of computer network security is introduced in this paper. Secondly,the article studies the basic concepts of network security from various aspects, it pointed out that security is an important precondition for enterprise network to run well. The goal of network security is to ensure that information in the network will not be removed, Leakaged and damaged.And it will enhance controllability and confidentiality of network system application.Therefore,it is important to establish a good network security system. It will protect important data in the enterprise effectively,and it make network run better.Then this paper studies the key technologies of information security and security protocols. Now advanced network security technologies include firewall technology, virtual LAN (VLAN) technology, intrusion detection and prevention technology,virtual private network (VPN) technology and computer virus prevention technology etc. This paper describe the conception,type, principle and function feature of the key technologies of network security detaily.Then layer two tunneling security protocol(L2TP), network layer protocol suite(IPSec) and SSL secure transmission protocol is introduced in the article.From these comprehensive application of research results,the paper describes the structure of network topology and the feature of business applications of my company. Then this article focuses on analysis of the existent network security risks and system security requirements. Finally, this paper designs advanced,scientific,and reasonable network security solutions from many aspects i.e. physical security scheme design , network platform security scheme design, application security scheme design and security management scheme design.The network security solution has been deployed for one year.After testing and operating,it is proved that the solution meet my company's needs of network security. The scheme is reliable and feasible, it achieves network security objectives, and the expected effect of our company. Finally, it also improves the operational efficiency of enterprises greatly.
