Key Technology Research Of Provincial Meteorologicalnetwork Security Management

With the rapid development of modern information technology, information is playing an increasingly important role on the national economy .with technological advances, there has been a series of network applications, network security, network control and network management problems. Therefore, how the network structure from the initial design and deployment of application services to start and build a superior performance, security and stability, expansion and strong, easy to manage the network has become a subject of concern of many workers in the network.In order to solve the Shanghai Meteorological Bureau in the network structure, network security problems, we rebuild the network system and strength the network security. The network structure was planed by subnet division technology. Multi defensive lines were set up to prevent the potential internal and external attack. The network security system was set up by virtual private network (VPN) technology, virtual local area net work (VLAN) technology, Symantec Antivirus software, Web Protect software, firewall technology, physics isolation technology and so on. The results indicated that network security could be safe guarded, and network corresponding quality was obviously enhanced. The safe, flexible, speed local network came true...
