Abstract: In terms of advanced network security technology and equipment,how to rebuild the network system and to strengthen the network security was brought forward according to the existing problems and the hidden trouble of local network structure and network security in Dalian Meteorological Bureau.The network structure was replanned 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,WebProtect software,firewall technology,physics isolation technology and so on.The results indicated that network security could be safeguarded,and network corresponding quality was obviously enhanced.The safe,flexible,speed local network came true.
