It interconnects with the LANs of the National Bureau's subordinate body through tobacco satellite network and common network, so that build up the WAN of tobacco trade. So, security problems of the National Bureau LAN will affect the production, management and other facets of the whole trade.Based on the information construction master plan of tobacco trade, related architecture of information security standard and laws and regularity in point in China, this thesis presents an omni faceted project of the National Bureau LAN's security architecture, security management policy, security protect and security execution. The project analyses current conditions and security requirement of the National Bureau's network, and it confirms to requirement of practical applications and future demand. The project has been demonstrated by experts in this field and put in execution.The author of the paper is one of the major designers of the National Tobacco monopoly Bureau computer network, who engaged in the whole procedure of the project including demonstrability, design and execution.
