Design And Practice Of Network Security In Tobacco Processing Factory

With the help of the rapid development of the network, the sharing of the information and resource became easier and easier, the operating costs of the enterprise became lower and lower, the traditional mode of work also changed. The Centralized and static network security system unable to provide enough services to the enterprise as the Intranet and the contact with the outside grew huger. The importance of a safe and reliable enterprise network security system is more obvious.Firstly, this dissertation expounds the problems in network information security, researches the factors which impact the security of network and introduced the recent network security technology. According to the situation of Huahuan International Tobacco companies, the upgrade and status of enterprise network system and the problems after the update are studied. After these researches a safety strategy of the network system is raised. By the advanced security technology of the network (such as firewall technology, IDS, VPN, etc.) and the safety design concept, the security of upgrading work is designed.Based on the system environment and its applications, a solution is presented by the architecture technology. Consider the security require of system upgrade, the security services are provided in every protocol stack layer. The security require of the system is fully analyzed in the system updating design. The system is realized by the corresponding security technology with the guiding of safety strategy.
