The Research On Information Network Security System Of City Land Forestry Resource

Whether forestry's information online security is a key factor of forestry's information construction success or not, it is the important foundation stone of forestry's information construction sustainable development. Most safe problems of neglect at the beginning of setting up of forestry computer network that our country is existing, have made considering being safe, has only set up the safe mechanism on the safe mechanism of physics too. What better strengthening the safety of forestry's information, need to carry on research to the city land information online security urgently.The information online security system of land forestry of the city regards forestry's information network of Guangzhou as the target of managing, means of information safety of utilizing 3S technology, encryption, technology of the database, safe transmission technology of data, etc. to offer, under the circumstances that the management objectives are restrained, have carried on the following research to forestry's information online security system in the land of Guangzhou.(1) The land information online security states of domestic and international city of thesis survey and serious consequence not enough to cause of online security. As guidance with sustainable theory, scientific theory of the system, informatics theory, management theory, economics theory, investigate Guangzhou city society economic, physical geography, urban forestry and current situation of information safety.(2) Use 3S technology, encryption, network technology of the computer, database technology, have pointed out forestry's information online security existing problem and opportunity and challenge faced. Have pointed out the application prospect of forestry's information network case study.(3) City informationization safe construction background as backing, expound the fact Guangzhou city city land network topological structure and data transmission state with Guangzhou.(4) Have proposed the research contents, method and technological route of forestry's information online security of land of Guangzhou.(5) Land forestry information online security set out from city, propose group network mode, basic principle, based on password technology online security tactics, forestry of information network, structure the overall tactics of online security of forestry's information of land of Guangzhou(6) Proceed from particularity of the urban forestry's information network, follow the module basic thinking, draw lessons from the method that the telecommunication online security uses, compare with the security framework of the land information network of other cities, combine forestry's information-based characteristic, according to the forestry bureau of the city, the tertiary regional systems of the forestry bureau of the county, forest farm to forestry's information network of land of Guangzhou, propose the system implementing scheme of the online security from system security, database security , data transmission security , cultivation and management of people(7) Ensure from the law, the system is ensured, assurance of organization, personnel's quality ensure the respect to describe the importance of the security...
