Chengdu Rural Credit Cooperatives, Integrated Business Systems, Network Security Solutions Are Designed

The entire's background is based on the network reconstruction of the integrated service system of Chengdu Rural Credit Union (CDRCU). To some extent, the problem of the network and information security can be solved by building up the network security system of CDRCU. The primary work finished includes: (1) pointing out the network security of the original system through the analysis of the original network construction, and proposing the need of the network security of CDRCU information system. (2) Clarifying the basic foundations and methods in the use of the engineering design and implementation according to the basic concept, security goal, security system, and strategy of the network security. (3) Putting forward the general design ideas, principles, aims, basic methods and elements of the security design of the information system by combining the reality of the CDRCU's network security. (4) Based on the design principles above, I also has described in detail the network architecture, the general security design, the design of the security partition, of VLAN addressing, of firewall, of the intrusion detection and of the anti-virus. Making a suggestion that security partitions must be done by the technology of the virtual firewall, confirming the logical network border and defining the security strategy and the data flow in each security partition. In the meanwhile, combined with VLAN addressing, IDS planning, and anti-virus protecting, the system's general security design can be fulfilled. (5) According to the design scheme, some specific measures are executed, which include the main capability guide line, the execution of the Logical partition of the host sever, the execution of the virtual firewall, of the addressing WAN and of the router. (6) Analyzing the re-constructed network security of the information system, pointing out the potential risks and solutions, and illustrating the next direction and preparation for the next network security of the information system.My design project is based on the real requirements and technical practice of the network security of CDRCU. Up till now, the project has been accomplished successfully. It will make great sense to establish the network platform and implement the network security strategy in the process of the update of the integrated business.
