Abstract


With the rapid development of economic global, more and more Enterprises join the global competition by adopting advanced management information system, such as Enterprises Resource Planning (ERP). As a representative of the advanced Enterprise Management Information System, the ERP system could reduce produce cost, improve labor productivity and share the resource and so on. While enjoying the convenient of opening and freedom brought by the ERP system, we must face the challenge of information security.The security of ERP information management system was considered firstly when the small and medium enterprises implemented ERP system. The security of the information system generally included Data Integrity 、 Data Confidentiality 、 Authentication 、 Access Control 、 Non-repudiation and so on.The paper took the ERP system of "GuangDong FoShan Photo-Electricity Corporation" the author had anticipated and designed as an example. The paper studied particularly the system security in the following several aspects and designed the access control, identity acknowledgement and authentication and data secrecy. Verified for some time, the system security had made primary progress.1. To set forth the primary principle, management idea, frame system and function of the ERP system. Combining the development of computer technology, network technology and management technology, the paper summarized the conclusion of the development trend of the ERP system.2. To describe the definition and target of computer system security, and to discuss some important technology on computer security, including the RBAC (Role-Based Access Control)、 the Cryptology、 the VPN (Virtual Private Network)、 the firewall and the IDS (Intrusion Detection System ) technology and so on.3. To analyze the safety requirement and security of the ERP system. Especially, the security problems of ERP system based on the B/A/S(Browser/Application/Server) three-layer model were deeply researched and discussed. Finally. To analyze the ERP system project of FoShan Photo-Electricity corporation.4. Aimed at the safety problems existed in the ERP system of FoShan Photo-Electricity corporation , putting forward a security resolving project of the ERP system on the base of the RBAC technology and MD5 algorithm, which was realized by applying C++ Builder6.0 and SQL Server database.5. Aimed at the network safety problems existed in the ERP system, putting forward a safety model on the base of the VPN and the firewall technology, which provided ideas for further studying the safety problems of the ERP system.Finally, the conclusion was summarized and the developing trend was forecast.
