Research Of Enterprise Information Center System Security

eCenter is an open platform for information construct of small business. It can supply the network services and application functions which are in common used. With the fast development of computer network on kinds of business, network security is attached great importance to by more and more people. It plays a more significant role in maintaining the normal network' working, and has become an important characteristic of the contemporary information society. Among many ways, firewall is the most effectual one. The OS of eCenter is an embedded system in the flash ROM, it can make the eCenter work better. The paper elaborates the principle of Internet firewall and how to design and implement firewall based on embedded Linux. Firewall mechanism is one of the important methods to protect the security of the network nowadays. The paper introduces the principle and tools of firewall based on Linux. Then it studies the technology, performance and application of Netfilter. It also introduces the concept and the development of the embedded system, and points out the advantages of the Linux application in embedded system. Then it researches the structure and implement of Linux embedded system. The last, the paper designs a suit of security tactic to insure the security of eCenter. The security tactic contains preventing network attack, choosing service starting and encrypting system. Certainly, the design and actualize of firewall is the most important thing. In this paper, we present a novel firewall, many new advanced firewall technologies are integrated in it.
