Study And Designment Of Embedded Web Gateway's Security Based On Electric Power System

Computer security has become the most important issue to which was paid attention by countries and governments all over the world since Internet came forth. At present the step of informationization construction is increasingly going faster and stricter require with security technology. Along with the introduction of Gateway system and Embedded Internet technology to Electric Power System, it has the same security problems. Electric Power System is one of the infrastructures in our country whose security is concerned about normal society operation, so it is important how to ensure its security.Embedded Web-gateway has been applied in Electric Power System because it is smaller and doesn't need special client soft. But it attaches more importance to funtion than security. This is not enough to apply in Electric Power System. This paper works on it's security problems.During the process of analysis and design to EGSS, this paper makes the requirement analysis based on the electric system firstly. Further more, according to the analysis of embedded security system it makes the frame-design and mechanism-design. Finally, it discusses the EGSS's core detail-design. In the aspect of system design, this paper carries through the development on the basis of successful programming methods of embedded system. On how to choose security solutions, according to the analysis and contrast with current leading security technologies, this paper design a security solution with stateful-inspection, access-control and IDS. In detail-design this paper in detail explains and analyzes the stateful-inspection from its principles to implement.Finally, according to the requirements of embedded system testing, the testing and running platform is built, and the embedded security system is tested. Then scientific analysis of the security system performances is made based on the testing results. The results of test show that our solution is feasible.
