Zhen Wu · Zhongguo tiedao kexue · 2001
Based on the study fruits of information safety technique and theory at home and abroad, as per actual requirements of ticketing system and the practical application in the safety aspect of the system on China′s railway, this paper puts forward a new safety concept applicable to the ticketing system .The paper introduces the formation of safety system and of the ticketing system in detail and points out that the development trends to the latest network safety technique in the ticketing system. According to the network configuration of the ticketing system and the understanding of the information safety principle, the paper puts forward a set of safety protection system with the application system as the center. The new network security techniques and methods are adopted to build a protection system on four layers including network system, operating system, database system and application system. With dynamic detection and real time monitor, the four layers are combined organically to constitute a relatively integrated network security system. The whole security stratagem is the core of security system. Under the control of this whole security stratagem, different protection methods are used synthetically. In actual application of the system, in combination with strict security management system, the security stratagem is summarized and adjusted constantly and new techniques adopted to ensure the safe operation of the system.
