Processing Technology And Network Security Charging Network

This article is about the designing and realizing of the PSTN on-line charging postmanaging system developed by Power Builder. PB is a tool that is mainly used in database application software and can support visual developing technology in the windows. It can be used in client/server structure and is adapted to developing database appellation programs. The C/S structure in the charging system uses three-layers model. The achievement of application logic layer by storage procedure strengthens greatly the abilities of application logic program's controlling data. The program in the client adopts a great deal of data windows and achieves managing works, including querying, grouping, statistics, reports, printing and so on, in many kinds of styles and skills. The connecting between the program developed by PB and SQL Server database is through the special database interface provided by PB that can support the circular nesting of cursors. This paper discusses the security about charging on the net in the charging system also. We introduce the describing of intrusion system on the net and analyze the flaws of three popular network operating system and attacking methods for these flaws and hidden troubles. We analyze the advantages and disadvantages of different intrusion- detection systems from different point of views and make general comparing for Knowledge-Based IDS and Behavior-Based IDS. At last we give a example of NN- Based IDS, including its detailed design diagram which kernel is the separator of NN and we make improving suggestions also,...
