Abstract


In modern life, network overwhelms the worldwide as far as it can. More people can not work without net, also live and study. As the organization of enterprise and the office of school build their own inner network one after another to live and work efficiently, all kinds of problem come along with it, such as virus, illegal access and rubbish mail etc. The situation even make worse when inner employee establish game and file transfer server, and some build private web site. These illegal intranet services not only bring about security thread, for example, secret betrayed, virus spread etc, but also disturb normal network service for engrossing the bandwidth. Intranet service audit system is designed to resolve this problem.Intranet service audit system is a new thesis which upgrades strategically service audit to a higher position and puts the abuse of bandwidth into reserch. This thesis belongs to the theme of active defense. In this thesis, user configurtes parametor firstly, then the system actively finds and locates the illegal services, the alarm information and audit information will be provided in logs. This subject is the same theme of active defense as vulnerabilities scanner, but former puts emphasize on service audit, the latter lays importance on vulnerabilities scan. Though they are different, intranet service audit system makes full use of the method in sign-code exploration and the structure style of sign-code warehouse. The former also absorbs other network technology which is highly researched before, like multithread technology, port scan technology and detective technology. The functional module and system frame of security audit system is also as reference when designed. The simple and convenient configuration of Symantec Antivirus client and other net scanner is another point which is used for reference in the user interface design.Intranet service audit system adopts the technology of object-oriented design. Firstly it analyses the need of user, then builds the model and structure, and puts it into realization. After finishes the job, test is carried out. Test result indicates this system can work rightly to supervise intranet service, include finding and locating illegal one. For many vulnerabilities being hidden in the illegal intranet service, Intranet service audit system can diminish threat coming from the inner network, also it can prevent the limited bandwidth being used by game players. Therefore, this tool can keep the network working in normal.
