关于WINDOWS个人入侵检测的研究 摘 要 入侵检测系统（IDS）可以对系统或网络资源进行实时检测，及时发现闯入系统或网络的入侵者，也可预防合法用户对资源的误操作。本论文从入侵检测的基本理论和入侵检测中的关键技术出发,主要研究了一个简单的基于网络的windows平台上的个人入侵检测系统的实现(PIDS，Personal Intrusion Detection System)。。Implementation of Personal Intrusion Detection System Abstract The Intrusion Detection System (IDS) can detect the system or the network resources on the real-time, discover the intruder who intends to enter into a system or a network without warrant in time and prevent users from wrong operation. Based on the basic theory of the intrusion detection and the core technology of intrusion detection, a way of the realization of a simple Personal Intrusion Detection System (PIDS), which based on Windows platform, is well researched. The current security status of the network is analyzed firstly, and then the history of intrusion detection technology and the current core theory of the intrusion detection system are introduced. At last, the network architecture on Windows as well as the structure of capturing and filtering data packets by Winpcap, a tool on development is introduced. After that, the system is realized under the Winpcap system environment. The abnormal detection technology is used in the system. After catching data packets with Winpcap in real-time, extracting probabilistic information about events from the intercepted IP packets and sending them to the intrusion detection module, information is analyzed by method of quantitative analysis. In actual system testing, the system shows a good ability on detecting the quantitative characteristics of network intrusion. Finally, the existed problems and our suggestion during this stage is summed up and according to the function of the system, the proposition is given about the future direction.
