The essential problem of KBOOA are acquirement and organization of knowledge about the application domain. First of all, we recognize objects according to their outside characteristics and build stable concepts structures. In this way, the attributes and behaviors of any objects are treated as objects as well. The concepts are organized in hierarchies, the concepts' semantics are demostrated in the form of conceptual graphs. As hierarchy structure has inheritance, the system has ability to recognize and reuse concepts, analyze and reason the acquired information according to the existing knowledge, understand the problem space and present the system's functions and characteristics to the analysts and users in the form of scenarios. The main means of transforming informal requirements to formal ones is to recognize objects according to their outside characteristics, recognize attributes according to their functional dependence and describe the semantics of objects, behavior and attribute's relationship's because there is a automatic map from the descriptions of attributes and behaviors to class structures. It is difficult to transfer from OOA to OOD, We disscussed the modularity of Object-Oriented programs according to the principles of software engineering and presented the methods to decrease couplings and increase cohesions, i.
KBOOA以知识的获取、组织为中心问题,首先依据对象的外特性识别对象,并将属性和行为也作为对象处理,从而建立起较稳定的概念结构;KBOOA以层次的方法组织概念,以概念图的形式描述概念的语义,利用层次结构的继承特性,使系统具有识别、重用概念的能力,根据已有知识对系统所获信息进行分析、推理,产生对问题空间的理解,并以想定的形式向分析师、用户展示系统功能、性能,从而构成了一个交互式的,具有一定智能的需求分析环境;依据外特性识别对象,依据函数依赖关系识别属性,用概念图描述对象、行为及属性关联,是将需求由非形式化形式向形式化形式转换的主要手段,使属性及行为描述可向类型结构自动映射,为提高需求分析的自动化程度提供了依据。

At the same time, the anti-attack ability of the system is also improved. Even if some analysis module cannot work, it does not affect other modules. The packet capture module is the base of entire system. At present, most NIDS develop their packet capture module based on libpcap library whose windows edition is winpcap. Allowing for capturing efficiency and self-determined intellectual property and cooperation of each module, we program protocol driver to capture packets. By following methods such as filter in driver and decrease packet copies between user mode and kernel mode, we enhance the capturing efficiency.
网络数据包采集模块是整个系统高效工作的基础,目前国内外的大多数网络入侵检测系统的数据采集模块,都是利用libpcap提供的函数库来实现,其在Windows下的版本为winpcap,考虑到采集效率、自主知识产权、采集模块与系统其他模块的配合等因素,我们采用自己编写协议驱动程序来采集数据包,并通过在驱动程序中实施过滤、减少数据包在用户态空间和核心态空间之间拷贝的次数等方法,提高采集的效率。
