写设计模式解析的目的其实是想把GoF的《设计模式》进行简化，变得容易理解和接受。GoF的《设计模式》是圣经，但是同时因为《设计模式》一书是4位博士的作品，并且主要是基于Erich的博士论文，博士的特色我觉得最大的就是抽象，将一个具体的问题抽象到一般，形成理论。因此GoF的这本圣经在很多地方用语都比较精简和抽象，读过的可能都有一种确实是博士写出来的东西的感觉。抽象的好处是能够提供指导性的意见和建议，其瑕疵就是不容易为新手所理解和掌握

The Internet and computer networks are exposed to an increasing number of security threats. With new types of attacks appearing continually, developing flexible and adaptive security oriented approaches is a severe challenge. In this context, anomaly-based network intrusion detection techniques are a valuable technology to protect target systems and networks against malicious activities. However, despite the variety of such methods described in the literature in recent years, security tools incorporating anomaly detection functionalities are just starting to appear, and several important problems remain to be solved. This paper begins with a review of the most well-known anomaly-based intrusion detection techniques. Then, available platforms, systems under development and research projects in the area are presented. Finally, we outline the main challenges to be dealt with for the wide scale deployment of anomaly-based intrusion detectors, with special emphasis on assessment issues.
