Abstract


The invasion (Intrusion) refers to the attempt to destroy the computer confidentiality, integrity, availability, or controllable range of activities. IDS (Intrusion Detection) is the collection and analysis of information critical node of the computer network and computer systems, to recognize and respond to the use of malicious behavior on the computer and network resources, detect whether there is a violation of security policy events or attack signs. It not only detects intrusion from outside, as well as the supervision of the internal activities of unauthorized users. General for intrusion detection software, hardware, collectively referred to as the intrusion detection system IDS (Intrusion Detection System). Intrusion detection is an important technology in the field of computer security, computer security a hot topic of theoretical research. In the past few years, the Chinese government has increased investment in intrusion detection research. In June 2000, 863 intrusion detection research in information security technology contingency plans. This paper presents a distributed mobile agent intrusion detection system, it will be network-based and host-based intrusion detection systems together, with a good distribution of performance and scalability. This work is mainly in the following aspects: the use of mobile agent technology to design a distributed intrusion detection system. Using a combination of protocol analysis and pattern matching methods, effectively reducing the matching range of the target, and to improve the detection speed. Improved matching algorithm, network engine with better real-time performance. CIDF (Common Intrusion Detection Framework) system architecture based on distributed three-tier architecture and two-step analysis of the structure design to ensure system scalability and adaptability. Encryption and authentication components to special CA certification system, to solve the intrusion detection system security issues. Chapter 1 and Chapter 2 describes the deficiencies of the existing security technologies and intrusion detection system development; CIDF model, the intrusion detection system works, system architecture, and classification, the lack of existing intrusion detection technology and trends. Chapter 3, Chapter 4 and Chapter 5 discusses the design of distributed intrusion detection system; method of attack classification as well as the the the intrusion rule language design and intrusion detection subsystem design. Chapter 6 discusses the Distributed Intrusion Detection System security problems and countermeasures; then pointed out that the characteristics of the system and the inadequacies and future work.
