基于手持设备平台的入侵检测系统的研究

操作系统和型号的多样性给手持设备杀毒软件研发带来了诸多问题。鉴于手持设备操作系统的规模及内存容量的限制，丈中提出将Snort技术应用于手持设备安全领域。由于Snort是一个基于Libpcap的轻量级入侵检测系统，所以丈中所研究的用以增强手持设备信息安全的系统模型命名为轻量型手持设备入侵检测系统。限于手持设备平台的特殊性，在优化模式匹配算法与匹配规则相结合的基础上设计了系统模型。

Handheld Device Platform-based Intrusion Detection System

The variety of operation system and model has brought many problems to the development of antivirus software for handheld devices. According to the size and memory limitation of the handheld devices operation system, this paper suggests the application of Snort intrusion detection system technology in the information security of handheld devices. Because Libpcap-based Snort is a light-weight intrusion detection system, a light-weight handheld devices IDS is proposed so as to enhance the information security of handheld devices. Limited by the special nature of handheld platform, the system model is designed on the optimized pattern-matching algorithms and matching rules.
