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.
