For intrusion pattern based signature detection, an improved quick multi-pattern matching algorithm is adopted, which can search for multiple patterns by scanning the packet once.
对基于入侵模式的特征，采用了一种改进的快速多模式匹配算法可以一次在包的负载中查找多个入侵模式。

In the system, apply the Intrusion detection technique of the based on unusual behavior and signature-based, and adopt the way of host and network configuration cooperating each other.
