In analyze the deficiency of traditional intrusion detection system, a new kind of intrusion detection method, which named EDID (An Intrusion Detection Method Based on Euclidean Distance) is put forward for reduce false positive rate.

• 在此基础上，将欧氏距离(Euclidean Distance)引入了入侵检测系统以降低入侵检测系统的误报率，并提出了基于Euclidean距离的入侵检测方法Intrusion Detection Based on Euclidean Distance(EDID)。
