摘要
The communication mechanism plays an important role in an intrusion detection system, while it has not been paid enough attention. Based on analyzing the actual facts and expatiating upon the requirements a communication mechanism needs to meet, a message driven communication mechanism is proposed in this paper. The protocol presented here is divided into three layers： entity level, host level, and network level. The communication processes are also designed in detail. Experiments illustrate that cooperative entities can detect distributed sophisticated attacks accurately. Furthermore, this mechanism has the advantages like high reliability, low time delay and expenses.
