Approach to intrusion detection model based on biological memory principles

The principles of memory storage,update and forget in biological memory were employed;a model of intrusion detection based on biological memory principles was established.In the model,the characteristics of fast attenuates and update and being sensitive to outside information of instantaneous memory were used to detect abnormal data promptly and prevent intrusion at an early time.The short-term and long-term memory can adjust memory intensity with anomalous accesses,and interconvert with each other that attempts to achieve maximum effect.The short-term memory capacity restricting and memory bank update automatic theory were used to save resources consumption of intrusion detection system so as to store important information by more space.An application shows that the model can track the latest development in real-time,selectively update or forget old data and make a prompt,efficient and precise judgment in virtue of the memory bank.
