This paper describes a model of immune intrusion detection in which an independent form is introduced in. Immune intrusion detection receives the vaccine signal to control the Vaccine Module in real-time signal processing. Vaccine extraction signal is that extract from one memory detector set with antibodies to mature vaccine set and vaccination signal is that vaccinated other mature detectors which need vaccination. The objective of this model is to share antibodies (detectors), establish communication links between different detectors increase the flexibility of detectors and improve the overall detection ability of detectors. Through the simulation by MATLBE, it proves this model has greater comprehensive detection performance.
