Towards an Artificial Immune System for Network Intrusion Detection: An Investigation of Dynamic Clonal Selection

One significant feature of artificial immune systems is their ability to adapt to continuously changing environments, dynamically learning the fluid patterns of ‘self’ and predicting new patterns of ‘non-self’. This paper introduces and investigates the behaviour of dynamiCS, a dynamic clonal selection algorithm, designed to have such properties of self-adaptation. The effects of three important system parameters: tolerisation period, activation threshold, and life span are explored. The abilities of dynamiCS to perform incremental learning on converged data, and to adapt to novel data are also demonstrated.
