An Immune Danger Theory Inspired Model for Network Security Threat Awareness

Within immunology, the danger theory is changing the traditional thinking ways of self/non-self discrimination. In this paper, an immune danger theory inspired model for network security threat awareness, referred to as NSTAidt, is proposed. After introducing the main idea of immune danger theory, the model architecture and the formal definitions are described in detail. Following that, with the network intrusion detection and danger signal computation method illustrated, the principle of network security threat awareness of NSTAidt is given. Theoretical analysis shows that NSTAidt is feasible. Thus, it provides a good solution to computer network situation awareness.
