Biologically Inspired Security attacks and Defences in the Data plane of Networks

The demand for anytime, anywhere, anyhow communications in future generation networks necessitates a paradigm shift from independent network services into a more harmonized system. This can be accomplished by integrating existing and emerging access networks via a common Internet Protocol (IP) based platform. Such a heterogeneous network is no more confined to its originating network domain, but can easily be propagated to other access networks. To address these security concerns, this paper proposes a biologically inspired security framework that governs the cooperation among networks to identify security attacks, and to inhibit attacks propagation in the heterogeneous network. The proposed framework incorporates two principal security components, in the form of anomaly detection framework and security control framework. The human immune system (HIS) and epidemiology have been adopted into the proposed security framework. Performance evaluation demonstrates the efficiency of the proposed biologically inspired security framework in detecting malicious anomalies such as denial-ofservice (DoS), distributed DoS (DDoS), and worms, as well as restricting their propagations in the heterogeneous network. Keywords— Heterogeneous network security, biologically inspired security, danger theory, epidemiology.
