CARDINAL-E: AIS Extensions to CARDINAL for Decentralised Self-Organisation for Network Security

This paper extends the CARDINAL architecture by Kim et al. (2005) to CARDINAL-E. CARDINAL-E keeps the innate immune system behaviour at every computer on the network and relocates the adaptive immune system behaviour to higher performance computers. Two paradigmatic shifts are achieved by this modification. First is the shift from standalone to supportive, otherwise considered as architecturally static to dynamic. This leads to an additional layer of homeostasis at a network-wide level. The intended effect is to leverage unused capacity on networks of heterogeneous machines. Secondly, the change represents a subtle granular shift from “each computer has identical immune system components” to “the network (as a whole) carries all the immune system components”. This is a synthetic network-wide “body” where organs (CARDINAL’s Periphery and Lymph Node components) are finite and proportionate in quantity, and evolve their behaviour over time.
