Axiomatic Design/Design Patterns Mashup: Part 2 (Cyber Security)

Part 1 established the theoretical framework for undertaking a top-down/bottom-up mash-up between the Axiomatic Design/Complexity Theory (AD/CT) and the Design Patterns (ÐP) framework. It synthesized an integrated N-model from the top-down V-Model and its antipodal/bottom-up Λ-model. Part 2 illustrates the approach in the domain of Cybersecurity. Recent trends in Cybersecurity indicates that our modern socio-technical systems are increasingly vulnerable to both external as well as internal threats. As the cost of defending our cyberstructures as well as the payoffs from successful attacks keeps rising, the cost of launching an attack simultaneously keeps decreasing. Cyber warfare is fundamentally asymmetric. Designing and managing modern socio-technical systems will demand greater appreciation for the language of threat-patterns and its defence. This paper applies the N-model to arrive at a generic pattern-language compositional technique using the Axiomatic Design Matrix. It then shows how one may splice the FR↔DP mappings with the FR↔ÐP mappings. Transcending the technical and into the socio, it is increasingly clear that wars of the future will be fought in the crucible of each individual human mind. Cognitive Biases are the patterns of weaknesses in this domain. The paper illustrates that patterns of cognitive biases can lead to patterns of cyber insecurity.
