Towards a Networks-of-Networks Framework for Cyber Security

Networks-of-Networks (NoN) is a graph-theoretic model of interdependent networks that have distinct dynamics at each network (layer). By adding special edges to represent relationships between nodes in different layers, NoN provides a unified mechanism to study interdependent systems intertwined in a complex relationship. While NoN based models have been proposed for cyber-physical systems, In this paper, the authors build towards a three-layered NoN model for an enterprise cyber system. Each layer captures a different facet of a cyber system. They present in-depth discussion for four major graph theoretic applications to demonstrate how the three-layered NoN model can be leveraged for continuous system monitoring and mission assurance.
