Abstract
In this work, we draft a methodology to build a cyber-security digital twin of a Smart Grid, starting from its architectural blueprint. The idea of a digital twin is not new and has recently been proposed as a means to enable simulations for the purpose of environmental protection where tests on the real system are difficult or expensive. The novelty in our work is in proposing and analyzing the possibility to dynamically align the digital twin with its real counterpart. As a preliminary step toward the synthesis of a Digital Twin for the Smart Grid, we propose the adoption of an architectural view that gets dynamically aligned with the state of the world at deploy and operation time. In this manner, we lay out the basis for a maintenance-aware model, which is at the core of the “digital twin” concept. The availability of a digital twin allows the enforcement of policies for the devices when they connect to the Grid. This paves the way for a Zero Trust Architecture (ZTA), as introduced in this work.
