Abstract:
Critical infrastructure systems have recently become more vulnerable to attacks on their data systems through internet connectivity. If an attacker is successful in breaching a system’s defenses, it is imperative that operations are restored to the system as quickly as possible. This research focuses on damage assessment and recovery following an attack. We review work done in both database protection and critical infrastructure protection and establish our own definitions of how damage affects the relationships between data and software. Then, we propose a model using a graph construction to show the cascading effects within a system after an attack. We also present an algorithm that uses our graph to compute an optimal recovery plan that prioritizes the most important damaged components first so that the vital modules of the system become functional as soon as possible. This allows for the most critical operations of a system to resume while recovery for less important components is still being performed. Lastly, we show results from simulations using our algorithm on data graphs with various parameters.
