Shortfall-Based Optimal Security Provisioning for Internet of Things

We present a formal method for computing the bestsecurity provisioning for Internet of Things (IoT) scenarios characterizedby a high degree of mobility. The security infrastructureis intended as a security resource allocation plan, computedas the solution of an optimization problem that minimizes therisk of having IoT devices not monitored by any resource. Weemploy the shortfall as a risk measure, a concept mostly usedin the economics, and adapt it to our scenario. We show how tocompute and evaluate an allocation plan, and how such securitysolutions address the continuous topology changes that affect anIoT environment.
