Abstract

Internet of Things (IoT) systems are increasingly being deployed in the real world, but their security lags behind the state of the art of non-IoT systems. Moving Target Defense (MTD) is a cyberdefense paradigm that proposes to randomize components of systems, with the intention of thwarting cyberattacks that previously relied in the static nature of systems. Attackers are now constrained by time. MTD has been successfully implemented in conventional systems, but its use to improve IoT security is still lacking in the literature. Over the course of this thesis, we validated MTD as a cybersecurity paradigm suitable for IoT systems. We identified and synthesized existing MTD techniques for IoT using a systematic literature review method,and defined and used four novel entropy related metrics to measure MTD techniques qualitative properties. Secondly, we proposed a generic distributed MTD framework that allows the instantiation of concrete MTD strategies suitable for the constraints of...
