Reactive defense mechanisms, such as intrusion detection systems, have made significant
efforts to secure a system or network for the last several decades. However, the nature of …

Context: Internet-of-Things (IoT) systems are increasingly deployed in the real world, but
their security lags behind the state of the art of non-IoT systems. Moving target defense …

Abstract Moving Target Defense (MTD) has emerged as a game changer to reverse the
asymmetric situation between attackers and defenders, and as one of the most effective …

Abstract Moving Target Defense (MTD) consists of applying system reconfiguration (eg, VM
migration, IP shuffling) to dynamically change the available attack surface. MTD makes use …

Represented by reactive security defense mechanisms, cyber defense possesses a static,
reactive, and deterministic nature, with overwhelmingly high costs to defend against ever …

Modeling a complete Internet of Things (IoT) infrastructure is crucial to assess its availability
and security characteristics. However, modern IoT infrastructures often consist of a complex …

Nowadays, as the cyber-threat landscape is evolving and digital assets are proliferating and
becoming more and more interconnected with the internet and heterogeneous devices, it is …

Moving Target Defense (MTD) has emerged as a newcomer into the asymmetric field of
attack and defense, and shuffling-based MTD has been regarded as one of the most …

We propose a suite of dynamic security metrics that timely, dynamically, and adaptively
assess the effectiveness of the software-defined network (SDN)-based moving target …

The correct and efficient measurement of security properties is key to the deployment of
effective cyberspace protection strategies. In this work, we propose GRAPH4, which is a …
