The Internet of Things (IoT) has been one of the key disruptive technologies over the last few years, with its promise of optimizing and automating current manual tasks and evolving existing services. However, the increasing adoption of IoT devices both in industries and personal environments has exposed businesses and consumers to a number of security threats, such as Distributed Denial of Service (DDoS) attacks. Along the way, Fog computing was born. A novel paradigm that aims at bridging the gap between IoT and Cloud computing, providing a number of benefits, including security. In this paper, we present ANTIBIOTIC 2.0, an anti-malware that relies upon Fog computing to secure IoT devices and to overcome the main issues of its predecessor (ANTIBIOTIC 1.0). In particular, we discuss the design and implementation of the system, including possible models for deployment, security assumptions, interaction among system components, and possible modes of operation.
