Abstract

Cyberspace has become a complex continuum spanning a variety of network technologies and domains, such as cloud, fog and edge infrastructures, and wired, wireless and mobile networks. It enables a ubiquitous interconnection of heterogeneous devices, such as traditional hosts; smart, internet of things (IoT), wearable, and mobile devices; as well as individuals and organizations. This results in pervasive collection and use of sensitive data. Such a heterogeneous and sophisticated mix of technologies, devices and people inevitably poses significant challenges both for the security of connected devices and systems, and the privacy of individuals and organizations that they interact with, as new reconnaissance techniques and attacks are released on a daily basis. The situation for systems which include smart devices is further aggravated by a multitude of actors, such as manufacturers, service providers, app developers, telcos, and proprietary Software-asa- Service (SaaS) deployments, in addition to the global nature of the cyberspace spanning over varying and potentially incompatible legislation.
