Cyberspace is far more than merely the Internet. All devices reachable via cyberspace could be potential targets and potential threats. This includes networks and devices connected by wired connections, wireless connections and those that appear to be not connected at all. Adding to this ever-growing domain is the use of such technology in the expanding number of domestic goods, also known as the internet of things (IoT). […] Although today’s dependency on cyberspace brings associated risks, it provides military opportunities as well. An adversary may similarly rely on parts of cyberspace, such as computers, computerised networks, mobile devices and the electromagnetic environment and, therefore, may exhibit similar vulnerabilities.
