The need for cyber and electromagnetic activities Chapter 1 – The need for cyber and electromagnetic activities Section 1 – Introduction 1.1. Cyber and electromagnetic activities (CEMA) are interdependent and within the electromagnetic environment (EME). The EME will be contested by actors using both cyber and electromagnetic activity to achieve operational advantage. Digitisation has led to the convergence of cyber and information activities to such an extent that CEMA coordination across the joint force will be imperative for operational success. Freedom to flexibly use or to deny, degrade or constrain adversary access to the EME and parts of cyberspace will offer significant operational advantage. 1 The CEMA Vision is: ‘The synchronisation and coordination of cyber and electromagnetic activities, delivering operational advantage thereby enabling freedom of movement, and effects, whilst simultaneously, denying and degrading adversaries’ use of the electromagnetic environment and cyberspace.’1 1.2. CEMA must address the longstanding challenges of acquiring, using and integrating information with physical actions to create the desired effect. In addition, information and the systems which create, collect, manage and exploit this information, are critical to successful conflict outcomes. The need for CEMA coordination, coherent with a full spectrum approach and mission assurance, has escalated in recent years because of the sheer volume of information, the ease of access to it and the increasing means by which it can be exploited.1 1 The Cyber and Electromagnetic Activities (CEMA) Vision was devised by the CEMA Capability Integration Group (CIG).
