The need for cyber and electromagnetic activities a. Assure CEMA capability coherence across Defence and the Government Communications Headquarters (GCHQ) for both new and existing capabilities. b. Inform and shape CEMA capability across Defence lines of development ensuring coherence across Service Commands, Defence Equipment and Support, Information Systems and Services and Defence Science and Technology Laboratory. c. Influence the production of CEMA policy and doctrine. d. Ensure key CEMA component and Service Command personnel receive core training at tactical, operational and strategic levels. 1 e. Enable electromagnetic activities (EMA) and cyber activities to be developed coherently under the CEMA strategy.4 f. Establish relationships with Defence industrial partners for supply chain issues and vulnerabilities. 1.6. As cyber and EMA functions mature, CEMA will change. However, consideration must be given to how cyber and EMA capabilities under development can be synchronised and coordinated into the full spectrum approach. A CEMA policy, planned for 2018, will develop the links between cyber and EMA. 4 The Joint Force Cyber Group and British Army, as well as the United States of America Cyber Command, work to the National Institute of Standards and Technology Cyber Security Framework which provides a useful common language and description of functions (identify, protect, detect, respond, recover and their sub-categories). The CEMA strategy covers the period from 2017 to 2025 through three phases: phase 1 – definition and refinement (2017-2020); phase 2 – implementation (2020-2025); and phase 3 – business as usual (2025 onwards).
