CYBER1: The Cyberspace Operations & Electronic Warfare SMARTbook

CYBER1: The Cyberspace Operations & Electronic Warfare SMARTbook (Multi-Domain Guide to Offensive/Defensive CEMA and CO) topics and chapters include cyber intro (global threat, contemporary operating environment, information as a joint function), joint cyberspace operations (CO), cyberspace operations (OCO/DCO/DODIN), electronic warfare (EW) operations, cyber & EW (CEMA) planning, spectrum management operations (SMO/JEMSO), DoD information network (DODIN) operations, acronyms/abbreviations, and a cross-referenced glossary of cyber terms.

United States armed forces operate in an increasingly network-based world. The proliferation of information technologies is changing the way humans interact with each other and their environment, including interactions during military operations. This broad and rapidly changing operational environment requires that today’s armed forces must operate in cyberspace and leverage an electromagnetic spectrum that is increasingly competitive, congested, and contested.


Cyberspace is a global domain within the information environment consisting of the interdependent network of information technology infrastructures and resident data, including the Internet, telecommunications networks, computer systems, and embedded processors and controllers. Operations in cyberspace contribute to gaining a significant operational advantage for achieving military objectives.


Cyber electromagnetic activities (CEMA) are activities leveraged to seize, retain, and exploit an advantage over adversaries and enemies in both cyberspace and the electromagnetic spectrum, while simultaneously denying and degrading adversary and enemy use of the same and protecting the mission command system (ADRP 3-0). CEMA consist of cyberspace operations, electronic warfare, and spectrum management operations.


Cyberspace operations (CO) are the employment of cyberspace capabilities where the primary purpose is to achieve objectives in or through cyberspace (JP 3-0). Cyberspace operations consist of three functions: offensive cyberspace operations, defensive cyberspace operations, and Department of Defense information network operations.


Electronic warfare (EW) is any military action involving the use of electromagnetic and directed energy to control the electromagnetic spectrum or to attack the enemy. EW consists of three functions: electronic attack, electronic protection, and electronic warfare support. These functions are referred to as divisions in joint doctrine.


Spectrum management operations (SMO) are the interrelated functions of spectrum management, frequency assignment, host-nation coordination, and policy that enable the planning, management, and execution of operations within the electromagnetic operational environment during all phases of military operations. SMO are the management portions of electromagnetic spectrum operations (EMSO). EMSO also include electronic warfare.


Department of Defense information network (DODIN) operations are operations to secure, configure, operate, extend, maintain, and sustain DOD cyberspace.


Cybersecurity ensures the confidentiality, integrity, availability, authentication, and nonrepudiation of friendly information and information systems while denying adversaries access to the same information and information systems. Cybersecurity incorporates actions taken to protect, monitor, analyze, detect, and respond to unauthorized activity on DOD information systems and computer networks.
