CIBERDEFENSA ORIENTACIONES PARA EL DISEÑO, PLANEAMIENTO, IMPLANTACIÓN Y DESARROLLO DE UNA CIBERDEFENSA MILITAR 6 Cyberspace is no longer an emerging domain, but a potential theatre of war in which all sovereign nations could be actively engaged on a daily basis. Around the world, state and non-state actors have developed cyber capabilities, both offensive and defensive, that have triggered are- examination of traditional notions of global power, influence and even warfare. Today, there is a global dependence on readily available computers and networks for most aspects of governmental, financial, commercial, industrial, and to command and control military operations - a dependence that has introduced both great opportunity and significant risk. Cyber threats to the security of the Western Hemisphere are becoming more frequent, complex, destructive and coercive. We must adapt to the evolving cyber threat landscape. The Americas require strong and resilient cyber defenses to fulfil critical tasks such as collective defense, crisis management and cooperative security. We need to be prepared to defend our networks and operations against the growing sophistication of the cyber threats and attacks we all face. Cyber-defense is critical to the conduct of modern military operations. Military cyber infrastructure presents potential single points of failure for operations, training, and activities. Freedom of action within and through cyberspace depends on our ability to protect and defend against accidental, malicious or adversarial action. Cybersecurity is the foundation of preserving freedom of action in cyberspace. It comprises the application of security measures for the protection of communication, information and other electronic systems, as well as the information that is stored, processed or transmitted in these systems in order to safeguard confidentiality, integrity, and availability. Good cybersecurity sets the conditions for effective operational command and control of military forces. Since cyberspace is not constrained to a single country, protecting our interests in cyberspace is a team sport. Developing a strong, combined defense against malicious cyber activity requires collective will to coordinate, collaborate and share best practices in the development of cyber forces, and the execution of cyber operations. This guide is a first step in advancing the development of national cyber forces capable of operating in this new environment, singly and collectively, in defense of our common goals. I encourage all participating nations to review and consider its recommendations closely and look forward to cooperating in cyberspace to secure a safe and prosperous future.
