Cyber defense (also spelled cyberdefense and cyber defence) (CyD) refers to

actions combine information assurance, computer network defense (to include response actions), and critical infrastructure protection with enabling capabilities (such as EP, critical infrastructure support, and others) to prevent, detect, and ultimately respond to an adversaries ability to deny or manipulate information and/or infrastructure. CyD is integrated with the dynamic defensive aspects of CyberWar to provide defense in depth.[1]

United States[]

The U.S. government has issued a statement concerning its response to cyberattacks:

[w]hen warranted, we [the United States] will respond to hostile acts in cyberspace as we would to any other threat to our country. All states possess an inherent right to self-defense, and we reserve the right to use all necessary means — diplomatic, informational, military and economic — to defend our Nation, our Allies, our partners, and our interests.[2]
