Which term refers to the use of military force to engage in warfare through cyberspace?

The term that specifically refers to the use of military force to engage in warfare through cyberspace is cyber warfare. This concept encompasses a range of offensive and defensive operations undertaken in the digital domain, including the disruption of an enemy's information systems, espionage, and attacks on critical infrastructure.

Cyber warfare is distinct in that it utilizes the internet and other digital networks to conduct military operations and can involve a variety of tactics such as hacking, deploying malware, and manipulating data to achieve strategic objectives. The increasing reliance on information technology in modern military operations has made cyber warfare a critical aspect of national security strategy, allowing states and non-state actors alike to exert influence and power in a covert and often deniable manner.

The other terms listed do not adequately capture the full scope and intent of military operations conducted in cyberspace. For instance, information warfare generally refers to the broader concept of manipulating information and public perception, rather than specifically military engagement through digital means. Network conflict and digital combat are less commonly used terms and do not have a defined military doctrine associated with them like cyber warfare does.
