What is "cyber warfare" in the context of military operations?

Cyber warfare refers to the strategic use of digital attacks against an adversary to disrupt, damage, or gain access to their computer systems and networks. It encompasses a variety of offensive and defensive actions that aim to exploit vulnerabilities in information systems, particularly in a military context. These operations can target critical infrastructure, command and control systems, and information networks to degrade an opponent's military capabilities and overall effectiveness.

In this context, option B accurately captures the essence of cyber warfare by emphasizing the active conduct of operations designed to impact the enemy's digital assets. Such operations may include hacking, deploying malware, or executing denial-of-service attacks, all with the intent of hindering the enemy's operations or gathering intelligence.

The other choices do not align with the definition of cyber warfare. Engaging in negotiation via online platforms relates to diplomatic interactions rather than military actions. Training personnel in cybersecurity is a preventative measure and a form of defense, not an offensive strategy. Using drones for aerial surveillance pertains to traditional military tactics and operations, while cyber warfare specifically focuses on the digital realm rather than physical operations.
