Cyber warfare is defined as a modern form of conflict in which states or organizations attempt to gain advantage over one another through digital attacks targeting computer systems, critical infrastructure, military networks, and government institutions. Unlike traditional warfare, cyber warfare does not rely on physical force; instead, its objective is to disrupt information flow, disable systems, or obtain strategic superiority. Today, cyber warfare has become an integral part of national security, evolving into an invisible yet highly impactful power struggle between nations.

Technically, cyber warfare encompasses a wide range of tactics, including malware deployment, DDoS attacks, data theft, critical infrastructure sabotage, social engineering, and advanced persistent threat (APT) operations. Countries build dedicated cyber armies, threat-intelligence hubs, and advanced defensive systems to carry out or counteract such operations. Speed, stealth, intelligence, and technological superiority play decisive roles in cyber warfare. For these reasons, cyberspace is now recognized as the fifth domain of warfare, holding strategic importance comparable to traditional combat environments.
