Cyber warfare differs from traditional warfare in several key ways:

Domain: Traditional warfare takes place in the physical domains of land, sea, and air, while cyber warfare takes place in the digital domain of computer networks and systems.
Weapons: Traditional warfare uses physical weapons such as guns, bombs, and tanks, while cyber warfare uses digital weapons such as malware, viruses, and hacking tools.
Targets: Traditional warfare targets military forces, infrastructure, and civilian populations, while cyber warfare can target a wider range of targets, including government agencies, businesses, and critical infrastructure.
Attribution: It can be difficult to attribute cyber attacks to specific actors, making it challenging to retaliate or hold perpetrators accountable.
Asymmetry: Cyber warfare allows smaller, less powerful actors to inflict significant damage on larger, more powerful adversaries.
Speed: Cyber attacks can occur much faster than traditional military operations, potentially causing damage in a matter of minutes or seconds.
Cost: Cyber warfare can be less expensive than traditional warfare, making it an attractive option for countries with limited resources.
Rules of Engagement: The rules of engagement in cyber warfare are still evolving, and there is no universally agreed-upon set of norms or laws governing cyber conflict.
Civilian Involvement: Cyber warfare can involve civilians as both targets and participants, blurring the lines between combatants and non-combatants.
Psychological Impact: Cyber warfare can have a significant psychological impact on individuals and societies, leading to fear, distrust, and social disruption.
