Which type of warfare involves attacking the ICT assets of an opponent?

Offensive Information Warfare refers to the tactics and strategies employed to intentionally attack or disrupt an adversary's information and communication technology (ICT) assets. This type of warfare is characterized by the proactive approach of launching cyberattacks to gain a strategic advantage, disrupt operations, gather intelligence, or cause damage to an opponent's critical information systems. Offensive actions can include hacking into networks, deploying malware, or conducting denial-of-service attacks.

In contrast to the other options, which focus on protecting or defending ICT systems, Offensive Information Warfare specifically emphasizes aggression against these assets. For instance, Defensive Information Warfare centers around safeguarding information systems from attacks, Information Security Actions focus on implementing security measures to protect data and information, and Cyber Defensive Operations involve countermeasures to defend against ongoing cyber threats.
