By focusing on developing strategic defenses, NATO aims to enhance its members' resilience to cyber-attacks, protect critical infrastructure, and ensure the collective security of its member states.

Strategic defenses involve not just technology, but also policies, training, and cooperation among member nations to effectively respond to cyber incidents. This approach reflects NATO's understanding that cyber-terrorism can have serious implications for national security and that a proactive and coordinated response is essential for deterrence and recovery.

The other options, while related to aspects of NATO's activities, do not capture the essence of its focus on cyber-terrorism as effectively as developing strategic defenses.

Military intervention does not typically apply to cyber-terrorism since the nature of the threat often requires different methods of response.
