Which of the following is NOT a goal of Computer Network Attack?

Gathering intelligence is not typically classified as a goal of Computer Network Attack (CNA). CNA primarily focuses on offensive operations that aim to disrupt, deny, degrade, or destroy the information and operational capabilities of adversaries' networks.

Disrupting communication networks serves the purpose of impeding the adversary's ability to coordinate or communicate effectively during an operation, directly aligning with the strategic goals of a CNA. Destroying data in networks can significantly impact an adversary's operational readiness and effectiveness, coinciding with the disruptive nature of such attacks. Denial of service to adversaries intentionally prevents them from accessing essential services or information, which is another tactic employed under the umbrella of CNA to weaken an opponent's capabilities.

In contrast, while intelligence gathering is a critical component of military operations and strategic planning, it does not fall under the umbrella of attack methodologies like those mentioned above. Instead, it is more aligned with surveillance, reconnaissance, and information collection efforts designed to inform decision-making rather than directly engaging in disruptive or destructive actions against networks.
