What is Computer Network Operations (CNO) and what are its main areas of operation?

• A. Space-based orbital surveillance.
• B. Cyber operations focusing on independent data storage.
• C. Computer Network Operations; defensive protection of DoD networks and offensive actions to disrupt or degrade adversary networks when authorized.
• D. Public relations campaigns for network security.

Answer: (C)

The main idea being tested is what Computer Network Operations encompasses and how it is applied. CNO covers both defensive and offensive cyber activities within the DoD. On the defensive side, it means protecting DoD networks and information systems—detecting threats, preventing intrusions, and responding to incidents to keep critical operations secure. On the offensive side, it involves authorized actions intended to disrupt, degrade, or defeat adversary networks and capabilities in cyberspace, carried out under approved authorities and rules of engagement. This combination—defense of our own networks plus authorized, targeted operations against adversaries—defines CNO. Other options miss the mark because space-based surveillance relates to space operations, data storage isn’t about active network operations, and public relations campaigns don’t involve cyber operations.
