What is the objective of the DoD’s Cybersecurity Strategy?

The primary objective of the Department of Defense's Cybersecurity Strategy is to protect and ensure the resilience of networks and systems. This encompasses safeguarding sensitive information from various cyber threats, ensuring the operational effectiveness of military capabilities, and maintaining the integrity and availability of critical systems. In the context of national defense, maintaining a robust cybersecurity posture is essential to prevent adversaries from exploiting vulnerabilities, conducting espionage, or launching attacks against the DoD infrastructure. The emphasis on resilience means not only defending against attacks but also having the capability to recover and sustain operations even when faced with some level of cyber incident.

The other options do not accurately reflect the overarching goals of the strategy. Ensuring open access to all information systems contradicts the need for secure handling of sensitive and classified information. Promoting public awareness of cyber threats is important but is more of an outreach effort rather than a core objective of the DoD's strategy. While limiting internet access might enhance security in certain contexts, it does not align with the broader goal of protecting and maintaining operational networks and systems.
