Which ownership space includes cyberspace owned and/or protected by the US, its mission partners, and the DoD?

The ownership space that encompasses cyberspace owned and/or protected by the United States, its mission partners, and the Department of Defense is referred to as blue. In this context, blue represents the friendly forces or environments that are actively defended.

Cyberspace is considered a complex domain that requires careful protection and coordination among various entities, including governmental and military sectors. The distinction of this ownership space emphasizes the importance of defending against threats and ensuring that these digital environments, which are crucial for national security and operational effectiveness, remain secure and operational.

In contrast, other options such as green, grey, and red may represent different operational environments or ownership spaces that do not align with the definition of cyberspace that is secured by the U.S. and its partners. By identifying and understanding the characteristics associated with the blue ownership space, relevant stakeholders can implement better strategies for cybersecurity and defense within their networks, thereby enhancing mission assurance.
