What is a primary responsibility of the NCDOC?

The primary responsibility of the NCDOC, or Navy Cyber Defense Operations Command, is to protect the Navy's computer networks. This involves monitoring, defending, and safeguarding the Navy's cyber infrastructure from various threats, including cyberattacks and unauthorized access. By prioritizing the integrity, availability, and confidentiality of sensitive information, NCDOC ensures that naval operations can proceed without disruption due to cyber-related issues.

The other options involve important functions, but they do not align with the core mission of the NCDOC. Logistical support, surveillance, and coordination of naval drills pertain to different branches of naval operations and command structures, which focus on physical and tactical aspects rather than the cybersecurity domain that NCDOC specializes in.
