Which suite of applications is used to centrally manage and protect the DoDIN by deterring and denying adversary actions?

• A. Endpoint Security Solution (ESS)
• B. Domain Name System (DNS)
• C. Network Management Operator (NMO)
• D. Cyber Command and Control Mission System (C3MS)

Answer: (A)

The key idea is centralized endpoint protection across the DoDIN. An Endpoint Security Solution brings a single platform to manage every device—workstations, servers, laptops, and mobile devices—through unified policies, visibility, and automated responses. It deters and denies adversary actions by enforcing security configurations, preventing malware execution, blocking suspicious applications, and rapidly detecting and containing threats through features like antivirus, EDR (endpoint detection and response), application control, and patch management. With a central management console, security teams can push updates, monitor risk, and isolate or remediate affected devices quickly, creating a tougher barrier for attackers and reducing the chance of lateral movement across the network.

Other options don’t fit because DNS is about translating domain names to IPs and, while it can aid security, it isn’t a comprehensive, centrally managed protection suite for the DoDIN. The Network Management Operator concept isn’t a defined security solution for centralized protection. The Cyber Command and Control Mission System is focused on coordinating cyber operations, not providing the defensive endpoint protection and policy enforcement needed to deter and deny adversaries across the DoDIN.
