Which term is used to describe the collection of devices that support network defense?

• A. Joint Regional Security Stack
• B. Regional Security Framework
• C. Cyber Defense Grid
• D. Security Operations Network

Answer: (A)

The term used for the collection of devices that support network defense is Joint Regional Security Stack. This describes a regional assembly of security devices—like firewalls, intrusion prevention systems, proxies, and related appliances—that work together to monitor, filter, and defend DoD networks across a region. The JRSS provides centralized policy enforcement and visibility, ensuring consistent defense across multiple bases and networks within that region. Other options don’t match this formal construct. A regional security framework suggests a governance or policy approach rather than the tangible stack of devices. A cyber defense grid is a more generic phrase that isn’t the established name for this DoD architecture. A security operations network refers to the operations network used by defenders, not the standardized collection of devices deployed for regional network defense.
