What is the collection of network security devices called?

• A. Joint Regional Security Stack (JRSS)
• B. Regional Security Network
• C. Cyber Defense Grid
• D. Network Security Suite

Answer: (A)

Joint Regional Security Stack is the collection of network security devices. In DoD networks, JRSS bundles boundary security components—firewalls, intrusion prevention systems, proxies, VPN gateways, and similar devices—into a single regional stack. This centralizes policy enforcement, monitoring, and threat protection across multiple connected networks within a region, providing consistent security controls and simpler management. The other terms listed refer to more generic or different concepts and aren’t the official name for this DoD architecture, so JRSS best fits the described collection.
