Which device serves as the secure boundary for Navy networks?

• A. WEB PROXY
• B. ADNS
• C. DNS
• D. FLEET FIREWALL

Answer: (D)

At the network edge, the boundary is protected by a device that can inspect and filter all traffic entering and leaving the Navy network, enforcing security policies and blocking threats. The Fleet Firewall is designed for this role, acting as the secure perimeter between trusted fleet networks and external networks, performing traffic inspection, rule enforcement, and often VPN termination. A web proxy focuses only on web traffic and caching, not the entire boundary; ADNS is a satellite communications system, not a security boundary device; and DNS translates domain names to IP addresses, which doesn’t gate or filter traffic. So the Fleet Firewall best serves as the secure boundary.
