The phrase 'Breadth of the perimeter' is used to convey that creating a 100% secure network is possible.

• A. True
• B. False
• C. Unsure
• D. None of the above

Answer: (B)

Expanding the network boundary does not guarantee perfect security. In practice, networks are diverse and fluid—they span on‑premises, cloud services, mobile devices, remote workers, and third‑party systems. Each edge or component introduces potential vulnerabilities, and attackers can exploit weak links like phishing, credential theft, misconfigurations, or zero‑day flaws. Even with broad, strong perimeter defenses, new threats emerge and internal threats exist, so absolute security is unattainable. Security is about reducing risk through defense in depth, continuous monitoring, and rapid incident response, not achieving a 100% secure network by simply widening the perimeter. Therefore, the statement is false.
