Border management ________.

• A. is no longer important because there are so many ways to bypass borders
• B. is close to a complete solution to access control
• C. Both A and B
• D. Neither A nor B

Answer: (D)

Border management is part of a layered approach to security, helping to control traffic at the network edge and enforce policies as traffic enters or leaves the environment. It remains important because it reduces the attack surface, gives visibility into what’s crossing the boundary, and stops or slows many unwanted actions before they reach internal systems. But it’s not a standalone solution that can guarantee complete access control.

Why the options that claim it’s no longer important are not correct: even with sophisticated evasion techniques, border controls still provide essential containment and monitoring. They establish the first line of defense and help detect anomalies at the perimeter, which is valuable in any security program.

Why the option that says it’s close to a complete solution is not correct: no single control, especially at the border, can fully guarantee who should access what across diverse environments like on-premises, cloud, and remote workers. Encrypted traffic, insider threats, and the need for identity-based and device-based verifications mean access decisions must be made beyond the border. A defense-in-depth approach, incorporating identity and device posture, internal network segmentation, continuous monitoring, and possibly zero-trust principles, is required.

So, neither statement is accurate, and border management should be considered a vital, ongoing part of a broader, layered security strategy.
