Which statement about border firewalls is supported by the material?

• A. Attackers are getting easier to bypass border firewalls.
• B. Attackers cannot bypass border firewalls.
• C. Border firewalls are always effective against bypass attempts.
• D. It depends on the organization.

Answer: (A)

Border defenses are not a guaranteed shield; attackers continually develop ways to slip through. The material emphasizes that as networks grow more complex and traffic becomes more encrypted or obfuscated, border firewalls can be bypassed more easily. For example, encrypted traffic like TLS/SSL often cannot be inspected by a firewall unless there’s deeper inspection in place, so malicious payloads can ride inside that allowed channel. Attackers can also use legitimate-looking traffic, VPNs, or tunnels on commonly open ports, and misconfigurations or overly permissive rules create blind spots. Because defenses rely on appropriate configuration, up-to-date signatures, and the ability to inspect content, any gaps can be exploited, making bypass attempts more feasible over time. This is why the material points out that attackers are getting easier to bypass border firewalls, rather than saying they cannot bypass, that they’re always effective, or that effectiveness depends on the organization in isolation.
