156-315.81.20 Threat Prevention and SandBlast Practice Question
An administrator is troubleshooting why Threat Emulation is not inspecting files downloaded over HTTPS. The gateway is configured with HTTPS Inspection, but files are still bypassing emulation. What is the most likely cause?
⚠ Common exam trap
The trap here is assuming that enabling HTTPS Inspection globally is enough, when the policy must explicitly include the traffic to be inspected.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The HTTPS Inspection policy is not configured to inspect the relevant category or site.
For Threat Emulation to inspect files over HTTPS, HTTPS Inspection must be enabled and the policy must include the relevant traffic. If the policy does not cover the sites or categories, traffic bypasses inspection, and files are not emulated. Other options are either limitations that do not exist or are less likely given the scenario.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The gateway's HTTPS Inspection certificate is not trusted by the clients.
Why it's wrong here
If the certificate is not trusted, clients may see warnings or block connections, but the gateway might still inspect if configured to bypass on untrusted certificates. However, this would typically cause connectivity issues, not silent bypass of emulation. The most direct cause is policy configuration.
- ✗
Threat Emulation does not support files downloaded over HTTPS.
Why it's wrong here
Threat Emulation supports files from HTTPS traffic when HTTPS Inspection is enabled and configured to decrypt the traffic. It is not a limitation of emulation itself. The issue lies in the inspection configuration, not the emulation capability.
- ✗
Threat Emulation is only applied to HTTP traffic by default.
Why it's wrong here
Threat Emulation can inspect files from both HTTP and HTTPS traffic. By default, it may not inspect HTTPS unless HTTPS Inspection is enabled, but it is not limited to HTTP. The issue is that HTTPS Inspection is not properly configured to cover the traffic.
- ✓
The HTTPS Inspection policy is not configured to inspect the relevant category or site.
Why this is correct
HTTPS Inspection must be applied to the traffic. If the policy does not include the site or category, traffic will bypass inspection, and thus emulation. The most likely cause is that the HTTPS Inspection policy does not cover the sites being accessed, so files are not decrypted and sent to emulation.
