NSE7 Advanced Threat Protection Practice Question
An organization uses FortiGate's WAF feature (not FortiWeb) to protect a web server. The admin configures an inline WAF profile but notices that the WAF is not inspecting traffic. What is the most likely cause?
⚠ Common exam trap
Many candidates assume applying a WAF profile to a policy is enough, overlooking that FortiGate requires explicit SSL Inspection decryption to inspect HTTPS traffic, which is the most common oversight in WAF deployments.
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
✓
SSL Inspection is not enabled on the firewall policy
FortiGate's WAF feature operates at the application layer and requires SSL Inspection to decrypt HTTPS traffic before the WAF engine can analyze the payload. Without SSL Inspection enabled on the firewall policy, the WAF profile sees only encrypted traffic and cannot inspect HTTP/HTTPS content, effectively rendering the WAF non-functional for encrypted sessions.
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 WAF profile is not applied to a firewall policy
Why it's wrong here
The admin says the profile is applied.
- ✓
SSL Inspection is not enabled on the firewall policy
Why this is correct
Without decryption, FortiGate cannot inspect encrypted traffic for WAF rules.
- ✗
The firewall policy uses flow-based inspection
Why it's wrong here
WAF on FortiGate works in both flow and proxy modes, but SSL inspection is still required.
- ✗
The WAF profile is configured in monitor mode
Why it's wrong here
Monitor mode would still inspect and log, not fail to inspect.
