The first thing to check when a FortiGate WAF is not blocking SQL injection attacks is whether the SQL injection signatures are actually enabled in the WAF profile. This is the most common oversight because even with a WAF profile applied, the specific signature set for SQL injection must be toggled on; if it is disabled, the FortiGate simply will not inspect traffic for those patterns, allowing attacks to pass through undetected. On the Fortinet NSE 7 Advanced Security NSE7 exam, this scenario tests your understanding of WAF profile configuration granularity—specifically that signature groups are not active by default and must be explicitly enabled. A common trap is assuming that applying any WAF profile automatically blocks all OWASP Top Ten threats, but the exam emphasizes that each signature category (SQLi, XSS, etc.) requires manual activation. Remember the memory tip: “Signatures sleep until you wake them”—always verify the SQL injection toggle is set to “Enable” in the WAF profile’s signature settings.
NSE7 Advanced Threat Protection Practice Question
This NSE7 practice question tests your understanding of advanced threat protection. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator configures a WAF profile on FortiGate to protect a web application. However, the administrator notices that SQL injection attacks are not being blocked. What should the administrator check first?

Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The SQL injection signatures are enabled in the WAF profile
WAF signatures must be enabled in the WAF profile. If SQL injection signatures are disabled, they will not be detected.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 SQL injection signatures are enabled in the WAF profile
Why this is correct
WAF profiles have signature sets; SQL injection must be enabled.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
The WAF profile is attached to the correct firewall policy
Why it's wrong here
This is important but if signatures are disabled, attacks won't be blocked.
✗
The FortiGate has a valid Advanced Web Protection subscription
Why it's wrong here
WAF is included in UTM or Advanced, but signature enablement is the first check.
✗
The web application is using HTTPS and SSL inspection is configured
Why it's wrong here
SSL inspection is needed for HTTPS, but the issue is SQL injection not being blocked.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related NSE7 NAT questions on configuration and troubleshooting.
Advanced Threat Protection — This question tests Advanced Threat Protection — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: The SQL injection signatures are enabled in the WAF profile — WAF signatures must be enabled in the WAF profile. If SQL injection signatures are disabled, they will not be detected.
What should I do if I get this NSE7 question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related NSE7 NAT questions on configuration and troubleshooting.
Are there clue words in this question I should notice?
Yes — watch for: "first". Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
