Quick Answer
The answer is Web Application Firewall (WAF) Signatures. FortiWeb uses these pre-configured signatures to inspect HTTP requests for malicious SQL patterns, comparing incoming data against a regularly updated database of known injection strings. This allows the appliance to block SQL injection attacks at the application layer before they reach the backend database. On the Fortinet NSE 7 Advanced Security NSE7 exam, this concept tests your understanding of signature-based detection versus anomaly-based or machine learning methods—a common trap is confusing WAF signatures with IPS signatures, which operate at the network layer. Remember that for web-specific threats like SQL injection, you must enable the dedicated WAF signature set under the Web Protection profile. A useful memory tip: think of WAF signatures as a "bouncer checking IDs at the door" for every HTTP request, while IPS signatures are more like a "patrol officer watching the street."
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.
A company uses FortiWeb to protect its web application. They want to block SQL injection attempts. Which FortiWeb feature should be configured to inspect HTTP requests for malicious SQL patterns?
URL Access Rule
Why wrong: URL Access Rules control access based on URL patterns, not content inspection.
Web Application Firewall (WAF) Signatures
WAF Signatures include pre-defined rules for SQL injection, XSS, etc.
HTTP Protocol Constraint
Why wrong: Protocol constraints check HTTP compliance, not specific attack patterns.
IP List
Why wrong: IP List blocks by IP address, not payload patterns.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Web Application Firewall (WAF) Signatures
FortiWeb uses Web Application Firewall signatures to detect SQL injection. These are pre-configured signatures that match SQL patterns.
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
For each option: why learners choose it and why it is or isn't the right answer here.
URL Access Rule
Why it's wrong here
URL Access Rules control access based on URL patterns, not content inspection.
Web Application Firewall (WAF) Signatures
Why this is correct
WAF Signatures include pre-defined rules for SQL injection, XSS, etc.
Related concept
Static NAT maps one inside address to one outside address.
HTTP Protocol Constraint
Why it's wrong here
Protocol constraints check HTTP compliance, not specific attack patterns.
IP List
Why it's wrong here
IP List blocks by IP address, not payload patterns.
Common exam traps
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
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.
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
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
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company uses FortiGate as a web application firewall (WAF) to protect a public web server. The security team wants to block SQL injection attacks. Which WAF signature category should the administrator enable?
mediumWhy C: The correct answer is C because SQL injection attacks specifically target database queries by injecting malicious SQL statements through input fields. FortiGate's WAF signature category for SQL Injection is designed to detect and block these patterns, such as 'OR 1=1' or UNION-based injections, by matching against known attack signatures in the HTTP request payload.
Variation 2. A company uses FortiWeb as a reverse proxy for their web application. They want to protect against SQL injection attacks. Which FortiWeb feature should be configured?
mediumWhy A: FortiWeb's Web Protection Profile includes a dedicated 'SQL Injection Prevention' module that uses signature-based and behavioral analysis to detect and block SQL injection attempts at the application layer. This is the correct feature because FortiWeb is a web application firewall (WAF) designed specifically for HTTP/HTTPS traffic, and SQL injection protection is a core WAF function, not a general IPS or network-layer feature.
