The correct answer is option D: F-SBID( --name "HTTP_EXPLOIT" --protocol http --header Host --content "EXPLOIT" ). This syntax is correct because the FortiGate custom IPS signature engine requires the `--protocol http` flag to explicitly target the application-layer HTTP traffic, and the `--header Host` parameter to narrow the inspection to the HTTP Host header field specifically. The `--content` directive then defines the exact string 'EXPLOIT' to match within that header, enabling precise detection of the exploit without false positives from other header fields. On the Fortinet NSE 7 Advanced Security NSE7 exam, this question tests your ability to construct a valid F-SBID rule, a common task when creating custom IPS signatures for targeted threats. A frequent trap is omitting `--protocol http` or using `--header` without specifying the exact field name, which would cause the signature to fail or match incorrectly. Remember the memory tip: "Protocol first, then header, then content" — always specify the protocol before the header field to ensure the signature engine knows which layer to inspect.
NSE7 Advanced Threat Protection Practice Question
This NSE7 practice question tests your understanding of advanced threat protection. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 admin wants to create a custom IPS signature to detect a specific exploit that sends a string 'EXPLOIT' in the HTTP Host header. Which signature syntax is correct?
Option D is correct because the FortiGate custom IPS signature syntax requires the `--protocol http` flag to specify the application-layer protocol for HTTP inspection, and `--header Host` to target the HTTP Host header field. The `--content` parameter then defines the string 'EXPLOIT' to match within that header, enabling precise detection of the exploit.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse `--protocol tcp` with `--protocol http`, not realizing that HTTP header inspection requires the application-layer protocol keyword to enable the HTTP parser, even though HTTP traffic uses TCP as its transport.
Detailed technical explanation
How to think about this question
FortiGate IPS signatures use the F-SBID syntax, where `--protocol http` triggers the HTTP parser to decode the request and expose header fields like Host, User-Agent, and URI for pattern matching. The `--header` directive then specifies the exact header name to inspect, and `--content` performs a case-sensitive string match within that header's value. This approach is more efficient than raw TCP payload matching because it avoids false positives from binary data and allows the IPS engine to leverage protocol awareness for accurate detection.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway

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 is the correct answer to this question?
The correct answer is: F-SBID( --name "HTTP_EXPLOIT" --protocol http --header Host --content "EXPLOIT" ) — Option D is correct because the FortiGate custom IPS signature syntax requires the `--protocol http` flag to specify the application-layer protocol for HTTP inspection, and `--header Host` to target the HTTP Host header field. The `--content` parameter then defines the string 'EXPLOIT' to match within that header, enabling precise detection of the exploit.
