The answer is SQL injection attacks, as this is the primary risk of a WAF misconfiguration. A Web Application Firewall is specifically designed to inspect and filter HTTP traffic for malicious payloads, and when misconfigured—such as having flawed rule sets or disabled signature detection—it fails to block SQL injection attempts, allowing attackers to manipulate backend databases directly. On the CRISC exam, this question tests your understanding of control failures and their direct risk impact, often appearing as a distractor where candidates might incorrectly choose denial of service or network segmentation issues. A common trap is assuming a WAF handles all web threats equally, but its core function is application-layer input validation, not infrastructure or availability controls. Remember the memory tip: “WAF misconfig = SQL injection, not DoS or segmentation”—focus on the specific attack vector the control was built to prevent.
CRISC IT Risk Assessment Practice Question
This CRISC practice question tests your understanding of it risk assessment. 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.
Exhibit
Refer to the exhibit.
Exhibit: Architecture diagram description:
An e-commerce web application consists of a web server, application server, and database server in separate subnets. A WAF (Web Application Firewall) is placed in front of the web server. The web server communicates with the application server on port 8080, and the application server communicates with the database on port 3306.
What is the primary risk if the WAF is misconfigured?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.

A
SQL injection attacks
WAF misconfiguration increases vulnerability to web attacks.
B
Unauthorized database access
Why wrong: This may result from SQL injection but is a secondary effect.
C
Denial of service
Why wrong: DoS is possible but not the primary risk from WAF misconfiguration.
D
Network segmentation failure
Why wrong: Misconfigured WAF does not directly affect segmentation.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SQL injection attacks
A WAF protects against web application attacks such as SQL injection. If misconfigured, the web application is exposed. Option B is correct. Network segmentation failure (A) is not directly related. Denial of service (C) is a possibility but not the primary risk. Unauthorized database access (D) could result from SQL injection but is a consequence.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CRISC exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
