- A
Restrict database user permissions to only necessary tables
Why wrong: Least privilege limits damage but does not prevent injection.
- B
Implement strict input validation for all user inputs
Why wrong: Input validation can reduce risk but can be bypassed; parameterization is the definitive fix.
- C
Deploy a web application firewall (WAF) in front of the application
Why wrong: WAF is a compensating control, not a code fix.
- D
Rewrite all dynamic queries to use parameterized queries
Parameterized queries prevent interpretation of user input as SQL code.

SQL Injection Remediation: Rewrite Dynamic Queries to Use Parameterized Queries
This SSCP practice question tests your understanding of sscp exam topics. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 database administrator notices unusual queries that seem to be trying to extract data via SQL injection. The application uses parameterized queries for most queries, but some dynamic queries are built using string concatenation. What is the BEST remediation?
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
✓
Rewrite all dynamic queries to use parameterized queries
Option D is correct because rewriting all dynamic queries to use parameterized queries separates SQL code from user data, effectively preventing SQL injection. Option A (restricting permissions) reduces damage but does not stop injection. Option B (input validation) is helpful but can be bypassed if concatenation remains. Option C (WAF) is a detection/blocking measure, not a code-level fix.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Restrict database user permissions to only necessary tables
Why it's wrong here

Why it's wrong here
WAF is a compensating control, not a code fix.
- ✓
Rewrite all dynamic queries to use parameterized queries
Why this is correct
Parameterized queries prevent interpretation of user input as SQL code.

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 security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.

Same concept, more angles
1 more ways this is tested on SSCP
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 security administrator discovers that a web application is vulnerable to SQL injection. Which of the following is the most effective mitigation to implement at the application layer?
medium- A.Implement input validation using a blacklist of SQL keywords.
- B.Encrypt the database connection using TLS.
- ✓ C.Use parameterized queries or prepared statements.
- D.Encode all output sent to the browser.
- E.Deploy a web application firewall (WAF) in front of the server.
Why C: Option C (parameterized queries or prepared statements) is the most effective mitigation at the application layer because it ensures user input is treated as data, not executable SQL code, thus preventing SQL injection. Option A (input validation via blacklist) can be bypassed by attackers using encoding or alternative characters. Option B (encrypting the database connection with TLS) protects data in transit but does not prevent SQL injection. Option D (output encoding) addresses cross-site scripting (XSS), not SQL injection. Option E (deploying a WAF) operates at the network layer and can be circumvented; it is not an application-layer control.
