CCSP Cloud Application Security Practice Question
Which TWO of the following are secure coding practices that help prevent injection attacks?
⚠ Common exam trap
ISC2 often tests the misconception that stored procedures are inherently safe against injection, but the trap is that stored procedures can still be vulnerable if they dynamically construct SQL strings using concatenated input, so parameterization must be applied inside the procedure as well.
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
✓
Using parameterized queries for database calls
Parameterized queries (also known as prepared statements) separate SQL logic from data by using placeholders (e.g., `?` in MySQLi or `:param` in PDO). The database driver treats the user-supplied values strictly as data, never as executable code, which prevents an attacker from injecting malicious SQL commands even if the input contains special characters like `' OR 1=1 --`.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Printing stack traces in production error messages
Why it's wrong here
This exposes system details to attackers.
- ✓
Using parameterized queries for database calls
Why this is correct
Parameterized queries separate SQL logic from data, preventing injection.
- ✗
Using stored procedures exclusively
Why it's wrong here
Stored procedures can still be vulnerable if they use dynamic SQL.
- ✓
Validating and sanitizing all user inputs
Why this is correct
Input validation filters out malicious content before processing.
- ✗
Storing user passwords in plaintext
Why it's wrong here
Passwords should be hashed and salted, not stored in plaintext.
