Correct answer & explanation
✓
Validate and sanitize all user inputs
Rate limiting, input validation, and least privilege are key API security practices. Mass assignment is a vulnerability to avoid, not a practice, and exposing all endpoints is contrary to security.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Validate and sanitize all user inputs
Why this is correct
Input validation prevents injection attacks.
- ✗
Expose all API endpoints automatically for transparency
Why it's wrong here
Exposing all endpoints increases attack surface; only needed endpoints should be exposed.
- ✗
Allow mass assignment for ease of development
Why it's wrong here
Mass assignment can lead to data tampering; it should be explicitly defined.
- ✓
Implement rate limiting to prevent abuse
Why this is correct
Rate limiting mitigates brute force and DoS attacks.
- ✓
Apply least privilege to API keys and roles
Why this is correct
Least privilege limits the impact of compromised credentials.
