Which of the following is a key principle of secure design?
AAllowing unlimited user access to all system parts
BIgnoring input validation to save time
CMinimizing access to only what is necessary
DUsing default passwords for convenience
Step-by-Step Solution
Solution:

  1. Step 1: Review secure design principles

    One main principle is to limit access to only what users need, called least privilege.

  2. Step 2: Evaluate each option

    Allowing unlimited access, ignoring input validation, and using default passwords increase risk, while minimizing access reduces vulnerabilities by restricting access.

  3. Final Answer:

    Minimizing access to only what is necessary -> Option C

  4. Quick Check:

    Least privilege = Minimize access [OK]
Quick Trick: Least privilege means only necessary access [OK]
Common Mistakes:
MISTAKES
  • Choosing options that increase risk for convenience
  • Ignoring the importance of input validation
  • Assuming default passwords are secure
