A company wants to design a secure system that protects user data and prevents unauthorized access. Which combination of design choices best achieves this?
AUse strong authentication, encrypt data, and apply least privilege access.
BAllow all users full access and skip encryption to improve speed.
CUse default passwords and store data in plain text for easy access.
DIgnore input validation but monitor logs for suspicious activity.
Step-by-Step Solution
Solution:

  1. Step 1: Identify key secure design elements

    Strong authentication verifies users, encryption protects data, and least privilege limits access.

  2. Step 2: Evaluate each option's security impact

    Use strong authentication, encrypt data, and apply least privilege access combines all good practices; others increase risk by ignoring encryption, access control, or validation.

  3. Final Answer:

    Use strong authentication, encrypt data, and apply least privilege access. -> Option A

  4. Quick Check:

    Strong auth + encryption + least privilege = Secure design [OK]
Quick Trick: Combine strong auth, encryption, and least privilege [OK]
Common Mistakes:
MISTAKES
  • Choosing convenience over security
