  3. C
    User authentication verification
  4. D
    Detective audit logging

Cevap

Data masking
Data masking is a privacy control that replaces or redacts sensitive data elements when rendered on screen, while preserving the full, original dataset in secure storage for processing.

Adım Adım Çözüm

1
Identify the primary operational requirement.
The requirement is to visually conceal sensitive account numbers on screen while leaving the underlying database records intact.
Customer support representatives only need to verify card identity without seeing full sensitive numbers.
2
Evaluate data protection controls.
Data masking redacts or replaces characters (e.g., showing ** ** 1234) for display purposes without altering stored data.
This technique provides effective privacy protection against shoulder surfing or unnecessary data exposure during support interactions.
