Which concept is designed to detect and prevent sensitive information from being stored or transmitted over unauthorized networks?

• A. Alert
• B. Block
• C. Data Loss Prevention (DLP)
• D. Reidentification

Answer: (C)

Data Loss Prevention focuses on protecting sensitive information from leaving the organization by detecting and controlling its transmission. It inspects data in use, in transit, and at rest, applying policies that recognize patterns like credit card numbers, Social Security numbers, or confidential documents. When a match occurs, DLP can block the transfer, quarantine the data, or require encryption, and it can also raise an alert for the security team. This directly addresses preventing sensitive information from being stored or transmitted over unauthorized networks, which is why it’s the best fit. The option that merely generates alerts isn’t enough on its own for prevention, and blocking is a possible action but not the concept itself; reidentification relates to identifying individuals in anonymized data and isn’t about preventing data leakage.
