What is the purpose of Data Loss Prevention (DLP) in a network?

• A. Detects and prevents sensitive information from being stored or transmitted over unauthorized networks
• B. Shields data by encrypting all transmissions
• C. Logs all user activities for auditing
• D. Blocks all outbound data automatically

Answer: (A)

Data loss prevention is about stopping sensitive information from leaving the organization or being stored in places that aren’t allowed. It looks at the content and context of data—what it contains, where it’s going, and who is handling it—and enforces policies to block, quarantine, or alert when that data could be exposed over the network, in email, on endpoints, or in cloud storage. Encryption protects data in transit or at rest but doesn’t itself decide what can be transmitted or stored, logging records activity without stopping leakage, and blocking every outbound transfer would disrupt legitimate work. So, the best description is that DLP detects and prevents sensitive information from being stored or transmitted over unauthorized networks.
