What is Data Loss Prevention (DLP) and its goal?

• A. A protocol for secure email transmission.
• B. A framework to deploy firewalls across the network.
• C. A method for compressing data to save space.
• D. A set of tools and policies to prevent data exfiltration and leakage.

Answer: (D)

Data Loss Prevention focuses on stopping sensitive information from leaving the organization. It uses data discovery, classification, and policy-based enforcement across endpoints, networks, and cloud services, employing content inspection and user context to detect potential leaks and prevent exfiltration by blocking actions, encrypting data, or alerting security teams. The aim is to keep confidential data in-house and compliant with laws and regulations as it moves through email, web, and cloud apps. This isn’t about secure email protocols, deploying firewalls, or simply compressing data for space savings.
