You have a Microsoft 365 E5 subscription that contains a user named User1.

You need to prevent users from sharing sensitive information with third-party generative AI websites.

A. Information Protection → Classifies and labels data but does not block sharing with external AI sites.

B. Information Barriers → Restricts communication between groups of users (e.g., compliance walls), not web uploads.

C. Insider Risk Management → Detects risky behavior (like data exfiltration), but does not actively block data sharing.

D. Data Loss Prevention (DLP) → Detects and prevents sensitive data being copied to browsers, USBs, or uploaded to restricted domains (like ChatGPT, Bard, etc.).
