Which strategy can help prevent protected health information from being shared outside a company using Microsoft 365?

Data Loss Prevention (DLP) policies are specifically designed to prevent sensitive information, such as protected health information (PHI), from being inadvertently shared outside an organization. DLP policies in Microsoft 365 can identify, monitor, and protect sensitive items by applying rules that trigger protective actions when sensitive information is detected in emails, documents, or other communications.

These policies can automatically block the sharing of sensitive information, notify users of policy violations, or encrypt data to manage how it is shared. By applying DLP policies, organizations can establish clear guidelines on how to handle sensitive data, preventing unintended exposure outside the company.

While insider risk management policies and end-user training programs are valuable for addressing potential threats and educating employees, respectively, they do not directly implement technical controls to prevent data sharing. Azure Rights Management also plays a role in protecting information through encryption and rights assignments, but DLP policies provide a more complete framework for managing and preventing the unintentional dissemination of sensitive health information.
