How can you use Microsoft Information Protection (MIP) labels to automatically classify and protect sensitive documents uploaded to OneDrive?

To automatically classify and protect sensitive documents uploaded to OneDrive using Microsoft Information Protection (MIP) labels, you need to configure auto-labeling policies and sensitivity labels within the Microsoft Purview compliance portal. First, create and publish sensitivity labels that define the classification and protection settings for different types of sensitive data. These labels can apply encryption, content markings (headers, footers, watermarks), and access restrictions. For example, you might create a 'Confidential' label that encrypts documents and restricts access to specific users or groups. Next, create auto-labeling policies that automatically apply these sensitivity labels based on content inspection. Within the Microsoft Purview compliance portal, navigate to Information Protection > Auto-labeling. Define rules within these policies that identify sensitive information based on keywords, sensitive information types (e.g., credit card numbers, social security numbers), or trainable classifiers. For example, create a rule that automatically applies the 'Confidential' label to any document containing credit card numbers that is uploaded to OneDrive. Finally, configure the auto-labeling policy to apply the sensitivity label automatically. When a user uploads a document to OneDrive that matches the conditions defined in the auto-labeling policy, the corresponding sensitivity label will be automatically applied to the document. This ensures that the document is classified and protected according to the settings defined in the label. The document is encrypted, marked, and access is restricted as configured in the sensitivity label. This approach ensures that sensitive data stored in OneDrive is automatically protected, reducing the risk of data leakage and helping to meet compliance requirements.
