Tutorial / Cram Notes
Microsoft 365 provides a comprehensive suite of tools and features to help manage and protect sensitive information. Two key aspects are Data Loss Prevention (DLP) and classification labels. These features enable organizations to detect, monitor, and protect sensitive information across various locations such as Exchange Online, SharePoint Online, OneDrive for Business, and Microsoft Teams.
Data Loss Prevention (DLP)
DLP in Microsoft 365 helps to identify, monitor, and automatically protect sensitive information. With DLP policies, you can control the flow of sensitive information and prevent accidental sharing of data that is subject to regulatory compliance or carries business confidentiality.
How DLP works:
- Detection: DLP policies are configured with rules that define what is considered sensitive information. These can be based on regulatory standards like HIPAA, GDPR, or custom patterns like credit card numbers or identification numbers.
- Notification: When sensitive information is shared in a way that violates a DLP policy, the system can notify the user and administrators.
- Protection: DLP can block access to the content, prevent its sharing, or create incident reports for compliance officers.
Examples of DLP actions include:
- Encrypting email messages containing sensitive information.
- Preventing the sharing of sensitive files externally.
- Blocking users from sending sensitive data to unauthorized recipients.
Classification Labels
Classification labels in Microsoft 365 serve as a method for categorizing and protecting documents and emails. These labels can be applied manually by users or automatically based on certain criteria.
How classification labels work:
- Manual Classification: Users can apply labels to documents and emails according to the content sensitivity. For example, marking a document as “Confidential”.
- Automatic Classification: Administrators can configure policies to automatically classify and label content based on its characteristics. For instance, any document containing a social security number could be automatically labeled as “PII” (Personally Identifiable Information).
Benefits of using classification labels:
- Protection: Labels can enforce protection settings such as encryption and access restrictions.
- Retention: They can define retention periods, ensuring data is kept only as long as necessary.
- Compliance: Helps maintain regulatory compliance by ensuring sensitive data is handled correctly.
When both DLP and classification labels are combined, organizations have a robust set of tools to protect sensitive data both in-transit and at-rest. Here’s a comparison of what DLP and classification labels can achieve.
| Feature | Data Loss Prevention (DLP) | Classification Labels |
| Primary Objective | Preventing accidental data breaches | Organizing and securing information |
| Detection | Based on content in motion | Can apply to content at rest or in motion |
| Application | Actions such as block, notify, restrict access | Metadata that influences actions |
| User Interaction | Policy tips can educate users on compliance | Users may apply or see labels |
| Automation | Can automatically protect based on policy | Can automatically label based on classification |
| Reporting | Provides detailed reports on incidents | Tracks labeled content for auditing |
In conclusion, the integration of DLP and classification labels in Microsoft 365 provides organizations with multifaceted approaches to information protection and governance. Leveraging these tools effectively ensures both preventive measures against data loss and structured handling of sensitive information. By doing so, companies can better meet compliance requirements, protect against data breaches, and secure their data throughout its lifecycle.

DLP policies are typically configured by IT administrators who have the necessary permissions to set up and manage these types of security measures.
True or False: Once a sensitivity label is published in Microsoft 365, it cannot be modified or deleted.
- Answer: False
Sensitivity labels in Microsoft 365 can be modified or deleted after being published, though changes may take time to propagate and may affect content previously labeled.
Sensitivity labels in Microsoft 365 use which of the following to help classify and protect documents and emails?
- A. Watermarks
- B. Headers
- C. Footers
- D. All of the above
Correct Answer: D. All of the above
