Configuring DLP policies for Microsoft Teams

Data Loss Prevention (DLP) in Microsoft Teams, as well as the larger DLP story for Microsoft 365 or Office 365, revolves around business readiness when it comes to protecting sensitive documents and data. Whether you have concerns around sensitive information in messages or documents, DLP policies will be able to help ensure your users don't share this sensitive data with the wrong people. In this interactive guide, you will learn how to add Microsoft Teams to an existing DLP policy, as well as create a new policy, whether based on a template or fully customized to your organziation's data protection needs.

Exercise 1: Add Microsoft Teams as a location to an existing policy

In this exercise, you will use the Microsoft 365 Compliance admin center to edit an existing DLP policy, adding Microsoft Teams as a location to which the policy will apply.

The exercise begins in the M365 admin center ( logged in as the administrator of Contoso.

Exercise 2: Create a new DLP Policy from a template

In this example, you will create a new DLP policy starting with a template. By starting with a DLP template, you save the work of building a new set of rules from scratch, and figuring out which types of information should be included by default. You can then add to or modify these requirements to fine tune the rule to meet your organization's specific requirements.

Exercise 3: Create a new custom DLP Policy

In this exercise, you will learn how to create a DLP policy based on a custom sensitive info type to protect against disclosure of sensitive information pertaining to a confidential project.   

Part 1: Create a custom sensitive info type for the Mark 8 project

Part 2: Create a custom policy

Exercise 4: End User Experience and Reporting

In this exercise, you will see the Microsoft Teams user experience for the custom DLP policy you created in exercise 3.    You will then learn how to use the Microsoft 365 compliance admin center to access reports on DLP policy matches and incidents.

Part 1: Teams user experience

Part 2: Admin reporting experience

Now, we willl switch to the administrator perspective to access the reports corresponding to Megan’s message, as well as other DLP policy matches in the organization.
