Tutorial / Cram Notes

Data Loss Prevention (DLP) policies are a critical element of a comprehensive information protection strategy. They enable organizations to identify, monitor, and automatically protect sensitive information across various services. Here’s how to configure DLP policies for a range of Microsoft services and on-premises repositories.

Microsoft Exchange Online

  1. Access the Security & Compliance Center: You’ll need to go to the Microsoft 365 compliance center. Sign in using your admin credentials.
  2. Create a DLP Policy: Navigate to ‘Policies’ -> ‘Data loss prevention’ and click on ‘+ Create a policy’.
  3. Choose Templates or Custom Policy: Select from existing templates or choose ‘Custom’ to create your own policy.
  4. Define Policy Settings: Configure the policy settings, including name, description, and locations to apply the policy. For Exchange, turn on the protection for emails.
  5. Set Rules: Define the conditions and actions. You can use conditions like the content containing certain sensitive information or when attachments are detected.
  6. Deploy the Policy: Test, fine-tune, and then enable the policy. You can start with the policy in test mode to understand its impact.

Microsoft SharePoint Online and Microsoft OneDrive

  1. Access the Security & Compliance Center: As with Exchange Online, start at the Microsoft 365 compliance center.
  2. Create or Modify a DLP Policy: Either create a new policy or edit an existing one, to include SharePoint Online and OneDrive for Business.
  3. Choose Locations: When setting up the policy, choose to protect items in SharePoint and OneDrive.
  4. Define Scope: You can define the scope to include all sites or specific sites.
  5. Customize Rules and Notifications: Customize the rules for what content to detect and what actions to take, such as blocking access or sending notifications.
  6. Enforcement: After testing and tuning, deploy the policy to start enforcing the rules.

Microsoft Teams

  1. Access the Compliance Center: Microsoft Teams DLP is managed through the same Security & Compliance Center.
  2. Create or Edit a DLP Policy: Integrate Teams into your DLP strategy by including it in your policy locations.
  3. Set up Chat and Channel Policies: Define the rules for private chats or channel conversations within Teams.
  4. Configure Notifications: Set up notifications and tips to users when they’re about to violate a policy.
  5. Test and Deploy: Test the impact of your DLP policy on Teams communication and adjust as necessary before full deployment.

Microsoft PowerBI

  1. Access PowerBI Settings: Go to PowerBI Service and navigate to the admin portal.
  2. Apply DLP to Datasets: Data Loss Prevention in PowerBI is slightly different. You need to work with Information Rights Management (IRM) and sensitivity labels.
  3. Configure Sensitivity Labels in Microsoft 365 Compliance Center: Use the compliance center to create and manage sensitivity labels, then apply them to PowerBI content.
  4. Monitor and Audit: Use PowerBI’s auditing features to monitor how data is shared and exported.

On-premises Repositories

  1. Integrate with Microsoft 365: Use the Microsoft Data Protection Manager or a third-party tool to integrate your on-premises repositories with Microsoft 365 compliance solutions.
  2. Use Microsoft 365 DLP Policies: You can extend DLP controls to on-premises solutions by ensuring that the data is identified and classified in line with your Microsoft 365 DLP policies.
  3. Monitor with AIP Scanner: The Azure Information Protection (AIP) scanner can be deployed to scan on-premises repositories, automatically classifying and protecting files according to your DLP policies.

Implementing DLP Across Services: Comparing Characteristics

Service Detection Capabilities Location Control Custom Rules Notifications and Tips Test Mode
Exchange Online Emails, attachments Mailboxes Yes Yes Yes
SharePoint Files, documents Sites, libraries Yes Yes Yes
OneDrive Files, personal storage User level Yes Yes Yes
Teams Chats, channels Teams chats Yes Yes Yes
PowerBI Datasets, reports Dashboards No Via IRM/sensitivity No
On-premises Files, databases Servers Yes Limited by integration Depending

When configuring DLP policies in these environments, always keep in mind the context of the data, user behavior, and business processes to minimize false positives and ensure that security measures don’t hinder productivity. Regularly review and update policies to adapt to new compliance requirements or business needs.

Remember that proactive DLP policy enforcement across various platforms is critical for protecting sensitive information and meeting regulatory compliance standards, an essential skill for the Microsoft Information Protection Administrator and a requirement for successful completion of the SC-400 exam.

Interview Questions

What is DLP and how does it work in Microsoft 365?

DLP stands for Data Loss Prevention and it is a feature in Microsoft 365 that helps prevent the accidental or intentional disclosure of sensitive information. It works by using policies to identify and protect sensitive data, and by providing alerts and actions when potential violations are detected.

How do you create a DLP policy in Microsoft 365?

To create a DLP policy in Microsoft 365, you can go to the Compliance center and navigate to the Data loss prevention page. From there, you can choose to create a new policy and then specify the locations and conditions to which the policy will apply.

What types of data can be protected with DLP policies in Microsoft 365?

DLP policies in Microsoft 365 can be used to protect a wide range of data types, including financial data, personal identifiable information (PII), and confidential business information.

How can DLP policies be configured to work with Microsoft Exchange Online?

DLP policies can be configured to work with Microsoft Exchange Online by specifying the email messages, attachments, and other data that should be checked for sensitive information, and by defining the conditions that will trigger policy violations.

Can DLP policies be applied to Microsoft SharePoint Online and Microsoft OneDrive?

Yes, DLP policies can be applied to both Microsoft SharePoint Online and Microsoft OneDrive. These policies can be used to scan files and documents for sensitive information and to take actions when policy violations are detected.

How can DLP policies be configured to work with Microsoft Teams?

What is the difference between a default policy and a custom policy in Microsoft 365 DLP?

The default DLP policy in Microsoft 365 provides a basic set of rules for detecting and preventing sensitive data loss. Custom DLP policies, on the other hand, are designed to meet the specific needs of an organization and can be tailored to the unique data protection requirements of the organization.

Can DLP policies be configured to work with on-premises repositories?

Yes, DLP policies can be configured to work with on-premises repositories using the DLP scanner. This allows organizations to apply DLP policies to data that is stored on-premises and to integrate that data with the DLP policies in Microsoft 365.

How can DLP policies be tested and tuned in Microsoft 365?

DLP policies can be tested and tuned in Microsoft 365 by using the Policy tips feature, which provides real-time alerts and actions when potential policy violations are detected. This allows organizations to fine-tune their policies to reduce false positives and to improve their overall effectiveness.

What is the role of reporting and analytics in DLP policies in Microsoft 365?

Reporting and analytics are important components of DLP policies in Microsoft 365 because they allow organizations to monitor and track policy violations, to identify areas for improvement, and to demonstrate compliance with regulatory requirements.
