Tutorial / Cram Notes
Data Loss Prevention (DLP) policies are an integral part of protecting sensitive data across your organization’s cloud environment, especially when using Microsoft Defender for Cloud Apps. DLP policies help ensure that the data your organization considers sensitive does not leave your cloud environments in an unauthorized manner.
To configure DLP policies for use in Microsoft Defender for Cloud Apps, you would need to follow these steps:
Understand Your Sensitive Information Types
Before you configure a DLP policy, identify the types of sensitive information that require protection, such as credit card numbers, social security numbers, or proprietary business data.
Set Up Microsoft Defender for Cloud Apps
- Access Microsoft Defender for Cloud Apps: Log in to the Microsoft Defender Security Center and navigate to the “Cloud Apps” section.
- Integration with Data Sources: Ensure that Microsoft Defender for Cloud Apps is connected to the cloud services you use, such as Microsoft 365, G Suite, Salesforce, etc.
Create a DLP Policy
- Navigate to the Control section: Once in the Cloud Apps dashboard, go to the “Control” section and then to the “Policies” tab.
- Create a New Policy: Click on “+ Create policy” and select “Data Loss Prevention” as the type of policy you want to create.
Configure Policy Settings
- Policy Name: Enter a descriptive name for the policy.
- Policy Severity: Choose a severity level for incidents that match the policy.
- Policy Category: Assign a category such as Compliance or Data Protection.
- Protected Apps: Specify which applications the policy should apply to.
Define Policy Conditions
- Content Inspection: Define which types of content you want to inspect for sensitive information using built-in or custom sensitive information types.
- Filters and Scopes: Apply filters to specify user groups, network locations, or device types where the policy will apply.
Set Policy Actions
- Alerts: Configure alerts to notify administrators of policy matches.
- Governance Actions: Determine what actions to take when a match is found, including options like making the file private, removing a collaborator, or blocking access entirely.
Set Up Notifications and User Warnings
- User Notifications: Create notification messages to warn users when their actions violate a DLP policy.
- User Tips: Give users tips on how to comply with company data protection policies.
Review and Test Your Policy
- Policy Logic: Review the policy to ensure it aligns with your organization’s data protection needs.
- Test Mode: Consider setting the policy to test mode initially to understand the policy’s impact without affecting end-users.
Enable and Monitor the Policy
- Enable Policy: Once the policy is finalized, set it to “On” status to enforce it.
- Monitor Incidents: Regularly check the incident reports to fine-tune your DLP policies based on real-world data.
Example
Here’s an example policy for protecting credit card information:
- Policy Name: Credit Card Information Protection
- Severity: High
- Category: Compliance
- Protected Apps: Microsoft Teams, SharePoint Online, and Exchange Online
- Content Inspection: Built-in sensitive information type for Credit Card Number
- Filters and Scopes: Apply to all users except for the finance department
- Governance Actions: Block external sharing and alert admins
- User Notifications: Notify users when they attempt to share credit card information externally
- Test Mode: Initially in test mode to gauge impact
Conclusion
Intelligently designed DLP policies are essential for protecting sensitive information and maintaining compliance in the cloud. By leveraging Microsoft Defender for Cloud Apps capabilities and setting up thoughtful policies, organizations can significantly minimize the risk of data loss.
It’s crucial to keep in mind that DLP policies are not a set-and-forget measure; they should be continually reviewed and updated based on organizational changes, evolving threats, and feedback from the monitoring process.
