Tutorial / Cram Notes
Data loss prevention (DLP) policies in Microsoft 365 serve as a safeguard to detect and protect sensitive information across the organization’s Office 365 services, like Exchange Online, SharePoint Online, and OneDrive for Business. However, there are instances when DLP policy violations occur, necessitating remediation. In the context of an SC-400 Microsoft Information Protection Administrator certification, understanding how to handle these violations is crucial.
Remediation of data loss prevention policy violations within the Microsoft 365 compliance center involves several steps and capabilities designed to protect sensitive information while minimizing disruption to productivity.
Investigation of DLP Incidents
Firstly, when a potential DLP incident occurs, it’s registered in the Microsoft 365 compliance center, where it can be reviewed by the compliance team. Administrators can go to the DLP section to get detailed report information on the policy that was violated, the content that triggered the violation, and the context in which it happened.
Reviewing and Assessing the Incident
Upon identifying an incident, the team must assess its severity. This evaluation often includes reviewing:
- Who accessed, shared, or tried to share the sensitive information
- Why the DLP policy was triggered (keywords, content, etc.)
- The content’s location (e.g., SharePoint site, Exchange email)
- The potential impact of the data exposure
Examples of Policy Violation Insights
| Violation Detail | Example |
|---|---|
| User | [email protected] |
| Detected Content | Credit Card Number |
| Policy Triggered | Credit Card Information Leakage Policy |
| Location | SharePoint Document Library |
| Action Taken | Access Blocked |
Taking Remediation Actions
After the incident has been assessed, several remediation actions are available:
- Notification: Inform the user who caused the violation about the incident, providing guidance on how to handle the sensitive information correctly. Notifications can also be sent to the compliance team.
- Override: In some cases, users with proper justification can override a DLP policy block if they have the required permissions and provide a business justification.
- Incident reports: Detailed reports should be generated for auditing and compliance purposes, recording all necessary details of the incident and the actions taken in response.
- Policy modification: If a recurring issue arises or the policy is too restrictive or too lax, the DLP policy itself may need to be adjusted.
Examples of Remediation Actions
| Action | Description | Example |
|---|---|---|
| Notify User | Send a notification to the user with guidance | Email alert to user with DLP policy explanation |
| Override | Allow user to bypass the policy with justification | User provides valid business reason to share sensitive data |
| Incident Report | Document details of the violation and actions taken | Creation of an audit report for compliance records |
| Policy Modification | Adjust the DLP policy to prevent future false positives/negatives | Updating policy rules to refine sensitive information types or exclusion criteria |
Automating Remediation Processes
Automation can significantly improve the efficiency and consistency of handling DLP policy violations. In the compliance center, administrators can set up automated responses that take action when certain conditions of a DLP policy violation are met, such as:
- Automatically blocking access to the sensitive content
- Removing sharing permissions
- Quarantining an email until reviewed by the compliance team
Monitoring and Analytics
Continuous monitoring of DLP policies and incidents is essential. To aid in this:
- Use analytics to spot trends in DLP incidents to proactively adjust policies
- Monitor user behavior to identify potential risks or training needs
- Refine DLP policies based on the insights gained from monitoring and analytics
By following a structured approach to investigating, assessing, and remediating DLP incidents, organizations using Microsoft 365 can effectively handle policy violations. Ensuring all measures align with the organization’s compliance requirements and business operations is necessary for maintaining data security without limiting productivity.
As an SC-400 Information Protection Administrator, mastering these procedures and leveraging the tools available in the Microsoft 365 compliance center to remediate DLP policy violations is a critical skill that helps to uphold the integrity and protection of sensitive organizational data.
Practice Test with Explanation
True or False: Data loss prevention (DLP) policies in Microsoft 365 Compliance Center can help protect sensitive information across Exchange Online, SharePoint Online, and OneDrive for Business.
- True
Correct Answer: True
Explanation: DLP policies in Microsoft 365 can help identify, monitor, and protect sensitive information across these services.
A DLP policy violation occurs when which of the following happens?

- B) An employee accesses a file they are authorized to view.
- C) Sensitive information is shared in a way that violates the policy rules.
- D) All of the above.
Correct Answer: C) Sensitive information is shared in a way that violates the policy rules.
Explanation: DLP policy violations occur when sensitive information is shared or handled in a manner that is against the rules defined in the policy.
True or False: When a DLP policy violation is detected, Microsoft 365 can automatically block access to the content until the issue is remediated.
- True
Correct Answer: True
Explanation: Microsoft 365 can be configured to automatically restrict access to the sensitive content when a DLP policy violation is detected, to prevent further potential leakage.
Who can receive notifications when a DLP policy violation occurs?
- A) The content owner only
- B) The person who last modified the content
- C) The policy administrator
