Microsoft’s DLP solution comes with comprehensive reporting capabilities that provide in-depth insights into data loss incidents, helping administrators tighten their information security. DLP reports are available in the Security & Compliance Center in Microsoft 365. Understanding these reports can help the SC-400 Microsoft Information Protection Administrator test-takers manage and secure sensitive data more effectively.
Understanding Data Loss Prevention Reports
Microsoft offers several pre-defined DLP reports, each offering its unique insights:
- DLP Policy Matches Report: This report displays the total count of DLP rule matches for a specified date range. It helps understanding which policies are triggered most frequently.
- DLP Incident Report: This report provides detailed information about data loss incidents detected by the DLP policies. It lists the sender, recipient, date and time, rule, policy, and confidence level for each incident.
- DLP False Positives and Negatives Report: This report helps monitor the effectiveness of DLP policies by showing false positives and negatives.
To view these reports, navigate to the Security & Compliance Center, select Reports > Dashboard, then select the DLP report you want to view.
Analyzing Data Loss Prevention Reports
Analyzing DLP reports involves reviewing the data and identifying trends or abnormalities. For instance, if a particular policy is triggered frequently, it may indicate that users are not aware of the policy or that it is too broad and needs to be refined.
Here is an example: a sudden increase in DLP policy matches related to financial data might indicate either a targeted phishing attempt to steal financial information or an internal user who is unaware that this information should not be emailed.
Let’s say the DLP Incident Report shows an employee sent credit card information to a personal email address. Although the DLP policy prevented the email from being sent, it’s important to educate the employee about the policy and the potential risks associated with such actions.
Enhancing DLP Reporting with Advanced Features
Microsoft provides additional features to enhance DLP reporting:
- Filtering: To focus on specific data, use filters. For instance, you can filter by date range, location (such as Exchange, OneDrive, SharePoint), rule, or severity level.
- Exporting: To analyze the data using external tools or share it with others, you can export the report data to a CSV file.
- Alerts: You can configure alerts to be notified about specific incidents or when the number of incidents reaches a certain threshold. This can be done in the Microsoft 365 compliance center under the “Alerts” area.
Power BI and DLP Reports
Power BI, a business analytics solution by Microsoft, can also be used to analyze DLP reports. It provides advanced data visualization and analytical capabilities, helping administrators find trends and patterns. With Power BI, you can create interactive dashboards and reports with drill-down capabilities.
Conclusion
DLP reports are a valuable tool for all Information Protection Administrators, especially those preparing for the SC-400 exam. They provide insights into where and how sensitive data is being used or misused, enabling better decision-making and more effective policy implementation. By regularly reviewing and analyzing these reports, administrators can greatly enhance data security.

- C. Exclude the false positives from future scans
- D. Both B and C
Answer: D. Both B and C
Explanation: If a high number of false positives are found, you can modify the DLP policies to better align with the actual risk and/or exclude the confirmed false positives from future scans.
True or False: DLP reports in Microsoft 365 provide real-time data.
- True
- False
Answer: False
Explanation: DLP reports do not provide real-time data. They show data that’s up to 24 hours old.
What is the primary objective of analyzing data loss prevention reports?

- D. All of the above
Answer: D. All of the above
Explanation: The primary objective of analyzing DLP reports is to gain visibility into where sensitive information is stored, understand how this information is shared, and track DLP rule matches and incidents.
True or False: False negatives are potential violations that your DLP policies overlooked.
- True
- False
Answer: True
Explanation: False negatives are indeed potential violations that DLP policies did not catch, and they pose a significant risk because sensitive data continues to be exposed without detection.

Interview Questions
What does the term ‘data loss prevention’ mean?
Data loss prevention (DLP) refers to strategies, processes, and tools used to ensure that sensitive data is not lost, misused, or accessed by unauthorized users.
Why are data loss prevention reports significant?
DLP reports are critical because they provide detailed insights into data usage trends, potential risks, and violations, hence facilitating the decision-making process for enhancing security.
What are some common components found in a data loss prevention report?
Information usually found in DLP reports includes details about matches for sensitive content, occurrences of policy violations, information about false positives and false negatives, and data about user activities related to sensitive information.
What is the purpose of the content explorer in DLP?
The content explorer provides insights into what content matches DLP policy rules, and where this content is located. This helps administrators investigate and resolve DLP policy matches.
What is the primary role of a Microsoft Information Protection Administrator in relation to DLP reports?
The Microsoft Information Protection Administrator is responsible for managing and analyzing DLP reports to help determine the organization’s risk posture, ensure compliance with DLP policies, and take necessary actions based on the insights derived from the reports.
What is the Incident Management dashboard in DLP?
The Incident Management dashboard provides a detailed overview of all DLP policy violations. This helps in understanding where sensitive information is being used, how it’s being shared, and if policy violations have occurred.
Mention some reliable procedures of preventing data loss.
These include regular data backups, implementing strong access control measures, DLP policy execution, deploying reliable security software, and continuous employee training on secure data handling practices.
What is a false positive in DLP reporting?
A false positive in DLP reporting refers to an instance where the DLP system incorrectly signals that sensitive data has been compromised when it hasn’t.
How can a Microsoft Information Protection Administrator reduce the number of false positives in DLP reports?
To reduce the number of false positives, an administrator can ensure realistic and accurate policy rules, leverage machine learning capabilities, and continually fine-tune DLP policies based on outcomes from previous reports.
What can be effected through the activity explorer in DLP?
Activity explorer can be used to view and investigate user and item-level activities that match your DLP policies. This helps to understand more about how sensitive content is being used and shared in your organization.
What are the steps to create a DLP policy in Microsoft 365 compliance center?
Steps include going to the Microsoft 365 compliance center, creating a new policy, choosing the locations where to apply the policy, adding conditions, choosing actions for policy violations, testing the policy, and finally deploying it.
What is a DLP policy rule in Microsoft 365?
A data loss prevention (DLP) policy rule in Microsoft 365 is a component of a DLP policy that specifies conditions that data must meet, and actions to take when data that meets those conditions is detected.
How can one generate a DLP report in Microsoft 365?
DLP reports can be generated from the Microsoft 365 compliance center. Reports can be custom generated based on the need, and can include details of sensitive information detected, actions taken, and the detection source.
What is a false negative in DLP reporting?
A false negative in DLP reporting refers to an instance where the DLP system does not flag a genuine data compromise or violation.
How do DLP reports assist in regulatory compliance?
DLP reports help to demonstrate that the organization has implemented effective measures to protect sensitive data, thus providing evidence of compliance with regulatory requirements such as GDPR, HIPAA etc. These reports can also identify areas of non-compliance for rectification.
