Data loss prevention activity logging

Data loss protection (DLP) policy activities are tracked from the Microsoft 365 Security and Compliance Center.

To log DLP activities, follow these steps:

  1. Sign in to the Security & Compliance center as a tenant admin.

  2. Select Search > Audit log search.

  3. Under Search > Activities, enter dlp. A list of activities appears.

    Screenshot showing audit log search DLP policies.

  4. Select an activity, select outside the search window to close it, and then select Search.

On the Audit log search screen, you can search audit logs across many popular services including eDiscovery, Exchange, Power BI, Azure Active Directory (Azure AD), Microsoft Teams, customer engagement apps (Dynamics 365 Sales, Dynamics 365 Customer Service, Dynamics 365 Field Service, Dynamics 365 Marketing, and Dynamics 365 Project Service Automation), and Microsoft Power Platform.

After you access Audit log search, you can filter for specific activities by expanding Activities and then scrolling to find the section dedicated to Microsoft Power Platform activities.

What DLP events are audited

The following are the user actions you can audit:

  • Created DLP Policy: When a new DLP policy is created
  • Updated DLP Policy: When an existing DLP policy is updated
  • Deleted DLP Policy: When a DLP policy is deleted

Base schema for DLP audit events

Schemas define which fields are sent to the Microsoft 365 Security and Compliance Center. Some fields are common to all applications that send audit data to Microsoft 365, while others are specific to DLP policies. In the following table, Name and Additional Info are the DLP policy–specific columns.

Field name Type Mandatory Description
Date Edm.Date No Date and time of when the log was generated in UTC
App Name Edm.String No Unique Identifier of the PowerApp
Id Edm.Guid No Unique GUID for every row logged
Result Status Edm.String No Status of the row logged. Success in most cases.
Organization Id Edm.Guid Yes Unique identifier of the organization from which the log was generated.
CreationTime Edm.Date No Date and time of when the log was generated in UTC
Operation Edm.Date No Name of operation
UserKey Edm.String No Unique Identifier of the User in Azure AD
UserType Self.UserType No The audit type (Admin, Regular, System)
Additional Info Edm.String No Additional information if any (e.g. the environment name)

Additional Info

The Additional Info field is a JSON object that contains operation-specific properties. For a DLP policy operation, it contains the following properties.

Field name Type Mandatory? Description
PolicyId Edm.Guid Yes The GUID of the policy.
PolicyType Edm.String Yes The policy type. Allowed values are AllEnvironments, SingleEnvironment, OnlyEnvironments, or ExceptEnvironments.
DefaultConnectorClassification Edm.String Yes The default connector classification. Allowed values are General, Blocked, or Confidential.
EnvironmentName Edm.String No The name (GUID) of the environment. This is only present for SingleEnvironment policies.
ChangeSet Edm.String No Changes made to the policy. These are only present for update operations.

The following is an example of the Additional Info JSON for a create or delete event.

{ 
  "policyId": "eb1e0480-0fe9-434e-9ad8-df4047a666ec", 
  "policyType": "SingleEnvironment", 
  "defaultConnectorClassification": "General", 
  "environmentName": "8a11a4a6-d8a4-4c47-96d7-3c2a60efe2f5" 
} 

The following is an example of the Additional Info JSON for an update operation that:

  • Changes the policy name from oldPolicyName to newPolicyName.
  • Changes the default classification from General to Confidential.
  • Changes the policy type from OnlyEnvironments to ExceptEnvironments.
  • Moves the Azure Blob Storage connector from the General to the Confidential bucket.
  • Moves the Bing Maps connector from the General to the Blocked bucket.
  • Moves the Azure Automation connector from the Confidential to the Blocked bucket.
