Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type Least privileged permissions Higher privileged permissions
Delegated (work or school account) CustomDetection.Read.All CustomDetection.ReadWrite.All
Delegated (personal Microsoft account) Not supported. Not supported.
Application CustomDetection.Read.All CustomDetection.ReadWrite.All

Important

For delegated access using work or school accounts, the signed-in user must be assigned a role that grants the permissions required for this operation. Custom detection rules use the Microsoft Defender XDR Unified role-based access control (RBAC) model. The following Microsoft Entra roles are supported:

  • Security Reader
  • Global Reader
  • Security Operator
  • Security Administrator

Additional workload-specific read permissions might be required to view rules that target data from specific Defender workloads (for example, Defender for Endpoint, Defender for Office 365). For more information, see Microsoft Defender XDR Unified RBAC.
