Create cloudFirewallPolicy

Namespace: microsoft.graph.networkaccess

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Create a new cloudFirewallPolicy object.

This API is available in the following national cloud deployments.

Global service	US Government L4	US Government L5 (DOD)	China operated by 21Vianet
✅	❌	❌	❌

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)	NetworkAccess.ReadWrite.All	Not available.
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	NetworkAccess.ReadWrite.All	Not available.

Important

For delegated access using work or school accounts, the signed-in user must be assigned a supported Microsoft Entra role or a custom role that grants the permissions required for this operation. This operation supports the following built-in roles, which provide only the least privilege necessary:

• Global Secure Access Administrator
• Security Administrator
