Enforce certificate-based access with VPC Service Controls

To protect Google Cloud services in your projects and mitigate the risk of data exfiltration, you can specify VPC Service Controls service perimeters at an organization, folder, or project level. Applying a service perimeter provides you with fine-grained control over the ingress policy as well as which services and resources to protect.

For more information about the benefits of service perimeters, see Overview of VPC Service Controls .

Applying a CBA ingress policy to service perimeters

Applying CBA access levels to service perimeters allows you to grant access to perimeter-protected resources from only trusted devices. For more information about creating a CBA access level, see Create access levels for certificate-based access .

The following diagram illustrates a basic example of restricting access to Cloud Storage sensitive data from unknown devices by associating a CBA access level with a service perimeter:
