GCP Terraform Misconfiguration: Compute Engine Missing Customer-Managed Encryption Key
Abstract
A Compute Engine instance does not use a customer-supplied encryption key to protect the disk encryption key.
Explanation
By default, Google Cloud Compute Engine encrypts all data at rest. A customer-supplied encryption key (CSEK), if specified, encrypts the data encryption keys. Google does not store any CSEK on a Compute Engine instance and cannot access the protected data unless the correct CSEK is provided.
Example 1: The following example shows a Terraform Configuration that defines a persistent disk for a Compute Engine instance. The
Example 1: The following example shows a Terraform Configuration that defines a persistent disk for a Compute Engine instance. The
disk_encryption_key
block is missing so there is no CSEK to protect the data encryption keys.
