name: VM Disk Encryption with Customer-Supplied Keys Disabled
|
|
author: princechaddha
|
|
severity: high
|
|
description: |
|
|
Ensure that the disks attached to your production Google Compute Engine instances are encrypted with Customer-Supplied Encryption Keys (CSEKs) in order to have complete control over the data-at-rest encryption and decryption process, and meet strict compliance requirements.
|
|
impact: |
|
|
Without CSEK encryption, you have limited control over the encryption process of your VM disk data, which may not meet strict compliance requirements for sensitive data protection.
|
|
remediation: |
|
|
Enable Customer-Supplied Encryption Keys (CSEKs) for your VM disks by providing a valid encryption key during disk creation or instance launch. The key must be a 256-bit string encoded in RFC 4648 base64 format.
