name: No Customer-Managed Encryption Keys in Google Cloud Functions
|
|
author: princechaddha
|
|
severity: high
|
|
description: |
|
|
Ensure that your Google Cloud functions use Customer-Managed Encryption Keys (CMEK) instead of Google-managed encryption keys to encrypt data at rest. CMEKs provide greater control over the encryption and decryption process, enabling you to meet stringent compliance requirements.
|
|
impact: |
|
|
Using Google-managed encryption keys instead of CMEKs reduces your ability to control the encryption process and comply with certain regulatory standards.
|
|
remediation: |
|
|
Configure your Google Cloud functions to use Customer-Managed Encryption Keys (CMEK) to ensure data encryption at rest is managed according to your compliance and security requirements.
