AWS Ansible Misconfiguration: EFS Missing Customer-Managed Encryption Key
Abstract
A configuration does not specify a customer-managed encryption key for data at rest.
Explanation
Customer-managed keys are not used to encrypt data at rest.
By default, AWS uses AWS-managed keys to encrypt data at rest if encryption is enabled. Customer-managed keys enable organizations to use cryptographic keys of their choice to encrypt data. This gives organizations better control over and logging of encryption processes.
As such, customer-managed keys are often part of the solution to address requirements that include but are not limited to:
- Audit logs for sensitive data access
- Data residency
- Replacing, disabling, or destroying keys
Note that keys with the format aws/service-name are reserved for AWS-managed keys.
