Amazon EFS supports two forms of encryption for file systems, encryption of data in transit and encryption at rest. You can enable encryption of data at rest when creating an Amazon EFS file system. You can enable encryption of data in transit when you mount the file system.
If you require FIPS 140-2 validated cryptographic modules when accessing AWS through a
command line interface or an API, use a FIPS endpoint. For more information about the available
FIPS endpoints, see Federal Information Processing Standard (FIPS) 140-2
If your organization is subject to corporate or regulatory policies that require encryption of data and metadata at rest, we recommend creating a file system that is encrypted at rest, and mounting your file system using encryption of data in transit.
