Encryption at rest

AWS IoT Greengrass stores your data:

Data at rest in the AWS Cloud

AWS IoT Greengrass encrypts customer data stored in the AWS Cloud. This data is protected using AWS KMS keys that are managed by AWS IoT Greengrass.

Data at rest on the Greengrass core

AWS IoT Greengrass relies on Unix file permissions and full-disk encryption (if enabled) to protect data at rest on the core. It is your responsibility to secure the file system and device.

However, AWS IoT Greengrass does encrypt local copies of your secrets retrieved from AWS Secrets Manager. For more information, see Secrets encryption.
