AWS IoT Greengrass Version 1 entered the extended life phase on June 30, 2023. For more information, see the AWS IoT Greengrass V1 maintenance policy. After this date, AWS IoT Greengrass V1 won't release updates that provide features, enhancements, bug fixes, or security patches. Devices that run on AWS IoT Greengrass V1 won't be disrupted and will continue to operate and to connect to the cloud. We strongly recommend that you migrate to AWS IoT Greengrass Version 2, which adds significant new features and support for additional platforms.
Infrastructure security in AWS IoT Greengrass
As a managed service, AWS IoT Greengrass is protected by AWS global network security. For information about AWS security services and how AWS protects infrastructure, see AWS Cloud Security
You use AWS published API calls to access AWS IoT Greengrass through the network. Clients must support the following:
-
Transport Layer Security (TLS). We require TLS 1.2 and recommend TLS 1.3.
-
Cipher suites with perfect forward secrecy (PFS) such as DHE (Ephemeral Diffie-Hellman) or ECDHE (Elliptic Curve Ephemeral Diffie-Hellman). Most modern systems such as Java 7 and later support these modes.
Additionally, requests must be signed by using an access key ID and a secret access key that is associated with an IAM principal. Or you can use the AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests.
In an AWS IoT Greengrass environment, devices use X.509 certificates and cryptographic keys to connect and authenticate to the AWS Cloud. For more information, see Device authentication and authorization for AWS IoT Greengrass.
