Infrastructure security in Amazon IoT SiteWise

As a managed service, Amazon IoT SiteWise is protected by the Amazon global network security procedures that are described in the Amazon Web Services: Overview of Security Processes whitepaper.

You use Amazon published API calls to access Amazon IoT SiteWise through the network. Clients must support Transport Layer Security (TLS) 1.0 or later. We recommend TLS 1.2 or later. Clients must also support cipher suites with perfect forward secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Ephemeral Diffie-Hellman (ECDHE). 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 Amazon Security Token Service (Amazon STS) to generate temporary security credentials to sign requests.

Amazon IoT SiteWise gateways, which run on Amazon IoT Greengrass, use X.509 certificates and cryptographic keys to connect and authenticate to the Amazon Cloud. For more information, see Device authentication and authorization for Amazon IoT Greengrass in the Amazon IoT Greengrass Version 1 Developer Guide.
