Infrastructure security in AWS IoT SiteWise - AWS IoT SiteWise

Infrastructure security in AWS IoT SiteWise

As a managed service, AWS IoT SiteWise is protected by AWS global network security. For information about AWS security services and how AWS protects infrastructure, see AWS Cloud Security. To design your AWS environment using the best practices for infrastructure security, see Infrastructure Protection in Security Pillar AWS Well‐Architected Framework.

You use AWS published API calls to access AWS IoT SiteWise 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.

SiteWise Edge gateways, which run on AWS IoT Greengrass, 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 in the AWS IoT Greengrass Version 1 Developer Guide.
