Infrastructure security in Amazon Chime
As a managed service, Amazon Chime 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 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.
