Infrastructure security in Amazon WorkMail
Note
Amazon WorkMail discontinued support for Transport Layer Security (TLS) 1.0 and 1.1. If you are using TLS 1.0 or 1.1, you must upgrade the TLS version to 1.2. For more information, see TLS 1.2 to become the minimum TLS protocol level for all AWS API endpoints
As a managed service, Amazon WorkMail 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 Amazon WorkMail 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.
