Infrastructure security in Managed Service for Apache Flink

As a managed service, Managed Service for Apache Flink is protected by the AWS global network security procedures that are described in the Amazon Web Services: Overview of Security Processes whitepaper.

You use AWS published API calls to access Managed Service for Apache Flink through the network. All API calls to Managed Service for Apache Flink are secured via Transport Layer Security (TLS) and authenticated via IAM. Clients must support 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 AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests.
