Infrastructure security in AWS Account Management
As managed services, AWS services running in your AWS account are protected by the
AWS global network security procedures that are described in the Amazon Web Services: Overview of Security Processes
You use AWS published API calls to access your account settings 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 using an access key ID and a secret access key that is associated with an IAM principal. You can also use the AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests.
