Infrastructure security in Amazon Resource Explorer
As a managed service, Resource Explorer is protected by the Amazon global network security
procedures that are described in the Amazon Web Services: Overview of Security Processes
You use Amazon published API calls to access Resource Explorer through the network. Clients must support Transport Layer Security (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 use the Amazon Security Token Service (Amazon STS) to generate temporary security credentials with the required keys to sign requests.
