Infrastructure security in AWS Application Migration Service

As a managed service, AWS Application Migration Service 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 AWS Application Migration Service 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.

All parties involved in the communication authenticate each other using TLS, IAM policies and tokens. The communication between the Agents and the replication server are based on TLS 1.2 only with the highest standard of cipher suite (PFS, ECDHE. Requests between the agent and AWS Application Migration Service as well as between the replication server and Application Migration Service are signed using an access key ID and a secret access key that is associated with an IAM principal).

All requests must be signed using the AWS Security Token Service (AWS STS), which allows you to generate temporary security credentials to sign requests. Alternatively, use credentials that associated with an IAM principal.

AWS Application Migration Service customers must ensure that they manually delete their access keys after installing the AWS Replication Agent and successful migration. AWS does not delete these keys automatically. AWS Application Migration Service does delete the keys from source servers after they are disconnected from the service. If you want your keys to automatically stop working at a certain date after you have finished using them so that you do not have to worry about manually deleting them, you can do so though the IAM permissions boundary and the aws:CurrentTime global context key.

AWS Application Migration Service customers should use Amazon EBS encryption.

AWS Application Migration Service customers should secure their replication servers by reducing their exposure to the public internet. This can be done through:

AWS Application Migration Service creates and uses the "aws-replication" user within the Linux Source server. The AWS Application Migration Service replication server and AWS Replication Agent run under this user. Although this is not a root user, this user needs to be part of the disk group that grants this user full read and write permissions to block devices.
