Infrastructure security in AWS Outposts
As a managed service, AWS Outposts is protected by the AWS global network security procedures.
You use AWS published API calls to access AWS Outposts 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. Or you can use the AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests.
For more information about the infrastructure security provided for the EC2 instances and EBS volumes running on your Outpost, see Infrastructure Security in Amazon EC2.
VPC Flow Logs function the same way as they do in an AWS Region. This means that they can be published to CloudWatch Logs, Amazon S3, or to Amazon GuardDuty for analysis. Data needs to be sent back to the Region for publication to these services, so it is not visible from CloudWatch or other services when the Outpost is in a disconnected state.
