Infrastructure security in AWS CloudShell
As a managed service, AWS CloudShell is 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 AWS CloudShell through the network. Clients must support Transport Layer Security (TLS) 1.2 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 by using an access key ID and a secret access key that's associated with an IAM principal. Or you can use the AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests.
By default, AWS CloudShell automatically install security patches for the system packages of your compute environments.
