Faster AWS cloud connections with TLS 1.3

Post Syndicated from Kate Rodgers original https://aws.amazon.com/blogs/security/faster-aws-cloud-connections-with-tls-1-3/

At Amazon Web Services (AWS), we strive to continuously improve customer experience by delivering a cloud computing environment that supports the most modern security technologies. To improve the overall performance of your connections, we have already started to enable TLS version 1.3 globally across our AWS service API endpoints, and will complete this process by December 31, 2023. By using TLS 1.3, you can decrease your connection time by removing one network round trip for every connection request, and can benefit from some of the most modern and secure cryptographic cipher suites available today.

If you are using current software tools (2014 or later) including our AWS SDKs or AWS Command Line Interface (AWS CLI), you will automatically receive the benefits of TLS 1.3 with no action required on your part. This is because AWS services will negotiate the highest TLS protocol version that your client software supports. If you want to continue using TLS 1.2, you will still have full control through your client configurations. AWS will retain support for TLS 1.2, in addition to TLS 1.3, into the foreseeable future. Meanwhile, here’s the latest information on the on-going deprecation of TLS 1.0/1.1.
