Object Storage supports secure client-server data exchange via the Transport Layer Security (TLS) protocol. To ensure robust protection of your data exchange, use TLS version 1.2 or higher.
Currently, Object Storage supports TLS 1.0 and 1.1; however this support will be discontinued moving forward, although no issues or vulnerabilities have been detected.
Most Amazon S3-compatible Object Storage clients do not allow you to explicitly select the TLS version; instead, they use the version specified at the system level.
To learn how to configure your clients for TLS 1.2, see these AWS guides:
