By default, the S3 Gateway service supports the Transport Layer Security (TLS) 1.2 and 1.3 protocols to establish secure links to client nodes. TLS uses a suite of cryptographic algorithms to provide security for HTTPS traffic. The default cipher suite used by the S3 Gateway service is the Open Web Application Security Project (OWASP) security recommendation for Tomcat. You can provide your own cipher suite.
Note: Contact Support if you need to use the TLS 1.0 or 1.1 protocols.
