Description

The default settings currently seem to allow weak TLS ciphers & protocols. These can be changed in the settings (using enabled_ciphers and enabled_protocols) to harden them, but we should consider changing the default in the upcoming 3.0 release (as it’d be a breaking change)?

Considering following the configuration from Mozilla (note: “intermediate” is required for java 8 compatibility, need to check if we're dropping that with OpenSearch 3.0):

Research direction

Start by locating the defaults for enabled_ciphers and enabled_protocols, then compare them with Mozilla's intermediate TLS configuration. Check the Java 8 compatibility note and whether OpenSearch 3.0 drops that requirement. Done means selecting and documenting stronger defaults with the compatibility and breaking-change decision resolved.
