Specify TLS/SSL version used by certain port or protocol.

Some application only uses certain version of TLS/SSL. Due to vulnerabilities we don't want this TLS/SSL version to be available to all ports/protocol. We want an ability to specify which versions of TLS/SSL a port or protocol can and cannot use.

    Clients always use the highest protocol version and cipher they have in common with the server. The current versions of the protocols don't allow to use a lower cipher than supported.

    If a cipher or protocol version isn't secure, it should not be used on another protocol. The security is always as weak as the weakest link.

    HCL ensures current Ciphers and curves are supported. And older ciphers are marked as weak and are disabled by default.

    I don't see that splitting it between protocols would help.

    Rejecting this idea because the TLS protocol version should be the highest possible across the environment for security reasons.
