Disable insecure TLS versions


The system must disable out-of-date or insecure versions of SSL and TLS protocols, algorithms and ciphers.


All communications between the client and the server should take place over channels that are protected and encrypted. In order to guarantee this, out-of-date or insecure protocols such as SSLv2, SSLv3, or TLS 1.0 and TLS 1.1 should be disabled. The latest version of TLS should be used and communications should not be allowed to fall back on insecure or unencrypted protocols.
