Every few years we see that the new versions of SSL/TLS is released to address the security vulnerabilities (e.g., BEAST, POODLE, DROWN) and support the strongest and most secure cipher suites. The latest being TLS 1.3, which was just approved by the IETF (Internet Engineering Task Force). As a industry best practice, you should disable the old protocols which are vulnerable…
