Transport Layer Security (TLS), the successor of the now-deprecated Secure Sockets Layer (SSL), is a cryptographic protocol designed to provide communications security over a computer network.

  • It’s Dangerous to Use Outdated TLS Security Protocols
  • TLS 1.0 was first defined in RFC 2246 in January 1999 as an upgrade of SSL Version 3.0, and written by Christopher Allen and Tim Dierks of Consensus Development.
  • In October 2018, AppleGoogleMicrosoft, and Mozilla jointly announced they would deprecate TLS 1.0 and 1.1 in March 2020.
  • You must disable support for SSLv2, SSLv3, and TLS 1.0 because they are outdated and vulnerable
  • You should disable TLS 1.1 if you can because there are known security vulnerabilities such as vulnerable to BEAST and FREAK
  • You should enable TLS  1.2 and 1.3 as these are the current and secure versions
