Phrase: TLS heartbeat extension (later deprecated) | Statement: [TLS Working Group, responsibleFor, TLS heartbeat extension (later deprecated)]

Target entity: TLS heartbeat extension (later deprecated)
Context triple: [TLS Working Group, responsibleFor, TLS heartbeat extension (later deprecated)]

• C. TLS 1.1
  TLS 1.1 is an older version of the Transport Layer Security protocol that improved upon earlier SSL standards but has since been deprecated in favor of more secure versions like TLS 1.2 and 1.3.
• D. TLS 1.2 Finished message
  The TLS 1.2 Finished message is the protocol’s final handshake message that proves both parties share the same session keys and that the preceding handshake messages have not been tampered with.
• E. Server Name Indication extension
