Under HTTP 1.0, connections should always be closed by the server after sending the response. [1]Since at least late 1995, [2] developers of popular products (browsers, web servers, etc.) using HTTP/1.0, started to add an unofficial extension (to the protocol) named "keep-alive" in order to allow the reuse of a connection for multiple requests/responses.
It was introduced into the software in 2012 and publicly disclosed in April 2014. Heartbleed could be exploited regardless of whether the vulnerable OpenSSL instance is running as a TLS server or client. It resulted from improper input validation (due to a missing bounds check) in the implementation of the TLS heartbeat extension. [5]

Server Name Indication (SNI) is an extension to the Transport Layer Security (TLS) computer networking protocol by which a client indicates which hostname it is attempting to connect to at the start of the handshaking process. [1]
Delegated credential is a short-lived TLS certificate used to improve security by faster recovery from private key leakage, without increasing the latency of the TLS handshake. It is currently an IETF Internet Draft , [ 1 ] and has been in use by Cloudflare [ 2 ] and Facebook , [ 3 ] with browser support by Firefox .
Incoming HTTPS traffic gets decrypted and forwarded to a web service in the private network. A TLS termination proxy (or SSL termination proxy, [1] or SSL offloading [2]) is a proxy server that acts as an intermediary point between client and server applications, and is used to terminate and/or establish TLS (or DTLS) tunnels by decrypting and/or encrypting communications.
A workaround for SSL 3.0 and TLS 1.0, roughly equivalent to random IVs from TLS 1.1, was widely adopted by many implementations in late 2011. [30] In 2014, the POODLE vulnerability of SSL 3.0 was discovered, which takes advantage of the known vulnerabilities in CBC, and an insecure fallback negotiation used in browsers.
This selection process occurs during the TLS Handshake Protocol. TLS 1.3 includes a TLS Handshake Protocol that differs compared to past and the current version of TLS/SSL. After coordinating which cipher suite to use, the server and the client still have the ability to change the coordinated ciphers by using the ChangeCipherSpec protocol in ...
