Network - TLS

About

TLS is a cryptographic protocol and the successor to SSL, and is described in the RFC 2246 standard.

The protocol name was changed from SSL to TLS when it became a standard.

TLS is a protocol that helps provide privacy between communicating applications. When a server and client communicate, TLS ensures that no third party can overhear or tamper with any messages.

TLS is

It secures the traffic from the beginning of the connection. If you want to secure the traffic in the middle of a plain text connection, you should use StartTLS
