Transport Layer Security (TLS)

Transport layer security (TLS) is a protocol that provides communication security between client/server applications that communicate with each other over the Internet. It enables privacy, integrity and protection for the data that's transmitted between different nodes on the Internet. TLS is a successor to the secure socket layer (SSL) protocol.

TLS primarily enables secure Web browsing, applications access, data transfer and most Internet-based communication. It prevents the transmitted/transported data from being eavesdropped or tampered. TLS is used to secure Web browsers, Web servers, VPNs, database servers and more. TLS protocol consists of two different layers of sub-protocols:

• TLS Handshake Protocol: Enables the client and server to authenticate each other and select a encryption algorithm prior to sending the data
• TLS Record Protocol: It works on top of the standard TCP protocol to ensure that the created connection is secure and reliable. It also provides data encapsulation and data encryption services.
