The TLS protocol aims primarily to provide privacy and data integrity between two or more communicating computer applications. It runs in the application layer of the Internet and is itself composed of two layers: the TLS record and the TLS handshake protocols.

What layer protocol is TLS?

The TLS (and SSL) protocols are located between the application protocol layer and the TCP/IP layer, where they can secure and send application data to the transport layer. Because the protocols work between the application layer and the transport layer, TLS and SSL can support multiple application layer protocols.

What network layer is TLS?

TLS belongs to the Session Layer. The Network layer deals with addressing and routing; it can be ruled out. The Transport layer ensures end-to-end transmission by flow control and error detection and recovery.
