Transport Layer Security - TLS
Transport Layer Security, TLS, is an industry-standard encryption protocol created to offer secure end-to-end web-based communications between devices. Since it provides a higher level of security TLS has replaced the formerly used Secure Socket Layer or SSL protocol.
Today, most of us would not use a website that does not include the padlock icon usually found at the top left side corner of the web page or one that does not begin with HTTPS://. HTTPS is the implementation of TLS encryption on top of the HTTP protocol. These items provide us with the confidence that our connection to the server and our transaction are protected from hackers, eavesdroppers, and other cybercriminals.
The Three Main Components of the TLS protocol performs the following functions:
Encryption: blocking the visibility of data being transferred between the client and the server to prevent eavesdropping.
Authentication: validating and ensuring the parties exchanging information are who they say they are.
Integrity: verifying the accuracy of the data to ensure it was not tampered with or altered.
