Meaning of ‘TLS’

Transport Layer Security, commonly referred to as TLS, is a security protocol used in IT networks to protect data from unauthorized access and ensure its integrity. It is an encryption protocol developed by the Internet Engineering Task Force (IETF) and is used in conjunction with other protocols such as SSL/TLS (Secure Sockets Layer/Transport Layer Security). TLS is designed to provide authentication, confidentiality, and data integrity for communication between two or more parties over a computer network.

The purpose of TLS is to secure communications between two or more parties by providing authentication, confidentiality and integrity of data. This means that when data is sent over the Internet, it will remain private and can only be accessed by the intended recipient. Additionally, TLS ensures that the data remains unaltered during transmission by using cryptographic techniques such as digital signatures and message authentication codes.

To understand how TLS works, we must first look at the different layers of security it uses. The Transport Layer Security protocol consists of four layers: the Record Protocol layer; Handshake Protocol layer; Alert Protocol layer; and Change Cipher Specification layer. Each layer provides a specific set of features to ensure data privacy, reliability and authenticity.

At the Record Protocol layer, TLS encrypts application-level messages such as emails or webpages before they are sent over a network connection. This helps to prevent eavesdropping on transmissions across the Internet or an internal network. The Handshake Protocol layer allows two applications to authenticate each other before exchanging any sensitive information. This prevents malicious attackers from impersonating legitimate users or services on a network connection. The Alert Protocol layer monitors encrypted connections for any abnormal activity that could indicate tampering with messages in transit, while Change Cipher Specification allows for encryption keys to be updated periodically for better security.

Overall, Transport Layer Security plays an important role in securing communications over computer networks by ensuring authentication and confidentiality of data between two or more parties. It also provides additional protection against malicious attackers who may attempt to gain access to sensitive information through man-in-the-middle attacks or other forms of online fraudulence. By using TLS along with other protocols such as SSL/TLS (Secure Sockets Layer/Transport Layer Security), organizations can help ensure their networks are free from unauthorized access while maintaining strong privacy standards throughout their entire infrastructure
