TLS stands for Transport Layer Security. It is a protocol that is used to establish a secure connection between two devices, such as a web server and a client (e.g., a web browser). TLS is designed to protect the privacy of communications over the internet by encrypting the data that is transmitted between devices. This encryption helps to ensure that the data cannot be intercepted or tampered with by any third party. TLS is often used in conjunction with other protocols, such as HTTP (Hypertext Transfer Protocol), to provide a secure connection for online transactions, such as online banking, online shopping, and other sensitive activities.
TLS is important because it helps to protect the privacy and security of communications over the internet. Without TLS, the data transmitted between devices could potentially be intercepted or tampered with by third parties, which could lead to a variety of security risks. For example, if sensitive information, such as passwords or financial information, is transmitted over the internet without being encrypted, it could be easily accessed by hackers or other malicious actors.
