What does the acronym SSL signify in internet security?

The acronym SSL stands for Secure Socket Layer. It is a standard technology that establishes an encrypted link between a web server and a browser, ensuring that all data transmitted between the two remains private and secure. SSL is fundamental for protecting sensitive information such as login credentials, credit card numbers, and personal data while in transit over the internet.

SSL has largely been succeeded by TLS (Transport Layer Security), which offers improved security and is commonly referred to as the modern version of SSL. However, the term SSL is still widely used to refer to both SSL and TLS protocols. Understanding the significance of SSL in the context of internet security is crucial for recognizing how it protects users and maintains the confidentiality and integrity of data during online communications.
