What does the acronym SSL stand for in web security?

The acronym SSL stands for Secure Sockets Layer, which is a foundational technology in web security. SSL is a protocol that provides a secure channel between two machines operating over the internet or an internal network. It ensures that the data transmitted between a user's browser and a web server remains encrypted and secure from interception or tampering. This is particularly important for protecting sensitive information, such as personal details and payment information, while it is being transmitted.

SSL operates within a model of cryptographic security, utilizing certificates to establish the authenticity of websites and creating a secure connection through encryption. While the technology has evolved over the years, with newer protocols like TLS (Transport Layer Security) now being more widely used, the term SSL is still commonly referenced in discussions about secure communications on the web. Understanding SSL is crucial for comprehending how data is secured online and the mechanisms that protect users and their information during online transactions.
