What does SSL stand for in the context of web security?

SSL stands for Secure Socket Layer, which is a protocol used to establish a secure, encrypted link between a web server and a browser. This ensures that any data transmitted between the two remains private and integral, preventing eavesdropping or tampering by unauthorized parties. SSL is critical for protecting sensitive information, like credit card details and personal data, when users interact with web applications, ensuring secure transactions over the internet.

The protocol has evolved over time, and while SSL itself is now considered outdated and has been succeeded by Transport Layer Security (TLS), the term SSL is still widely used to refer to these secure communication technologies. Understanding SSL is foundational in the realms of web security and data protection as it helps safeguard user information against cyber threats.
