What is SSL and what does it provide for web security?

SSL stands for Secure Sockets Layer, and it is a protocol that establishes a secure, encrypted link between a web server and a browser. This encryption plays a crucial role in web security by ensuring that any data transmitted between the server and the browser remains private and is not intercepted by unauthorized parties.

When SSL is implemented on a website, it protects sensitive information such as login credentials, payment details, and personal data from eavesdropping and tampering. By encrypting the data during transmission, SSL helps establish a secure communication channel, which is vital for maintaining the confidentiality and integrity of the information being exchanged.

In summary, SSL provides a foundational level of security for web transactions, playing a crucial role in building trust and ensuring the safe handling of sensitive data over the internet.
