What does SSL stand for, and why is it important?

The correct response identifies SSL as Secure Sockets Layer, which is a critical technology used to establish an encrypted link between a web server and a browser. This encrypted connection ensures that all data exchanged between the user’s browser and the server remains private and integral. This is essential for protecting sensitive information, such as credit card numbers, personal details, and login credentials, from being intercepted by malicious actors during transmission.

SSL's importance extends beyond just encryption; it also plays a vital role in establishing trust with users. When a website is secured with SSL, users can see indicators such as a padlock icon in the address bar, reassuring them that their data is being handled securely. In today's digital environment, where data breaches are increasingly common, SSL is fundamental for maintaining the confidentiality and integrity of online communications, making it a cornerstone of web security practices.
