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

SSL stands for Secure Sockets Layer, and it plays a crucial role in internet security by ensuring that data transmitted between a user's browser and a web server is encrypted and secure. This encryption helps protect sensitive information, such as personal details, payment information, and login credentials, from interception by unauthorized parties during transmission.

When a website uses SSL, users can see visual indicators in their browser, such as a padlock icon in the address bar, which assures them that their connection is secure. This trust factor is essential for users when engaging in online transactions or sharing personal information.

The ability to secure data in transit is vital for maintaining confidentiality and integrity, which are core components of cybersecurity. Without SSL, data sent over the internet could be easily captured and altered, leading to potential threats such as identity theft or financial fraud. Thus, SSL is fundamental in establishing secure online communications and protecting user data.
