What does SSL provide in the context of network security?

SSL, or Secure Sockets Layer, is primarily known for providing secure web browsing over HTTPS. It establishes an encrypted link between a web server and a client (like a web browser), ensuring that all data exchanged remains private and integral. This encryption protects sensitive information, such as login credentials, credit card numbers, and personal details, from being intercepted by malicious actors.

When a browser connects to a server using HTTPS, SSL facilitates a handshake that verifies the identity of the server and ensures that the data transmitted is encrypted. This process not only secures the transmission but also builds trust with users who see visual cues, like a padlock icon in the browser address bar, indicating that their connection is secured.

While data compression, network address translation (NAT), and file transfer protocols serve important purposes in networking, they do not directly relate to the functions and benefits provided by SSL in the context of secure communications over the web.
