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

In the context of network security, SSL stands for Secure Sockets Layer. It is a protocol used to secure communication over a computer network. SSL provides a secure channel between two machines operating over the internet or an internal network, ensuring that the data being transmitted remains private and integral. This is achieved through the use of encryption, which protects the data from eavesdropping and tampering by unauthorized parties.

SSL is commonly utilized in web browsing, email, instant messaging, and other data transfers. A primary goal of SSL is to authenticate the server to the client and, optionally, the client to the server, establishing a secure connection that both parties can trust. This has led to SSL becoming a foundational technology for secure internet communications, which is essential for protecting sensitive information like personal data and financial transactions.

The other options do not accurately describe SSL. "System Standards Layer," "Secure Security Layer," and "Standard Sockets Layer" do not correspond to any recognized protocols or standards in network security, making them incorrect.
