What does SSL stand for in network security?

SSL stands for Secure Sockets Layer, which is a protocol for establishing a secure connection between a client and a server over the internet. It enables the encryption of data during transmission, ensuring that sensitive information such as passwords, credit card numbers, and personal data remain confidential and are protected from eavesdropping or tampering by malicious actors.

The SSL protocol works by using a combination of public key and symmetric key encryption, which allows for secure data exchange. It establishes a secure session through a handshake process, where the client and server authenticate each other and negotiate encryption parameters. This is fundamental to maintaining the integrity and security of data transmitted over insecure networks, such as the internet.

The other options do not accurately represent what SSL stands for or relate to an established networking security protocol. For example, Simple Security Layer and Structured Security Level do not exist as recognized protocols in the context of network security, while Secure Socket Logic does not pertain to any standard widely accepted in the industry. Understanding the significance of SSL is crucial for anyone working with network security, as it lays the foundation for secure communications online.
