What is a common function of the Secure Sockets Layer (SSL)?

  1. Facilitating file transfers over a network.

  2. Providing email encryption.

  3. Ensuring secure communication over network connections.

  4. Managing network devices.

The correct answer is: Ensuring secure communication over network connections.

The primary function of Secure Sockets Layer (SSL) is to ensure secure communication over network connections. SSL establishes an encrypted link between a web server and a browser, which safeguards the data being transmitted. This is crucial for protecting sensitive information, such as credit card details, personal data, and confidential communications, from being intercepted by unauthorized parties during transmission over the internet. By employing encryption protocols, SSL not only helps in ensuring the integrity and confidentiality of data but also authenticates the identity of the communicating parties, providing a secure environment for data exchange. This makes SSL integral to establishing trust between users and online services, particularly in e-commerce and online banking transactions.
