What is SSL used for?

  1. Encrypt web traffic

  2. Speed up web traffic

  3. Monitor web traffic

  4. Decrypt web traffic

The correct answer is: Encrypt web traffic

SSL stands for Secure Socket Layer and is used to encrypt web traffic, providing a secure connection between a web server and a web browser. Option B is incorrect because while SSL does improve the security and reliability of data transfers, its main purpose is not to speed up web traffic. Option C is incorrect because while SSL may log data to track potentially malicious activity, it is not primarily used for monitoring web traffic. Option D is incorrect because SSL does not decrypt traffic, but rather it encrypts it, making it more secure.
