SSL, or Secure Sockets Layer, is most commonly used to secure web traffic. This protocol ensures that the data transferred between a web server and a client's browser remains encrypted, providing confidentiality and integrity. When you visit a website that uses HTTPS, SSL is the underlying technology that protects the data being transmitted, such as login credentials, personal information, and payment details.

By establishing a secure encrypted connection, SSL prevents unauthorized access and eavesdropping during the transmission of data over the internet, which is crucial in maintaining user trust and safeguarding sensitive information.

The other scenarios mentioned do not align with the primary purpose of SSL. Data storage improvements focus more on efficiency and management rather than security. Monitoring network performance involves analyzing data flow and resource usage but does not directly involve encryption or securing communications. Similarly, backup solutions relate to the preservation of data and recovery strategies, rather than the protection of data in transit.
