The acronym SSL stands for Secure Sockets Layer, which is crucial for establishing a secure and encrypted connection between a user’s browser and a web server. SSL helps protect sensitive data during transmission, mitigating risks such as data breaches and man-in-the-middle attacks. Although SSL has been largely replaced by Transport Layer Security (TLS) in modern protocols, many still refer to them collectively as SSL. Its importance lies in safeguarding online transactions and promoting user trust in e-commerce and data exchange.
