To protect data during internet transmission, various technologies are employed, with TLS (Transport Layer Security) being one of the most widely used. It establishes a secure channel between two endpoints, ensuring that data transferred remains confidential and protected from interception. This process involves encryption, authentication of the parties involved, and message integrity checks. By utilizing TLS, organizations can safeguard sensitive information, such as credit card details and login credentials, mitigating the risks associated with cyber attacks and data breaches.
