Which protocol is commonly associated with secure data in transit?

HTTPS, or Hypertext Transfer Protocol Secure, is commonly associated with secure data in transit because it establishes a secure communication channel over the internet. HTTPS encrypts the data exchanged between a user's web browser and a web server, which prevents eavesdropping, tampering, and man-in-the-middle attacks. This encryption is achieved using protocols such as SSL (Secure Sockets Layer) or TLS (Transport Layer Security).

Through this secure connection, sensitive information such as login credentials, personal data, and payment details can be transmitted safely, making HTTPS essential for protecting user privacy and data integrity online. Websites that handle sensitive information, such as online banking or e-commerce platforms, implement HTTPS to ensure their users' data is protected during transmission, providing a crucial layer of security in web communications.
