Hypertext Transfer Protocol Secure (HTTPS): HTTPS provides a more secure version of the standard HTTP protocol by using the TLS or SSL encryption standard. This combination of protocols ensures that all data transmitted between the server and the web browser is encrypted and protected against eavesdropping or data packet sniffing. The same principle applies to POPS, SMTPS, and IMAPS to create secure versions of the POP, SMTP, and IMAP protocols previously described.
