\nHTTPS (Hypertext Transfer Protocol Secure) is the protocol used for secure communication over computer networks, particularly for accessing websites. It combines the standard HTTP protocol with an encryption layer, typically Transport Layer Security (TLS) or its predecessor Secure Sockets Layer (SSL). This encryption ensures that data transmitted between the user’s browser and the server is protected from eavesdropping and tampering.
\n– HTTP is the standard, non-secure web protocol.
\n– DHCP is used for assigning IP addresses.
\n– SMTP is used for sending email.
\n<\/section>\n
\n– HTTPS adds a security layer (TLS\/SSL) to HTTP.
\n– It encrypts data exchanged between client and server, ensuring confidentiality and integrity.
\n<\/section>\n
\nWhile SMTP can be secured using extensions like STARTTLS or SMTPS, the base SMTP protocol itself is not secure. Similarly, other protocols have secure variants (e.g., SFTP for FTP, SSH for Telnet). HTTPS is the standard secure version for web communication.
