Which port does hypertext transfer protocol secure (HTTPS) use?

• A. 80
• B. 443
• C. 21
• D. 110

Answer: (B)

Hypertext Transfer Protocol Secure (HTTPS) primarily operates over port 443. This port is designated for secure internet communications, utilizing Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL), to encrypt data transmitted between a web browser and a web server. The use of this port enhances security by protecting sensitive information against eavesdropping and tampering, which is vital for online transactions and secure data transmission. While port 80 is associated with standard Hypertext Transfer Protocol (HTTP) traffic, it does not provide the same level of security as HTTPS. Ports 21 and 110 are used for File Transfer Protocol (FTP) and Post Office Protocol (POP) respectively, neither of which relates to web traffic security. Understanding these port assignments is essential for network security and effective management of web resources.
