Secure web browsing uses Hypertext Transfer Protocol Secure (HTTPS). By default, HTTPS uses TCP port 443 to encrypt communications and ensure secure transmission of data between the client and server. Port 80 is used for standard, unencrypted HTTP traffic. Port 53 is commonly reserved for DNS services and 23 for Telnet, which is not secure and not used for web browsing.
