  HTTPS stands for HTTP over SSL or HTTP Secure. It is used for secure access to websites. Port 80 web sessions are HTTP (HyperText Transfer Protocol) sessions which offers no security. Port 443 web sessions use HTTPS. HTTPS uses SSL or TLS to encrypt the HTTP traffic. HTTPS provides authentication of the website and associated web server that you are communicating with, which protects against man-in-the-middle attacks. Additionally, it provides bidirectional encryption of communications between a client and server, which protects against eavesdropping and tampering with and/or forging the contents of the communication.
