Explanation:
Detailed explanation-1: -HTTPS over port 443 is used for the transmission of secured traffic, thus creating a secure communication channel between the client browser and the server it wants to connect to.
Detailed explanation-2: -What type of port scan results can you get from port scanning? Port scan results reveal the status of the network or server and can be described in one of three categories: open, closed, or filtered.
Detailed explanation-3: -Simplest way to do that is probably (on the server, in a cmd window) netstat-an | find “1443” and see what you get back. Second, if it’s a TCP connection you’re looking for, you may be able to telnet <hostname> 1443 and see if you get a connection.
