Description:
Hyper Text Transfer Protocol Secure (HTTPS) is a secure version of the Hyper Text Transfer Protocol (http). HTTPS allows secure ecommerce transactions, such as online banking.
Web browsers such as Internet Explorer and Firefox display a padlock icon to indicate that the website is secure, as it also displays "https://" in the address bar.
When a user connects to a website via HTTPS, the website encrypts the session with a digital certificate. A user can tell if they are connected to a secure website if the website URL begins with "https://" instead of "http://".
Complete Definition:
https is a URI scheme which is syntactically identical to the http: scheme normally used for accessing resources using HTTP. Using an https: URL indicates that HTTP is to be used, but with a different default port (443) and an additional encryption/authentication layer between HTTP and TCP. This system was invented by Netscape Communications Corporation to provide authentication and encrypted communication and is widely used on the World Wide Web for security-sensitive communication, such as payment transactions, and corporate logons.
Enabling HTTPs Access on Cisco a Router:
You can configure and monitor your router using an encrypted browser interface.
To enable secure HTTP (HTTPS) access to a router, use the "ip http secure-server" command:
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#ip http secure-server
Router(config)#end
By default, the secure HTTP server uses port 443. You can also change the secure server port, using the following command:
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#ip http secure-port 8080
Router(config)#end
To view the secure HTTP configuration status, use the "show ip http server secure status" command:
Router#show ip http server secure status
