John has performed a scan of the web server with NMAP but did not gather enough information to accurately identify which operating system is running on the remote host. How could you use a web server to help in identifying the OS that is being used?
A.
Telnet to an Open port and grab the banner
B.
Connect to the web server with an FTP client
C.
Connect to the web server with a browser and look at the web page
D.
Telnet to port 8080 on the web server and look at the default page code
Explanation:
Most Web servers politely identify themselves and the OS to anyone who asks.
