Carolyn runs a vulnerability scan of a network device and discovers that the device is running services on TCP ports 22 and 443. What services has she most likely discovered?

A network device running SSH on port 22 and a web server on TCP port 443 is a very typical discovery when running a vulnerability scan. Without any demonstrated issues, Carolyn should simply note that she saw those services. Telnet runs on port 21, an unencrypted web server will run on TCP 80 in most cases, and Windows file shares use a variety of ports, including TCP ports 135–139 and 445.
