Disabling HTTP Communication
HTTP is used for communications over the network, such as when you access the machine via the Remote UI. If you
are using a USB connection or are otherwise not using HTTP, you can disable HTTP to block malicious third-party
intrusions via the unused HTTP port.
Disabling HTTP disables some of the network capabilities, such as the Remote UI, WSD printing, and printing
