Title
The operating system must enforce requirements for remote connections to the information system. (Cat II impact)
Discussion
The Screen Sharing feature allows remote users to view or control the desktop of the current user. A malicious user can take advantage of Screen Sharing to gain full access to the system remotely, either with stolen credentials or by guessing the username and password. Disabling Screen Sharing mitigates this risk.

Fix Text
