Ensure Guest Access to Shared Folders Is Disabled

BaixaNível 1Revisão manualmacos

Descrição

Allowing guests to connect to shared folders enables users to access selected shared folders and their contents from different computers on a network. Not allowing guests to connect to shared folders mitigates the risk of an untrusted user doing basic reconnaissance and possibly using privilege escalation attacks to take control of the system.
