Ensure Guest Account Is Disabled

高レベル 1自動macos

説明

The guest account allows users access to the system without having to create an account or password. Guest users are unable to make setting changes and cannot remotely login to the system. All files, caches, and passwords created by the guest user are deleted upon logging out. Disabling the guest account mitigates the risk of an untrusted user doing basic reconnaissance and possibly using privilege escalation attacks to take control of the system.
