Prevent unauthorized access by blocking guest login sessions. This guide applies to Mac computers ### About the Don't Allow Guest User to Log In Parameter This parameter disables the Guest user account on Mac computers, which is considered a security vulnerability because it grants access without login credentials. ### How It Works When enabled, Iru Endpoint will ensure the Guest user feature is disabled. During each check-in, Iru Endpoint will verify and adjust settings to the disabled state should they change. By default, macOS allows a Guest user account that grants access to the general macOS system and apps without login credentials. The Guest user is considered a security vulnerability because it does not have a password. It's recommended that the Guest user account be disabled on all macOS systems unless there is a demonstrated need. ### Enabling this Parameter When enabled, Iru Endpoint will ensure the Guest user feature is disabled. During each check-in, Iru Endpoint will verify and adjust settings to the disabled state should they change. ### Disabling this Parameter Disabling this parameter stops Iru Endpoint from managing the Guest user feature during each check-in. The feature will remain in its current state until a user manually changes it.
