The macOS system must disable iCloud Keychain synchronization.


Overview

Finding ID Version Rule ID IA Controls Severity
V-259501 APPL-14-002040 SV-259501r958478_rule Medium
Description
The macOS system's ability to automatically synchronize a user's passwords to their iCloud account must be disabled. Apple's iCloud service does not provide an organization with enough control over the storage and access of data and, therefore, password management and synchronization must be controlled by an organization approved service.
