Apple iOS/iPadOS 16 must be configured to disable Auto Unlock of the iPhone by an Apple Watch.
An XCCDF Rule
Description
<VulnDiscussion>Auto Unlock allows an Apple Watch to automatically unlock an iPhone or Mac when in close proximity (not available for iPad). This feature allows the iPhone/Mac to be unlocked without the user entering the device passcode, which may lead to unauthorized users access to the iPhone/Mac and sensitive DoD data. This control is not applicable if the authorizing official (AO) has approved the use of Apple Watches.
