Set a Passcode

Users should configure the iPhone to require a passcode before it can be used. This can help make it more difficult for an unauthorized user to access any data on the device if it is lost or stolen.

Destroy Data if the Wrong Password Is Entered

Users should consider setting their phone to erase data stored on the device after an excessive number of passcode failures. CIS recommends it be set to erase after 10 failed access attempts.

Forgetting Wi-Fi Networks

A trusted but unauthenticated network can be spoofed and automatically joined if the phone isnt set to forget the network after it was last used.
