- Auto-lock after inactivity.
Enforce biometric authentication (Face ID or Touch ID).

4. Disable Unapproved Features¶

Why: Limits attack vectors.
How (via MDM):
Disable:
- AirDrop
- iCloud Backup if sensitive data should remain on-premises.
- Personal Hotspot
- Screen Recording.

5. Enforce Network Security Settings¶

Why: Protects data during transmission.
How (via MDM):
