What is a characteristic of iOS security?

Apple designs iOS so that users actively configure core security features through Settings - they enroll Face ID or Touch ID, set passcode complexity, grant or revoke per-app access to the camera, microphone, location, and contacts, and control data sharing options. This user-driven configuration model is a deliberate architectural choice that distinguishes iOS and gives end users significant influence over their device's security posture.

iOS enforces a more restrictive architecture than macOS through mandatory app sandboxing, enforced code signing, and App Store distribution requirements that macOS does not impose by default.

The Open Handset Alliance (OHA) is the industry group that backs Android, not iOS; Apple manages its own security disclosures and patches independently through its own Product Security process.

iOS does not categorically forbid mobile operator software; carrier apps are available through the App Store and operators can provision certain carrier-specific profiles and applications.
