3. App Store Review Process:

Apple employs a system that scrutinizes all the apps submitted to the App Store before they are released for public use. This review process assists in making sure that apps do not contain codes that are not acceptable by Apple standards.

4. Automatic Updates:

Apple usually releases iOS updates to fix known security problems and enhance the system’s overall security. iOS devices have been programmed to download and install these updates so that the users of the devices are protected from known security threats.

Security Model of Android

The Android security model is a set of principles that enforce security to protect the user and their data and the integrity of the applications and devices. It is built on several fundamental principles and mechanisms:

1. App Sandbox:

Android uses the sandbox model, where every application runs in a separate environment that is not connected to the system or other applications. This helps prevent unauthorized access to sensitive data, improving the overall security system of the application.

2. Authentication:

Android provides several authentication mechanisms, such as passwords, pins, patterns, and biometrics. These mechanisms assist in verifying the user’s identity and guarantee that only authenticated users will have access to the device and its data, which helps boost the overall security level of the device.

3. Biometrics:

Biometric authentication is supported in Android devices through fingerprint scanning, facial recognition, and iris scanning. They allow users to quickly and securely verify their identities to access and protect devices and personal information.

4. Encryption:

Android uses various encryption mechanisms to protect data in devices. This involves encrypting the entire device and the data in files and applications. Encryption helps users protect their privacy and security even when they might have lost or stolen the devices.
