iOS Security Features
Apple designs iOS security based on the principle that "privacy is a fundamental human right." By adopting a closed ecosystem, they achieve consistent security measures from hardware to software.
Closed Ecosystem
Apple's management of all hardware and software minimizes security holes. Unified quality control maintains consistent security levels.
Strict App Review
Rigorous App Store review process prevents malware and malicious app infiltration. Combination of human and AI review ensures high safety.
Hardware Encryption
Dedicated encryption processing by Secure Enclave chip. Protects biometric data and encryption keys in physically separated areas from software attacks.
Regular Updates
Rapid security updates simultaneously delivered to all iOS devices. Quick response to discovered vulnerabilities protects users.
Advanced Security of Face ID / Touch ID
Biometric data is processed within Secure Enclave and never sent to Apple servers. Face ID achieves 1 in 1,000,000 false acceptance rate, Touch ID 1 in 50,000, providing higher security than traditional passcodes.
Android Security Features
Google strengthens security while leveraging open source benefits under the "Android for Everyone" principle. Through cooperation with diverse device manufacturers, they provide security features to a wide range of users.
Open Source Benefits
Code review by developers worldwide enables early vulnerability discovery. Transparent development process achieves continuous security improvement.
Google Play Protect
Real-time app scanning using machine learning. Continuous monitoring before and after installation protects devices from malware and harmful apps.
Device Diversity
Security features available across various price points and specifications. Provides wide range of choices from entry models to flagships.
High Customizability
Security settings adaptable to enterprise and individual needs. Flexible permission management enables security optimized for usage environment.
Android Enterprise Corporate Security
Provides enterprise-specific security features. Comprehensive support for business environment needs including work profile separation, centralized app management, and remote wipe functionality.

Common Information Leak Risks
Whether choosing iOS or Android, both provide high OS-level security, but common information leak risks exist depending on user behavior and device management methods.
Data Recovery from Used Devices
Factory reset alone doesn't completely erase data, potentially allowing recovery with specialized tools.
- • Photo and video recovery
- • Contact information leaks
- • App usage history
Loss/Theft Risks
Information leak risks when devices are physically obtained are common to both OSes.
- • Passcode analysis attempts
- • SIM card misuse
- • Two-factor authentication bypass
Malicious App Installation
Risks from installing apps outside official stores or disguised apps.
- • Unauthorized personal information collection
- • Background communication
- • Permission abuse
Public Wi-Fi Dangers
Communication interception risks on unencrypted public Wi-Fi are similar for both OSes.
- • Communication content eavesdropping
- • Fake access points
- • Man-in-the-middle attacks
Importance of Secure Data Erasure
Regardless of iOS or Android OS usage, secure data erasure is necessary when selling, transferring, or disposing of devices. Standard factory reset functions alone don't guarantee complete data erasure.
Data Erasure Process
1. Backup
Pre-save necessary data
2. Account Removal
Sign out from various services
3. Specialized Tool Erasure
Complete erasure with MASAMUNE Erasure
4. Certificate Issuance
Obtain erasure completion certificate
MASAMUNE Erasure Dual OS Support
MASAMUNE Erasure is a specialized data erasure tool supporting both iOS and Android devices. Understanding each OS's characteristics, it applies optimal erasure algorithms to achieve secure data erasure.
- • iOS: Complete encryption key deletion and Secure Enclave support
- • Android: Erasure supporting diverse storage formats
- • Both OS: International standard-compliant erasure certificate issuance
Enterprise Selection Criteria
