Which measure is crucial to preventing data breaches in mobile devices?

• A. Regular OS updates
• B. Implementing strong passwords
• C. Full-device encryption
• D. Limiting app installations

Answer: (C)

Full-device encryption is a crucial measure for preventing data breaches in mobile devices because it helps protect the data stored on the device from unauthorized access. When a device is fully encrypted, the information it contains is transformed into a format that cannot be easily understood without the appropriate decryption keys. This means that if the mobile device is lost, stolen, or accessed by an unauthorized user, the data remains secure and inaccessible without the proper credentials or keys. While other measures such as regular operating system updates, implementing strong passwords, and limiting app installations contribute to overall security, they primarily focus on defense against malware, unauthorized access, and minimizing vulnerabilities rather than directly securing the data itself. With full-device encryption, even if an attacker bypasses other security measures, the data remains protected, making it one of the most effective strategies to safeguard sensitive information on mobile devices.
