Which cybersecurity measure can help prevent unauthorized data access from lost mobile devices?

• A. Regular malware scans
• B. File encryption and strong passphrase security
• C. Potential remote access solutions
• D. Increase physical security measures

Answer: (B)

File encryption and strong passphrase security are essential cybersecurity measures for preventing unauthorized data access from lost mobile devices. When sensitive data on a mobile device is encrypted, it becomes unreadable without the correct decryption key. This means that even if an unauthorized individual obtains the device, they will not be able to access the data unless they also have the strong passphrase needed to decrypt it. Implementing robust passphrase security further strengthens this defense. A strong passphrase is typically longer and more complex than a standard password, making it significantly harder for attackers to guess or crack using brute-force methods. By combining these two measures, organizations can greatly reduce the risk of data breaches resulting from lost or stolen devices. While options like regular malware scans, remote access solutions, and increased physical security measures play important roles in a comprehensive security strategy, they do not specifically address the issue of protecting data on lost mobile devices as effectively as encryption and strong passphrases do. Regular malware scans primarily focus on detecting and mitigating active threats on a device rather than safeguarding data directly. Similarly, remote access solutions can aid in data management but would not prevent data access in the event the device is lost. Increased physical security measures can help reduce the likelihood of device loss but do not provide protection
