The Best Solution for Securing Ann's Laptop During Travel

A.

The best solution in this scenario is A. Full disk encryption.

Full disk encryption (FDE) is a security feature that encrypts the entire hard drive of a device, making it impossible for anyone without the proper credentials to access the data stored on the device. FDE provides a layer of protection for Ann's data in the event her laptop falls into the wrong hands.

In this scenario, Ann frequently leaves her laptop unattended and physically unsecured in hotel rooms during travel, making it easy for competitors to obtain corporate secrets. By implementing FDE, Ann's data is protected even if her laptop is stolen or accessed without authorization. This solution requires no user training, as the encryption and decryption of the data are done automatically in the background.

Biometric authentication, eFuse-based solution, and two-factor authentication are not the best solutions in this scenario for several reasons:

• Biometric authentication requires user training and physical hardware to read biometric data such as fingerprints, iris scans, or facial recognition. It is also not foolproof and can be bypassed by advanced means.
• An eFuse-based solution is a hardware-based security feature that prevents unauthorized access to the device by detecting tampering attempts. However, this solution also requires user training and is not relevant to the scenario described.
• Two-factor authentication adds an additional layer of security by requiring a secondary form of identification in addition to a password. However, it does not address the issue of physical security and unattended laptops in hotel rooms.

In conclusion, full disk encryption is the best solution in this scenario as it provides automatic, transparent data protection without requiring user training.
