A security administrator has deployed all laptops with Self Encrypting Drives (SED) and enforces key encryption. Which of the following represents the greatest threat to maintaining data confidentiality with these devices?
Correct Answer: D
Explanation/Reference: Explanation: Hardware-based encryption when built into the drive is transparent to the user. The drive except for bootup authentication operates just like any drive with no degradation in performance. When the computer is started up, the user is prompted to enter a password to allow the system to boot and allow access to the encrypted drive. When a laptop is placed into sleep mode (also known as standby mode), the computer is placed into a low power mode. In sleep mode, the computer is not fully shut down. The screen is turned off, the hard disks are turned off and the CPU is throttled down to its lowest power state. However, the computer state is maintained in memory (RAM). Most computers can be 'woken' from sleep mode by pressing any key on the keyboard or pressing the power button. The computer can be configured to require a password on wake up, but if a password is not required, the computer will wake up and be logged in as it was at the time of going into sleep mode. This would enable full access to the data stored on the disks.
