You work for a small city IT department and you are assistin

You work for a small city IT department and you are assisting a customer secure data on a Windows Vista laptop he is about to take on a business trip. You want to make sure that, if the laptop is stolen, the data will not be compromised. Which security measure do you use that works before the Windows operating system is even loaded and encrypts the entire volume?

A. BitLocker

B. EFS

C. Intrusion detection

D. TPM

Solution

Best Data security measure on Windows platform is to use bitlocker. TPM (Trusted platform module) is a chip installed on the motherbord itself and it support bitlocker encryption by partially saving the encryption key on TPM itself, which provides hardware authentication.

Windows EFS encryption technology is a older approach and the main shortcoming of it is that encryptionkey is saved on the drive itself, which needs encryption for data security purpose.
