You work for a small city IT department, and you are discussing methods of securing laptops, desktops, and servers with another technician. Of the following methods, which one do you say is used by disk encryption applications to protect the keys used to encrypt a computer’s hard drives?

A. Drive lock

B. BIOS password

C. Chassis intrusion detection

D. TPM

Solution

a) Drive Lock

Some hard disk drives allow us to give password. If any other person wants to access our drive then he must have to enter the password given by us to access it. This password is stored on the drive. So this password will work if it is moved to another computer.

It is vital because it protects the entire drive, including all the data.

d) TPM (Trusted Platform Module)

Now a day’s computers have a chip on the motherboard called the Trusted Platform Module chip. This chip holds the BitLocker encryption key.

If someone installs the hard drive another computer, he cannot access it, because BitLocker has encrypted all contents on the drive.

It is vital because the drive cannot be used in another computer.
