Boot protection and authentication

Boot Protection

A common misconception is that boot protection and the BIOS password scheme offered by computer manufacturers offer the same protection as encryption. This is not the case.

Boot protection prevents the operating system from being launched by an unauthorized person. A standard BIOS protection seems to do the same thing, but unfortunately, most BIOS level protection schemes are fatally weak and cannot be tightly linked with the crucial encryption.

Data Must be Encrypted

While controlling access to the computer is important, this does not by itself protect the data stored on the disk. For example, a simple boot floppy disk could be used to bypass boot protection. Alternatively, removing the drive and placing it in another computer will make the files accessible if they are not encrypted. This is why information on used hard drives, bought over the internet, is free to examine by the buyer.

To secure stored data, it must be encrypted. Once encrypted with full disk encryption, the files will be inaccessible to any unauthorized person and immune to the widely available password cracking tools.
