Sure, you can protect your computer’s sensitive data by using a firewall, anti-virus/malware programs, etc. to help keep hackers out, but what if your laptop or computer is stolen? 
If you’re a Windows user, you may feel a little better thinking that your Windows account password will keep the thief from sifting through your personal information stored on your hard drive. While it’s understandable to feel that way, you might want to think again.
There are many programs out there that make it very easy to hack one’s Windows account password. While most of these programs are designed for legitimate purposes, they often fall into the wrong hands allowing personal information to become discovered and distributed very easily.
Our suggestion to protect against this form of data theft? Disk encryption — including your OS — by using a secure algorithm. Which leads us to this handy little program called TrueCrypt. Not only is TrueCrypt free, but it allows you to encrypt your entire hard drive(s) very quickly and easily thanks to this tutorial aimed at beginners.
Choosing the right level of disk encryption is optional depending on your needs obviously. But it is far more secure than a simple Windows account password and will keep the common thief from harvesting your private data. To better understand encryption algorithms so you can choose the right one for you, see their documentation located here.
It should be said that it is always a good idea to backup your data to an external source prior to encrypting your drives in case anything goes wrong during the encryption process (we’ll follow up with a later post on our favorite backup/imaging methods).
TrueCrypt not only works on Windows, but Mac OS X and Linux as well. If you’re ready to give TrueCrypt a shot, you can download the latest version here.
