Hard disk drive: a data storage device used for storing and retrieving digital information using rapidly rotating disks (platters) coated with magnetic material. These terms are:īoot loader: a small program (along with a small amount of needed data) stored in read-only memory (ROM) which accesses the nonvolatile device or devices from which the operating system programs and data can be loaded into RAM.

Not only does TrueCrypt make it simple to implement data-at-rest encryption, it’s free and easy to obtain.īefore you start to use TrueCrypt, you should be familiar with several terms which you will encounter when you install and configure it. As a result, your files will be safe from prying eyes if physical security measures of your drives are compromised (e.g., if your devices are ever stolen or seized).

TrueCrypt and similar tools obscure your files by converting them into unreadable code which, for all intents and purposes, is undecipherable without the required key. Since most of us have files which we do not wish to share with anybody or with only a select few individuals, it is recommended to lock down your computer drives with a solution like TrueCrypt. If access to the files on these devices is not restricted by encryption, then the intruder can easily view them. If an unauthorized user obtains physical access to your PC, laptop, smart phone, or USB flash drive, what then? A popular IT security maxim is: If a bad guy has unrestricted physical access to your data, it’s not your data anymore – he owns it. While technologies such as Tor and SSL/TLS protect the confidentiality of your data as it passes through computer networks (especially the Internet), they do not offer protection of the files you have stored, such as on internal and external hard drives. This article will explain how TrueCrypt works and how you can utilize it on the two most popular operating systems, Microsoft Windows and Linux. Now we will look at TrueCrypt, perhaps the most popular solution for encrypting data at rest. This blog has already covered SSH, RetroShare, and the Tor network as options for securing data in transit. Help is not far off: one of the most effective ways to foil surveillance is by using encryption to make your data unreadable by other parties.ĭata can be encrypted in two states – when it is in transmission through a communications network, or when it is at rest (i.e., stored on some sort of storage medium, such as a computer hard drive like the internal drive of your PC or an external USB flash drive). More and more Internet users are looking for solutions to keep their files, emails, and Web searches private. The home page of the next incarnation of TrueCrypt is TrueCrypt.ch.Īfter numerous revelations this year of the National Security Agency’s ( NSA) frightening capabilities of mass spying on phone calls and Internet traffic (see, for example, PRISM), there has been a renewed interest in online privacy and the securing of our electronic data communications, such as Web and email activity. Update: the TrueCrypt project unexpectedly shut down on.
