It’s all too easy to neglect data security, especially for a small business. While bigger organizations have IT departments, service contracts, and enterprise hardware, smaller companies frequently rely on consumer software, which lacks the same sort of always-on security functionality.
But that doesnt mean that your data is unimportant, or that it has to be at risk.
Encryption is a great way to keep valuable data safewhether youre transmitting it over the Internet, backing it up on a server, or just carrying it through airport security on your laptop. Encrypting your data makes it completely unreadable to anyone but you or its intended recipient. Best of all, much of the software used in offices and on personal computers already has encryption functionality built in. You just need to know where to find it. In this article, Ill show you where and how.
Any discussion about encryption needs to start with a different topic: password strength. Most forms of encryption require you to set a password, which allows you to encrypt the file and to decrypt it later on when you want to view it again. If you use a weak password, a hacker can break the encryption and access the filedefeating the purpose of encryption.
A strong password should be at least 10 characters, though 12 is better. It should include a mix of uppercase and lowercase letters, as well as numbers and symbols. If you find letters-only easier to remember, such a password can still be secure if its significantly longer; think 20 characters or more.
If youre unsure aboutwhether your password is good enough, run it through Microsofts free password checker. Never use a password rated less than Strong.
You probably already have a login password for Windows on your PC, but that wont actually protect your data if somebody steals your computer or hard drivethe thief can simply plug your drive into another PC and access the data directly. If you have lots of sensitive information on your computer, you want to employ full-disk encryption, which protects all your data even if your hardware falls into the wrong hands.
Microsofts BitLocker software makes setting up full-disk encryption in Windows incredibly easyas long as your computer meets the following two criteria:
1. You have the Ultimate or Enterprise version of Windows 7 or Vista, or the Pro or Enterprise version of Windows 8.
2. Your computer has a TPM (Trusted Platform Module) chip.
The easiest way to see if your computer has a TPM chip is simply to attempt to enable BitLocker. Windows will let you know if you dont have one.
To enable BitLocker, go to Control Panel > System and Security > BitLocker Drive Encryption, or do a search for BitLocker in Windows 8. In the BitLocker menu, click Turn on BitLocker next to the drive(s) you wish to encrypt. Its as easy as that.
If your PC doesnt meet the requirements for BitLocker, you can still useTrueCrypt or DiskCryptor for free full-disk encryption.
For full-disk encryption of thumb drives and USB hard drives, you can use BitLocker To Go, which is designed for removable media. You still need a professional or enterprise version of Windows, but you dont need a TPM to use BitLocker To Go.
All you have to do is plug in the device you want to encrypt, and then once again go to the BitLocker menu. At the bottom of the menu, youll see the BitLocker To Go section, where you can click Turn on BitLockernext to the device.
Sometimes you want to encrypt your outgoing and incoming Internet traffic. If youre on an unsecured Wi-Fi network (at an airport, for instance), a hacker can intercept the data traveling to and from your laptop, which might contain sensitive information. To make that data useless to eavesdroppers, you can encrypt it, using a VPN.
A virtual private network creates a secure tunnel to a trusted third-party server. Data sent through this tunnel (either to or from your computer) is encrypted, so its safe even if intercepted. You can find Web-based VPNs that charge a small monthly fee but provide very easy access, or you can set up your own personal or business VPN.
The process of selecting or setting up a VPN is a little too long to describe here, so see ourarticle on VPN for beginners and experts alike.
If you or other people in your organization use Dropbox or SugarSync, youll be glad to know that those popular cloud storage services already encrypt your data, protecting it in transit and while it sits on their servers. Unfortunately, those same services also hold the decryption keys, which means that they can decrypt your files if, for instance, law enforcement directs them to do so.
If you have any really sensitive files in your cloud storage, use a second layer of encryption to keep them safe from prying eyes. The most straightforward way to do this is to use TrueCrypt to create an encrypted volume inside of your Dropbox. (For a complete guide to encrypting anything with TrueCrypt, see the end of this article.)
If you want to be able to access the data from other computers, consider putting a portable version of TrueCrypt in your Dropbox, as well. To do so, run the TrueCrypt installer; during the installation, choose the Extract option, and choose to put the extracted files in your Dropbox or other cloud storage.
