HOWTO: Securing Your Laptop

Category: Laptops

The mobility and convenience that laptop computers provide has made it imperative for users to take steps to secure their laptops, and the data stored on them. There are several simple things that you can do to keep your laptop safe. Read on to learn how to protect your laptop from theft, snooping and data loss...

Laptop Security Tips

Over half a million laptops are stolen every year, from cars, coffee shops, college campuses, and hotel rooms. Keeping your laptop or netbook safe involves a combination of common sense, physical security devices, and software strategies.

Let's start with devices that make it harder for your portable computer to be carried off by someone else.

Physical security devices are used to keep your laptop from being stolen or used without your authorization. The most basic physical security device is a laptop security cable. This cable connects to your laptop and secures it to a non-moveable item in your office, hotel or conference room. For example, you can connect your laptop to your desk, or the leg of a conference room table.

The cables usually have a combination or key lock device, and attach to the security slot found on most notebook computers. Expect to pay about US$40 for a high-quality laptop security cable. A determined thief with a bolt cutter could foil this device, but it certainly makes it a lot harder to grab and run.

Another physical security device that you can add to your laptop is a theft protection plate. This plate, which applies like a sticker on steroids, is used to identify the owner of the computer and to prevent people from trying to resell your stolen computer. If the plate is removed then it leaves a permanent acid "tattoo" on the laptop, indicating that it has been stolen. These security plates are available from STOP for about $25.

Biometric devices can also be used to ensure that if your laptop is stolen, it can't be used by someone else. Biometric devices include fingerprint scanners and retinal scanners. These devices can be added to just about any laptop. The fingerprint scanner comes standard on some Toshiba laptops. I expect that in the next year or two, we'll see more mobile devices using facial or voice recognition. Some Android-based smartphones have the "face unlock" feature, and the latest iPhones offer fingerprint scanning.

Security Software

FrontDoor Software's Laptop Security software can help to get your laptop back if it's lost or stolen. The program displays ownership information at startup, and can also report tracking information to the owner if the laptop goes online. Also, if your laptop is stolen, you can login to the Front Door website and enter a lockdown code that will help to protect your information. You can even send a personal message to the thief, or cause an audible "This laptop was stolen!" alarm to be played. FrontDoor Laptop Security works on Windows and Mac OS X. The software has a free Basic version, and a Deluxe version with a 90-day free trial. Deluxe costs $30 for 3 year license.

Prey is a free cross-platform tracking app that runs on Windows, Linux, Mac, Android and iPhone/iPad devices. If your laptop or other mobile device is lost, Prey provides location data, Webcam, and screenshot reports. Prey can make your lost or stolen device sound a loud alarm, snap a photo of the person using your computer, or display a message onscreen. It can also lock down your device or wipe stored passwords, via remote command. The free version supports up to three devices.

Lojack for Laptops is another software-based laptop recovery product. This company provides you with a Theft Recovery Team that's actually a licensed private investigation agency. They will work with local law enforcement and Internet Service Providers, using information sent from the stolen computer, to assist local police in recovering your computer. They claim that 3 out of 4 stolen computers with Lojack for Laptops are recovered. LoJack for Laptops costs $39/year.

And of course, there's always the "inside job" that nobody sees coming -- the threat of hackers and snoops that attack through viruses and spyware. Every laptop should have an up-to-date anti-virus and anti-spyware software package installed, to identify and remove malware from your system. Read my companion article Should You Buy Anti-Spyware or Anti-Virus Software? for my recommendations to keep your computer safe from viruses, spyware and other threats.

File Encryption

File encryption is used to protect your data from hackers, thieves and others who may access your computer without permission. Windows Vista, Windows 7 and Windows 8 have BitLocker, which can be used to encrypt an entire hard drive. Other options for encryption are PGP Whole Disk Encryption, and the free TrueCrypt software, which can encrypt a hard drive partition, USB flash drive or external hard drive. Both PGP and TrueCrypt work on Windows, Mac and Linux systems. Learn more about the pros and cons of encryption in my related article Should You Encrypt Your Hard Drive?.

Password Security

In addition to physically securing your laptop and protecting your computer with security software, you also need to take steps to protect your laptop with strong passwords. While it is important to set up a user account password for your laptop you will also want to set up a power-on password. These passwords will prevent unauthorized people from logging in to your computer, or accessing it by using a boot-up disc. To create your and power-on password you will need to enter your BIOS security set-up menu. This is usually accessed by pressing the Del, F1 or F2 key while your computer is starting up. Try to use passwords that include a combination of at least eight letters and numbers, and stick to a password rotation schedule that changes your passwords on a regular basis. Make sure you remember the passwords, or you'll lock yourself out!

Here's one other point on passwords, particularly relevant for travelers. If you allow your web browser to store your passwords, and your laptop is stolen, you've given away the keys to the kingdom. Roboform and similar tools can keep all your passwords handy, but with the protection of a master password. See Is Your Password Hacker Proof? for more information on password strategies.

Keeping Your Laptop Safe

Here a few more practical tips you can use to secure your laptop and your data.

Consider using free Portable Apps that can be loaded on a USB flash drive. Using this approach, all your software and your personal files never need to be stored on the laptop's hard drive. This has the additional advantage that you can plug the flash drive into any available computer, and work without fear of leaving behind any personal data. Just be sure that the drive and the laptop don't travel together in the same bag.

If you'll have Internet access while traveling, an even better solution might be cloud-based apps and storage. By managing your email, documents and other tasks with free cloud-based services, all your data is stored online, and you don't need to carry a flash drive that could possibly get lost or stolen. See Eight Free Cloud Services You Should Try and Free Web-Based Photo Editors to get an idea of all the tools available.

And finally, if you use wifi while away from home, you need to take some extra security precautions. See my article The Big Problem With Free Wifi Hotspots to understand the risks, and learn how to protect against them.

To keep your laptop as safe as possible you will want to combine physical, software and use password strategies. While not all of the above security methods are applicable, practical or necessary for all laptop users, it is still important to understand what your security options are so that you can alter your security strategies as your computer use evolves.

Another good idea is to carry your laptop in a bag that doesn't look like a laptop carrying bag. Less likely to be stolen in the airport of coffeeshop that way. :-)

re: your comments about cloud-based apps. This is exactly why I bought a Chromebook. If my laptop gets stolen, there are no files of interest to a thief. Everything (both my files and my apps) is off in the cloud.

Hello Everyone!


Store all of your sensitive material in an Encrypted Password-Protected external Hard Drive and then within the Drive itself put these into a TrueCrypt volume. Thus, you will have Double Protection from prying eyes.

In addition, when using passwords of course use higher and lower case characters with an occasional Special Character (along with the space bar if the program allows it) and use only 7 OR 12 characters in your password configuration.
All passwords have the potential to be Cracked. However, 7 or 12 characters are harder to break!

I certainly hope that the above-stated Tips Help.

I thought security cables which had been cut by bolt cutters actually disabled the laptop. Not true?

EDITOR'S NOTE: Not the ones that I'm familiar with...

The free version of Prey is limited to 3 devices, not 10 as stated in the article.

EDITOR'S NOTE: Thanks, fixed now.

Interesting article, Bob. I have never wanted a laptop, due to the "issues" of not being able to upgrade, many of a laptops components, etc..

I also, would worry about using a laptop, any place other than my home. Laptops at "open" Wi-Fi places, is very scary to me. But, I have noticed that my Avast does have a program available, where you can use their VPN program, which does cost $59.95 a year. You must have Avast installed, either the Free or Pro or Internet Security or Premium versions, so that the VPN program can work, you can't just purchase this program, by itself.

For me, going VPN for a Laptop is the only way to go, especially if, you are going to be flexible in your usage of Wi-Fi places. I know that some students will go to McDonald's, not only for a quick meal, but, to use their Wi-Fi. Many other places have Wi-Fi available, like Starbucks stores and other coffee shops.

So, I would check into VPN programs, that will also, help to protect your laptop, when you are using it, in other places, besides home. I also think, using a VPN at the college would be safer usage. I am not to sure, just how safe the Wi-Fi setup at Colleges and Universities really are. For me, it is always better to be safe, than sorry. :)
