CSI: UW Episode 4
The Scene of the
Laptop Crime
SCENARIO 1 : You’re at the airport, and you put your laptop
through the scanner. Someone grabs it and runs before you pass through. Your
stolen laptop contains your personal banking information and account access.
SCENARIO 2 : You’re in the library with your laptop and you
get up to grab a book off the shelf. When you return your laptop is gone. Your
stolen laptop contains enough information for someone to steal your identity.
These are just 2 possible scenarios in which thieves or unauthorized users
could get access to sensitive and/or personal information on your machine. How
could access to your information be prevented? Here are some tips for keeping
your machine more secure and preventing unauthorized access.
Your Personal Laptop
If your laptop is stolen and/or accessed by an unauthorized user, it can be a
disaster. Here are some tips to protect your laptop and your data.
- Lock up your laptop when it’s not in use. If your laptop isn’t in a
physically secure area, it should be locked away. Even if you think the area
is safe, keep in mind that others may have keys and could gain access.
- Use a strong password. A strong password can stop others from accessing
your files and hard drive. Use a mixture of at least 8 characters including
uppercase and lowercase letters, numbers, and symbols.
- Do not have your browser remember passwords. If your browser remembers
them, anyone who gains access to your computer can gain access to the sites
you visit.
- Encrypt your hard drive contents. Windows XP Professional contains the
Encrypting File System (EFS) which allows you to encrypt files and folders
on your computer. EFS should only be used on personally owned computers not
connected to UW’s network. You can also use the TrueCrypt product for more
secure encryption on your computer. Linux users can encrypt their drives
using a variety of products available on the web. Mac OS X users can use
FileVault to encrypt their hard drive data. You should back up your personal
encryption certificates and keys to disk or CD and store them in a safe
location. Warning!: If you forget your password, your data can be lost
forever! *
- Install a BIOS password. This makes it harder for thieves to get at your
data.
- Invest in recovery software. Software that silently calls home when a
stolen laptop is reconnected to a network may help authorities recover your
lost equipment.
- Don’t store sensitive or personal information on the laptop. Save as
little as possible on the laptop itself. If you are traveling with your
laptop, only load the files you need during your trip. Sensitive information
for business related activities should remain on UW servers. Use VPN to get
to them from afar. Personal information such as passwords, credit card
information, and other sensitive files should not be stored on the laptop if
it can be avoided.
- Be cautious of public use wireless and hardwired networks. If a wireless
network does not include security, a huge potential for data theft exists.
If you are in a public area on a wireless network such as a hotel or cafe,
never login to sensitive web sites unless the site is using a Secure Socket
Layer (SSL) designated by HTTPS. Be wary of using a VPN client unless you
know all network traffic is encrypted. For further information on VPN at UW,

- Report incidents. If you fall victim to laptop theft notify the
authorities immediately.
Laptops for Checkout
Laptops may often be checked out from libraries or other locations. At UW,
laptops may currently be checked out at Coe Library and the Geology Library, and
select college programs. When you check out a laptop, make sure that you shut it
down after use so it is refreshed for the next user and does not contain any of
your personal documents or information. Do not save any personal information on
a checked out laptop.
*Information Technology is unable to provide support for, or recovery from,
encrypted file systems at this time. IT is working to implement system utilities
that will provide a backup for lost keys for supported Windows Operating
Systems.
