Encryption of Confidential Data
The ITS department would like to advise the Laurier community that
confidential information saved on latops, USB flash drives and home
computers must be encrypted to avoid disclosure due to theft, loss or
malware. See http://www.wlu.ca/page.php?grp_id=47&p=14275 for examples of bad things that can happen to USB drives and laptop computers.
All
laptop computers and home computers that are used to store Laurier
confidential information should be password protected and it is proper
to put passwords on important files. However, neither of these measures
provides enterprise level protection for confidential information. Hard
drives can be removed from computers and document passwords are
relatively easy to crack.
We recommend standard Windows XP
folder encryption for Laurier confidential information stored on
laptops and home computers. Encryption requires the NTFS file system.
Most systems installed in the last five years will be using NTFS.
A Windows folder is encrypted as follows:
1.
Right click on any Windows folder (we recommend creating a special
windows folder in directory C:\Documents and Settting\username\My
Documents)
2. Click on Properties
3. Click on Advanced
4. Check the Encrypt contents to secure data box
5. Click on OK
6. Click on OK
Once
a folder has been configured as encrypted, any file created in or moved
to that folder will also be encrypted. The files will be unreadable if
your disk drive is removed and connected to another third party
computer.
Only place important files in a confidential folder, there is usually no reason to encrypt pictures or music.
We
recommend that Laurier confidential information should only be saved on
a USB flash drive if that drive has hardware encryption. One such
device is called IronKey. A demo of Ironkey's capabilities can be
viewed at https://www.ironkey.com/demo.
Ironkey flash drives can be ordered from the the Bookstore. A hardware
encrypted USB flash drive can be used securely on any computer.
