The loss of restricted data is one of the greatest risks to the University of Illinois and everyone affiliated with the University. You can help make sure that your data are correctly classified and kept safe.  To better understand how to classify your data, review the definitions of each data type.

Is Your Data at Risk?

Data that are high-risk or sensitive need extra care. Use the Data Classification Questionnaire to properly classify your data.  

Once your data are classified, you will be able to better understand how those data can be used in the safest possible way.

If your data are classified as high risk, sensitive, or restricted, ask yourself the following questions to help lower the risk of data breach or loss:

  1. Do I  need to make a copy of sensitive data?
    • If you can view the restricted data without making a copy on your own computer or making a print copy, do that instead.  Data classified as high risk cannot be stored on your computer unless special permissions are obtained.
  2. Do I need to share restricted data with someone else?
    • In addition to creating more copies, transmitting restricted data creates the risk that it will be intercepted. Data classified as sensitive cannot be emailed without encryption. Data classified as high risk cannot be emailed.
  3. How long do I need to keep a copy of restricted data?
    • Unless you need to use the same restricted data on a regular basis (once a week or more), destroy or securely archive any copies.
