1. Purpose of Procedure
This document outlines a method to classify data according to risk to the University of Wisconsin System and assign responsibilities and roles that are applicable to data governance.
2. Responsible UW System Officer
Associate Vice President (AVP) for Information Security
The definition for High, Moderate, and Low Data can be found in UW System Administrative Policy 1031, Information Security: Data Classification and Protection.
The definition for Data Steward can be found in the UW System Information Security System.
Compensating Control: A data security measure that is designed to satisfy the requirement for some other security measure that is deemed too difficult or impractical to implement and that meets the intent and rigor of the original control.
A. Data steward requirements
These standards establish a minimum baseline for data classification across UW System. Each institution shall identify a qualified Data Steward(s) for each data domain controlled by the institution. For the purpose of these standards, it is the responsibility of the Data Steward to work with Security, Privacy, and/or Data Officers to assure that the data is classified appropriately.
i. UW System will provide Data Steward training materials. Each institution shall train their Data Stewards to ensure that they understand their responsibilities and to enhance consistent classification of data.
ii. Each data steward must identify the major system(s) where their data resides, classify those systems according to the classifications defined in UW System Administrative Policy 1031, Information Security: Data Classification and Protection, document this classification in a hard copy or electronic format, and ensure appropriate controls and implemented.
iii. Data stewards shall review data classification(s) at least annually (365 days).
Data covered by the Family Educational Rights and Privacy Act (FERPA) may contain elements from multiple classifications (i.e. data sets). The composition of these data sets may result in either a moderate or a high risk data classification. In these cases, protections prescribed by federal law will take precedence.
C. Data Element Examples
I. High Risk:
- information protected from unauthorized disclosure by legislation such as the Health Insurance Portability and Accountability Act (HIPAA), or industry standards such as Payment Card Industry Data Security Standard (PCI DSS);

- University information that is statutorily exempt from public records requests per s. 19.31, Wis. Stats.
II. Moderate Risk:
- information that is proprietary or produced only for use by members of the UW System community, such as project plans, email reports, and procedure documents plans;
- student educational records without identifying references;
- FERPA-related information not specifically classified as high risk;
- institutionally developed and/or owned computer applications and/or source code not designated as in the public domain;
- directory information for employees who have chosen to withhold their personal information;
- information used for internal purposes or exchanged pursuant to contract that is not considered high risk, such as drafts;
- donor or other third-party partner information maintained by the University;
- proprietary financial, budgetary or personnel information not explicitly authorized for public release;
- emails and other communications regarding internal UW System matters which have not been specifically approved for public release;
- unpublished research data not considered high risk.
III. Low Risk:
