1. Policy Purpose
The purpose of this policy is to establish a method of categorizing data assets based on risk to the University of Wisconsin (UW) System and to establish specific minimum standards for data handling across the UW System. This policy also ensures that the UW System manages data in a consistent and appropriate manner.
2. Responsible UW System Officer
Associate Vice President for Information Security
This policy applies to all University of Wisconsin System data. To the extent possible, the elements of section 6 of this policy should be incorporated into contracts with third party providers.
The President of the University of Wisconsin System is empowered to establish information security polices under Regent Policy Document 25-5, Information Security: Information Technology. The UW System is committed to a secure information technology (IT) environment in support of its mission. In order to establish the safeguards required for particular types of data, it is necessary to determine the level of risk associated with the data. Data classification assigns such levels and determines the extent to which technical, administrative, and physical controls should be applied to protect the data from theft, alteration, loss of integrity, and/or misuse. Proper data security handling must be implemented commensurate with the sensitivity of the data and the risk to the UW System. This policy also seeks to ensure strong and consistent data handling standards throughout the UW System. This ensures appropriate protection from threats to the confidentiality, integrity, and availability of the UW System’s data.
The following definition can be found in the UW System Information Security Program:
- Data Steward
6. Policy Statement
A. Data Classification
Data may be classified as:
i. High Risk: The loss of confidentiality, integrity or availability of data that could result in a significant or catastrophic impact to individuals, mission, assets, or operations of UW System.
ii. Moderate Risk: The loss of confidentiality, integrity or availability of data that could result in a serious impact to individuals, mission, assets, or operations of UW System.
iii. Low Risk: The loss of confidentiality, integrity, or availability of data that could result in minimal impact to individuals, mission, assets, or on the operations of UW System.
The Data Steward(s) of each institution shall evaluate and classify data for which he, or she, is responsible for according to the definitions in this policy and the standards specified in UW System Administrative Procedure 1031.A, Information Security: Data Classification Standard. A Data Steward may classify specific data elements at a higher level than identified in the procedure. A Data Steward may not reclassify to a lower level any data that is specifically classified in the procedure.
B. Data Protection
All information shall be kept in a manner consistent with appropriate controls, and standards commensurate with its data classification and the protections outlined in UW System Administrative Procedure 1031.B, Information Security: Data Protection Standard.
Information shall also be maintained according to appropriate UW System record retention policies, applicable state and federal laws and regulations.
Family Educational Rights and Privacy Act (FERPA) data may contain elements from multiple classifications (i.e. data sets). The composition of these data sets may result in either a high or moderate risk data classification. In these cases, protections prescribed by federal law will take precedence.
