Knowing what data you have and its sensitivity is your first step to ensure that it is adequately protected.

Based on APS 2.2, UW units are required to classify personal data to convey the level of risk and corresponding data protection that must be applied to the data. Definitions are available in APS 2.4 and on the Data Classifications page. The Office of Information Security is in the early stages of updating data classification processes to support UW units and will be engaging the UW-IT Security & Privacy and Data Governance boards.
