The first step to strengthen and enforce current data governance practices after a data leakage incident is to verify data owners. Data owners are the individuals or groups who have the authority and responsibility to define, classify, protect, and manage the data assets of an enterprise1. By verifying data owners, the enterprise can ensure that the data is properly accounted for, categorized, and secured according to its value, sensitivity, and risk. Data owners can also establish data policies, standards, and procedures, as well as monitor and report on data quality, usage, and compliance1. Verifying data owners is a prerequisite for assessing data security controls, reviewing data logs, and analyzing data quality, as these activities depend on the accurate identification and assignment of data ownership roles and responsibilities. References: CGEIT Review Manual (Digital Version) or CGEIT Review Manual (Print Version), Chapter 4: Risk Optimization, Section 4.2: IT Risk Management Process, Subsection 4.2.1: IT Risk Identification, Page 163-164. Top 10 Effective Data Governance Tools.
