Exam CISA Topic 1 Question 328 Discussion

Explanation/Reference:
Explanation:
Data classification is necessary to define access rules based on a need-to-do and need-to-know basis.
The data owner is responsible for defining the access rules; therefore, establishing ownership is the first step in data classification. The other choices are incorrect. A criticality analysis is required for protection of data, which takes input from data classification. Access definition is complete after data classification and input for a data dictionary is prepared from the data classification process.
