정답: C
The most important responsibility of data owners when implementing a data classification process is determining appropriate user access levels (option C). This is because:
Data owners are the persons or entities that have the authority and responsibility for the business processes and functions that collect, use, store, and dispose of data1.
Data owners are accountable for ensuring that the data is handled in compliance with the applicable laws, regulations, policies, and standards, such as the GDPR and the PIPEDA1234.
Data owners are in the best position to determine the purpose and necessity of collecting and retaining data, as well as the risks and benefits associated with it1.
Data owners should consult with other stakeholders, such as the risk manager, the database administrator (DBA), and the privacy manager, to establish and implement appropriate data classification policies and procedures2.
Data classification is the process of organizing data in groups based on their attributes and characteristics, and then assigning class labels that describe a set of attributes that hold true for the corresponding data sets345.
Data classification helps organizations to identify, manage, protect, and understand their data, as well as to comply with modern data privacy regulations345.
Data classification also helps to determine appropriate user access levels, which means defining who can access, modify, share, or delete data based on their roles, responsibilities, and needs345.
Determining appropriate user access levels is the most important responsibility of data owners when implementing a data classification process, as it ensures that only authorized and legitimate users can access sensitive or important data. This provides confidentiality, integrity, availability, and accountability of data345.
Reviewing emergency changes to data (option A), authorizing application code changes (option B), and implementing access rules over database tables (option D) are not the most important responsibilities of data owners when implementing a data classification process. These are more related to the operational aspects of data management, which are usually delegated to other roles, such as the DBA or the IT staff. The data owner should oversee and approve these activities, but not perform them directly1.
