📖 What is Data Owner?
A Data Owner is a senior-level individual with ultimate accountability for a specific dataset. They define data access policies, determine security requirements, and authorize data usage, ensuring alignment with business objectives and regulatory compliance. They are responsible for the data’s value and risk.
"The exam will differentiate between Data Owner and Data Custodian responsibilities. The Data Owner is a business stakeholder, not an IT professional. Focus on their decision-making authority regarding data access and usage, not technical implementation."

🔑 What are the Key Concepts of Data Owner?
- ▸ Data Owners are business leaders, not IT staff; they establish data policies based on business value and risk tolerance.
- ▸ They define acceptable data usage, including who can access, modify, and share the data, aligning with legal and ethical guidelines.
- ▸ Data Owners approve data access requests, ensuring compliance with established policies and regulatory requirements like GDPR or HIPAA.
- ▸ They are accountable for data breaches or misuse related to their assigned datasets, even if implemented by a Data Custodian.
- ▸ A key responsibility is classifying data based on sensitivity (e.g., public, confidential, restricted) to determine appropriate security controls.

❓ Frequently Asked Questions
How does a Data Owner work with a Data Custodian?
The Data Owner sets the *policies* for data access and security. The Data Custodian *implements* those policies using technical controls. They are a collaborative partnership, not a replacement.
What happens if a Data Owner isn't clearly identified for a dataset?
This creates a significant risk. Without ownership, there's no accountability for data quality, security, or compliance, potentially leading to legal and financial repercussions.
Can a Data Owner delegate their responsibilities?
While they can delegate *tasks*, the Data Owner retains ultimate accountability. Delegation doesn't absolve them of responsibility for data security and compliance within their domain.
