In which area are data owners PRIMARILY responsible for establishing risk mitigation?

Data owners primarily focus on the management and protection of the information they are responsible for, making entitlement changes a critical area where they establish risk mitigation. Entitlements define the level of access that users have to sensitive data and systems, which is essential for maintaining data confidentiality, integrity, and availability.

By managing entitlement changes, data owners can ensure that only authorized individuals have access to specific information. This involves defining user permissions, roles, and ensuring that access controls are properly enforced. Such measures are essential to prevent unauthorized access and potential data breaches, thereby directly contributing to effective risk mitigation.

In contrast, the other options relate to broader security measures or specific technical controls that may not be directly under the purview of data owners. While platform security, intrusion detection, and antivirus controls are critical components of a comprehensive security program, they fall more into the domain of IT security teams and technical specialists who implement and manage these controls, rather than data owners who focus on the governance of data access and management.
