 Role of the System Owner:

The system owner is responsible for the overall operation and management of an application or system. This includes ensuring that technical controls are implemented and functioning as intended.

They have detailed knowledge of the system's architecture, the controls in place, and how those controls are applied within the system.

 Effectiveness of Technical Controls:

Assessing the effectiveness of a technical control requires understanding its implementation, configuration, and operational context.

The system owner is best positioned to provide this information as they manage and oversee the technical environment of the application.

 Comparing Other Roles:

Internal Auditor:While auditors review and evaluate the effectiveness of controls, they do so from an independent standpoint and might not have detailed, day-to-day operational insights.

Process Owner:The process owner focuses on business processes rather than technical controls specific to an application.

Risk Owner:The risk owner is responsible for managing risk but may not have the technical expertise or detailed operational knowledge of the system.

 Supporting Information:

According to the CRISC Review Manual, the system owner is often involved in the assessment and reporting of control effectiveness, especially regarding technical controls (CRISC Review Manual, Chapter 3: Risk Response and Mitigation, Section 3.1.3 Assessing Control Effectiveness) .
