The control owner is the person who has the authority to approve an exception to a control. A control is a policy, procedure, or technical measure that is implemented to prevent or mitigate a risk. A control owner is responsible for the design, implementation, operation, and maintenance of the control, as well as for monitoring and reporting its performance and effectiveness. A control owner is also accountable for the approval of any changes or exceptions to the control, based on the risk assessment and business justification.
An information security manager, a risk owner, and a risk manager are not the best choices, as they do not have the same level of authority, responsibility, and knowledge as the control owner in relation to the control. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 35.

In this context, the internal IT team acts as data custodians. Data custodians are responsible for the safe custody, transport, storage, and overall safeguarding of data. They ensure that data is properly maintained and that access controls are in place, but they do not make decisions about data usage-that responsibility lies with data owners.

The asset owner is the best suited to assist a risk practitioner in developing a relevant set of risk scenarios.
The asset owner is the person who has the authority and responsibility for the IT assets that support the business processes. The asset owner can provide valuable information on the business objectives, requirements, and expectations that the IT assets should meet. The asset owner can also help identify the potential threats, vulnerabilities, and impacts that may affect the IT assets and the business processes. The asset owner can also suggest possible risk responses and mitigation strategies to address the risk scenarios.
The other options are not as relevant as the asset owner, as they may not have the same level of knowledge, interest, or involvement in the IT assets and the business processes.

Read rights: The permission to view or access the content of a file or a folder1.
Application files: The files that contain the code, data, or resources of an application or a program2.
Controlled server environment: A server environment that is managed and secured by a set of policies, procedures, and tools3.
Business process owner: The person who is responsible for the design, execution, and performance of a business process.
Read rights to application files in a controlled server environment should be approved by the business process owner. The business process owner is the person who has the authority and accountability for the business process that uses or depends on the application files. The business process owner should approve the read rights to application files in a controlled server environment to:
Ensure that the read rights are aligned with the business needs and objectives Prevent unauthorized or unnecessary access to the application files Protect the confidentiality, integrity, and availability of the application files Comply with the relevant laws and regulations that govern the access to the application files The other options are not the best choices for approving the read rights to application files in a controlled server environment, because they do not have the same level of authority, responsibility, or knowledge as the business process owner. The database administrator, who is the person who manages and maintains the database systems and data, may have the technical skills and access to grant the read rights to application files, but they may not have the business insight or approval to do so. The chief information officer, who is the person who oversees the IT strategy and operations of the organization, may have the executive power and oversight to approve the read rights to application files, but they may not have the specific or detailed knowledge of the business process or the application files. The systems administrator, who is the person who configures and maintains the server systems and networks, may have the administrative privileges and tools to grant the read rights to application files, but they may not have the business understanding or authorization to do so.

Risk strategies are the plans and actions that an organization adopts to manage its risks and to achieve its objectives. Risk strategies should be aligned with the organization's vision, mission, values, and culture, as well as its internal and external environment. The most important consideration when developing risk strategies is the long-term organizational goals, meaning that the risk strategies should support and enable the organization to pursue and attain its desired future state and outcomes. The long-term organizational goals should guide the risk identification, assessment, response, and monitoring processes, as well as the risk appetite and tolerance levels. The long-term organizational goals should also be communicated and cascaded throughout the organization to ensure the risk awareness and engagement of all stakeholders.
