The chief information officer (CIO) is the most likely person to be responsible for the coordination between the IT risk strategy and the business risk strategy, because the CIO is the senior executive who oversees the information technology (IT) function and aligns it with the organization's strategy, objectives, and operations.
The CIO is also responsible for ensuring that the IT function delivers value, supports innovation, and manages IT risks effectively and efficiently. The CIO can coordinate the IT risk strategy and the business risk strategy by communicating and collaborating with other business leaders, establishing and implementing IT governance frameworks and policies, and monitoring and reporting on IT performance and risk indicators.
The other options are not as likely as the CIO to be responsible for the coordination between the IT risk strategy and the business risk strategy, because they have different or limited roles and responsibilities in relation to IT and business risk management, as explained below:
A: Chief financial officer (CFO) is the senior executive who oversees the financial function and manages the financial risks of the organization. The CFO may be involved in the coordination between the IT risk strategy and the business risk strategy, especially when it comes to budgeting, funding, or reporting on IT-related projects and initiatives, but the CFO is not the primary person who oversees the IT function and aligns it with the organization's strategy and objectives.
B: Information security director is the senior manager who oversees the information security function and manages the information security risks of the organization. The information security director may be involved in the coordination between the IT risk strategy and the business risk strategy, especially when it comes to protecting the confidentiality, integrity, and availability of the information assets and systems, but the information security director is not the primary person who oversees the IT function and aligns it with the organization's strategy and objectives.
C: Internal audit director is the senior manager who oversees the internal audit function and provides independent assurance on the effectiveness and efficiency of the organization's governance, risk management, and control processes. The internal audit director may be involved in the coordination between the IT risk strategy and the business risk strategy, especially when it comes to auditing, reviewing, or testing the IT- related processes and controls, but the internal audit director is not the primary person who oversees the IT function and aligns it with the organization's strategy and objectives.

The recovery time objective (RTO) is the planned recovery time for a process or system which should occur before reaching the business process's maximum tolerable downtime (MTD) or maximum allowable outage (MAO). The RTO must be aligned with the MAO to ensure that the continuity of the business process is not compromised by a prolonged outage. The RTO is determined by the business impact analysis (BIA) based on the criticality and urgency of the business process and its dependencies. The RTO also helps to select and implement appropriate recovery methods and procedures for the process or system.

According to the GDPR, personal data shall be collected for specified, explicit and legitimate purposes and not further processed in a manner that is incompatible with those purposes1. This means that a business unit can only use personal information for a different purpose if it has obtained the consent of the data subject, or if it has a clear legal basis or obligation to do so2. Therefore, informed consent should be the first consideration when a business unit wants to use personal information for a purpose other than for which it was originally collected.

Regulatory requirements should be the primary basis for deciding whether to disclose information related to risk events that impact external stakeholders, because they define the rules or standards that the organization must comply with to meet the expectations of the regulators, such as government agencies or industry bodies, and to avoid legal or reputational consequences. A risk event is an occurrence or incident that may cause harm or damage to the organization or its objectives, such as a natural disaster, a cyberattack, or a human error. An external stakeholder is a person or group that has an interest or influence in the organization or its activities, but is not part of the organization, such as customers, suppliers, partners, investors, or regulators. Disclosing information related to risk events that impact external stakeholders is a process of communicating or reporting the relevant facts or details of the risk events to the affected or interested parties. Disclosing information related to risk events may have benefits, such as maintaining trust, transparency, and accountability, but it may also have drawbacks, such as exposing vulnerabilities, losing competitive advantage, or inviting litigation. Therefore, regulatory requirements should be the primary basis for deciding whether to disclose information, as they provide the legal and ethical obligations and boundaries for the disclosure process.
Stakeholder preferences, contractual requirements, and management assertions are all possible factors for deciding whether to disclose information related to risk events, but they are not the primary basis, as they may vary or conflict depending on the situation or context, and may not override the regulatory requirements.

When a risk is accepted, it must be documented in the risk register-including rationale, alternatives evaluated, decision-makers, and contextual factors. This aligns with governance and audit accountability requirements in ISACA guidance.
