Final answer:
The CEO typically approves the incident response policy of an organization, following its development and recommendation by the CIO and CSO. The CEO's role is to ensure that all strategic operations, including security policies, align with the company's goals.
Step-by-step explanation:
The individual responsible for approving the incident response policy of an organization is generally the Chief Executive Officer (CEO). The CEO holds the highest rank in the management hierarchy and is responsible for ensuring that the company's overall operations align with its strategic goals, which includes overseeing the readiness and response to incidents that could affect the company's information security.
The Chief Information Officer (CIO) often develops or manages the development of the policy in conjunction with the Chief Security Officer (CSO), who is responsible for the organization's security posture. The Human Resources Manager might be involved in the incident response process particularly in handling the personnel aspects, but they would not generally be responsible for approving the policy. Once drafted and recommended by these executives, the CEO usually approves the policy to ensure that it fits the organization's strategic vision and legal obligations.
