The board of directors is ultimately responsible for the organization's information and is tasked with responding to issues that affect its protection.

The data custodian is responsible for the maintenance and protection of data.

This role is usually filled by the IT department.

The chief information security officer (CISO) is responsible for security and carrying out senior management's directives.

The chief information officer (CIO) is responsible for information technology within the organization and is not ultimately responsible for the organization's information.

The ultimate responsibility for an organization's information rests with the organization's Board of Directors. The Board of Directors is responsible for setting the overall direction and strategy of the organization, and ensuring that the organization operates in accordance with legal and regulatory requirements, ethical principles, and accepted best practices.

In terms of information security, the Board of Directors is responsible for ensuring that the organization has appropriate policies and procedures in place to protect sensitive information, and that those policies and procedures are being followed. This includes setting the overall information security strategy for the organization, approving information security policies and standards, and ensuring that appropriate resources are allocated to support information security efforts.

While the Chief Information Officer (CIO) and the Chief Information Security Officer (CISO) play important roles in managing an organization's information, they are not ultimately responsible for it. The CIO is responsible for the overall management of an organization's IT infrastructure, while the CISO is responsible for the organization's information security program. However, both the CIO and CISO report to the Board of Directors and are accountable to them for the effectiveness of the organization's information security program.

The data custodian, on the other hand, is responsible for the day-to-day management and protection of specific types of information, such as customer data or financial records. They are responsible for ensuring that the data is accurate, up-to-date, and secure, but they do not have ultimate responsibility for the organization's information as a whole.
