Explanation
The main reason for having senior management review and approve an information security strategic plan is to ensure that the plan aligns with the corporate governance of the organization. Corporate governance is the set of responsibilities and practices exercised by the board and executive management to provide strategic direction, ensure objectives are achieved, manage risks appropriately and verify that the organization's resources are used responsibly1. An information security strategic plan is a document that defines the vision, mission, goals, objectives, scope and approach for the information security program of the organization2. The plan should be aligned with the organization's business strategy, risk appetite, culture, values and objectives3. By reviewing and approving the plan, senior management demonstrates their commitment and support for the information security program, ensures its alignment with the corporate governance, and provides the necessary resources and authority for its implementation4.

Senior management review and approval of an information security strategic plan is important to ensure that the plan is aligned with the organization's overall corporate governance objectives. It is also important to ensure that the plan takes into account any legal and regulatory requirements, as well as the resources and staff needed to properly implement the plan.
