Who is primarily responsible for the approval of an information security policy?

The approval of an information security policy typically falls under the purview of the board of directors. This is because the board has the ultimate responsibility for the organization's governance and risk management, which includes protecting the organization's assets and ensuring compliance with relevant laws and regulations. By approving the information security policy, the board demonstrates its commitment to the security framework and provides the necessary oversight to ensure that the organization effectively mitigates risks associated with information security.

The involvement of the board is critical, as they are positioned to allocate resources, establish priorities, and provide the necessary support for security initiatives. Their approval signifies that the policy is aligned with the organization's strategic objectives and risk tolerance.

While the IT department, security committee, and security administrator may contribute to the development and implementation of the policy, their roles are typically more operational or advisory. They may help draft the policy and suggest measures based on technical expertise or industry best practices, but without board approval, the policy may lack the authority and organizational backing needed for effective enforcement and compliance.
