The organization's risk appetite is the most important factor to consider when defining control objectives, because it reflects the amount and type of risk that the organization is willing to accept or avoid in pursuit of its goals. Control objectives should align with the risk appetite and support the achievement of the organization's objectives. Industry best practices, an information security framework, and control recommendations from a recent audit are also useful sources of guidance, but they are not as critical as the risk appetite.
