Correct Answer: DThe Clark-Wilson model is designed to enforce integrity through control mechanisms that ensure data is modified only in specific, legitimate ways. It includes mechanisms for implementing segregation of duties (SoD), which ensures that no single individual can control the entire process, thereby reducing the risk of fraud. By enforcing well-formed transactions and integrity constraints, the Clark-Wilson model is particularly effective in protecting the integrity of data while also addressing separation of duties. Therefore, it is the best choice for the given scenario.
