The information classification policy is the most important document regarding the treatment of sensitive data, because it defines the categories and criteria for classifying data according to their sensitivity, confidentiality, and value to the organization, and specifies the appropriate handling and protection measures for each category. Sensitive data are data that contain personal,proprietary, or confidential information that may cause harm or damage to the organization or its stakeholders if disclosed, modified, or destroyed without authorization. An information classification policy helps to ensure that sensitive data are identified and treated in a consistent and secure manner, and that the organization complies with the applicable laws andregulations regarding data protection and privacy. An encryption policy, an organization risk profile, and a digital rights management policy are all useful documents for the treatment of sensitive data, but they are not the most important document, as they do not directly address the classification and handling of sensitive data.
