Assigning ownership is the best way to enable an effective information asset classification process, as it establishes the authority and responsibility for the information asset and its protection. The owner of the information asset should be involved in the classification process, as they have the best knowledge of the value, sensitivity, and criticality of the asset, as well as the impact of its loss or compromise. The owner should also ensure that the asset is properly labeled, handled, and secured according to its classification level. (From CISM Review Manual 15th Edition)
