Who is generally responsible for determining the classification of an information asset?

The asset owner is typically responsible for determining the classification of an information asset because they have the best understanding of the asset's sensitivity, value, and the potential impact that its unauthorized disclosure, modification, or destruction could have on the organization. The asset owner is often an individual or group who has the authority and accountability for the information asset's lifecycle, including its creation, use, sharing, storage, and eventual disposal.

By classifying information assets, the asset owner helps establish the security requirements and ensures that appropriate controls are implemented based on the classification level. This process involves assessing the data's criticality to the organization's operations and evaluating legal, regulatory, and contractual obligations from a data protection perspective.

While other roles, such as the asset custodian, the security manager, and senior management, may provide input or guidance on classification policies and practices, the ultimate responsibility lies with the asset owner. This delineation of responsibility is crucial for effective information risk management, as it ensures that individuals with the most relevant knowledge and authority over the asset make informed decisions regarding its classification.
