The most important factor to ensuring information stored by an organization is protected appropriately is assigning information asset ownership. Information asset ownership is the process of identifying and assigning the roles and responsibilities of the individuals or groups who have the authority and accountability for the information assets and their protection. Information asset owners are responsible for defining the business value, classification, and security requirements of the information assets, as well as granting the access rights and privileges to the information users and custodians. Information asset owners are also responsible for monitoring and reviewing the security performance and compliance of the information assets, and reporting and resolving any security issues or incidents. By assigning information asset ownership, the organization can ensure that the information assets are properly identified, categorized, protected, and managed according to their importance, sensitivity, and regulatory obligations.
