organization-defined device

A placeholder value in a security or privacy control statement — specifically an **assignment operation** — that an implementing organization fills in during tailoring to name the exact endpoints, hardware types, or classes of endpoint (workstations, servers, mobile devices, IoT sensors, personally-owned BYOD assets, etc.) to which the control applies. It is the variable part of a control or control enhancement that is instantiated by an organization during the tailoring process by assigning an organization-defined value or selecting a value from a predefined list. The expression's force is not "a device of a particular kind" but rather "whichever devices or device types the organization has formally decided belong inside the scope of this requirement": devices requiring identification and authentication are defined by type, device, or a combination, and the category explicitly includes devices not owned by the organization. In practice it gives organizations the latitude described by NIST SP 800-53: organizations can restrict the application of the control to a limited number or type of devices based on mission or business needs, while still committing to a specific, auditable scope once the parameter is set. Once specified, the values for the assignment and selection statements become a permanent part of the control.
