  "id": "MLC-T-CYB-004191",
  "term": "system element",
  "field": "Cybersecurity",
  "definition": "1. A hardware, software, or firmware part or element of a larger system with well-defined inputs and outputs and a specific function.\n\n2. A hardware, software, firmware part or element of a larger PNT system with well-defined inputs and outputs and a specific function.\n\n3. Smallest selectable set of elements on which requirements may be based.\n\n4. See system component.\n\n5. Member of a set of elements that constitute a system.\n\n6. Member of a set of elements that constitute a system.\nNote 1: A system element can be a discrete component, product, service, subsystem, system, infrastructure, or enterprise.\nNote 2: Each element of the system is implemented to fulfill specified requirements.\nNote 3: The recursive nature of the term allows the term system to apply equally when referring to a discrete component or to a large, complex, geographically distributed system-of-systems.\nNote 4: System elements are implemented by: hardware, software, and firmware that perform operations on data/information; physical structures, devices, and components in the environment of operation; and the people, processes, and procedures for operating, sustaining, and supporting the system elements.\n\n7. See system element.",
