01.04 General Description (purpose...

Phase 1 - A suggested method would be to include in your policy, a statement that explicitly defines the purpose of your system and how it aligns with protecting Controlled Unclassified Information (CUI). This statement should articulate the system's intended function, the types of CUI it processes, stores, or transmits, and how it contributes to your organization's mission while adhering to NIST 800-171 Revision 3 requirements. For example, you could say something like, "This system, designated [System Name], is intended to support [Organization Mission/Business Function] by processing, storing, and transmitting CUI related to [Specific CUI Categories, e.g., technical drawings, contract information, etc.]. Its purpose is to facilitate [Specific Activities, e.g., design collaboration, proposal development, etc.] while ensuring the confidentiality, integrity, and availability of CUI in accordance with NIST 800-171 Revision 3 and applicable federal regulations." This demonstrates a clear understanding of the system's role in handling CUI and the importance of its protection.

The example above provides good guidelines.
