Introduction

Include a detailed topology narrative and graphic that clearly depicts the system boundaries, system interconnections, and key devices. (Note: this does not require depicting every workstation or desktop, but include an instance for each operating system in use, an instance for portable components (if applicable), all virtual and physical servers (e.g., file, print, web, database, application), as well as any networked workstations (e.g., Unix, Windows, Mac, Linux), firewalls, routers, switches, copiers, printers, lab equipment, handhelds). If components of other systems that interconnect/interface with this system need to be shown on the diagram, denote the system boundaries by referencing the security plans or names and owners of the other system(s) in the diagram.

Phase 1 - To comply with NIST 800-171 Revision 3's System Environment (SE) requirements, it is suggested that your policy clearly define and document the boundaries of your system environment processing, storing, or transmitting Controlled Unclassified Information (CUI). This should include a detailed description of all hardware, software, and firmware components within the environment, specifying their purpose and how they interact. I also recommend outlining procedures for managing and controlling changes to the system environment, including how new components are authorized and integrated. Finally, the policy should address regular assessments and monitoring of the system environment to ensure its continued security posture and compliance with NIST 800-171 requirements, including how you handle any deviations or anomalies.
