SBD has 150 staff collaborating on internal engineering projects. Its enterprise services system provides identity, name resolution, project file access, administration, logging, and backup.
What is inside the boundary?
Logical services and relationships; not a physical topology. Endpoints access project files. Servers forward logs to the collector. Workloads send recovery data to the backup repository.
Outside dependencies: facilities, power, approved software sources, and personnel notifications. Information crosses the boundary only through manual, human-controlled transfers using approved removable media. There is no external DNS forwarding or automated HR connection. Record transfer approvals, content checks, and the responsibilities for each dependency.
Working assumptions
- Internal project files, identity records, and logs are the principal information types.
- The starting impact levels are Moderate confidentiality, Low integrity, and Low availability (MLL). The Categorize guidance explains the records and rationale to develop with the information owner.
- The series uses NIST RMF and SP 800-53 Rev. 5 as the teaching framework. It does not assume that a private enterprise is legally required to use federal RMF.
- No classified, CUI, or real personal information is used. DoD, SAP, and other environments require their applicable authority-specific guidance.
The people making the decisions
The system owner is accountable for the system. The information owner explains business impact. The identity and operations leads implement safeguards. The assessor evaluates effectiveness. The authorizing official makes the risk decision. Privacy and common control providers contribute where applicable.
Keep the records aligned with the system
As this network changes, keep its description, risk analysis, assessment results, and corrective actions in step. The Body of Evidence & Artifacts guide brings the lifecycle responsibilities and record maintenance together.
