Ranking Evidence Types for CUI Flow Authorizations

For assessment objective [d] "authorizations for controlling the flow of CUI are defined," here's my ranking of evidence types based on the CMMC assessment objects:

Evidence Type Ranking

1. **Documentation (Highest Priority)**

  - List of information flow authorizations 
  - Access control policy sections on authorization requirements
  - System connection or processing agreements
  - System security plan sections on authorization processes
  - Approval documentation for CUI flow paths
  - Account management documents with authorization details

2. **Interview Evidence (Medium Priority)**

  - Interviews with personnel responsible for defining authorizations
  - Discussions with system administrators about authorization processes
  - Information from security personnel on approval workflows

3. **Technical Testing Evidence (Supporting Priority)**

  - Configuration evidence showing implemented authorization rules
  - Screenshots of authorization tables or matrices
  - System settings that enforce defined authorizations

Assessment Approach Prioritization

For this objective, I recommend prioritizing assessment approaches as follows:

1. **Examine (First)**: Start by examining formal documentation of authorizations since this objective specifically focuses on whether authorizations are "defined." This includes reviewing policies, procedures, and authorization records that formally establish who/what is permitted to transmit CUI.

2. **Interview (Second)**: After reviewing documentation, interview personnel responsible for defining and managing authorizations to understand how the organization determines who is authorized to control CUI flow.

3. **Test (Third)**: While technical validation is still important, it serves more as supporting evidence for this objective, as it focuses more on enforcement (objective [e]) than on definition.

This objective focuses specifically on the formal definition of who or what is authorized to control the flow of CUI. Strong documentation showing clearly defined authorization requirements, roles, and processes will be your most compelling evidence. The technical implementation of these authorizations becomes more critical for objective [e].
