This Excel tool is the engagement primary working deliverable. The member classifies an environment across four dimensions (connectivity, autonomy, control authority, and technology ownership) and the tool derives an enforceability verdict for a set of OT security controls, flagging which can be centrally enforced, which must be enforced locally, and which are infeasible. The member then validates relevant threat vectors, assigns ownership for every control, and records a defensible decision for each one.
