“Every assessment starts from scratch and evidence is hard to find.”

A repeatable process for OT assessment and compliance

When control mapping, evidence collection, applicability decisions, findings and reporting are organized consistently, each assessment builds on the last instead of starting again.

Why it matters

Consistency

Different assessors reach comparable conclusions using the same criteria.

Efficiency

Evidence collected once can support several requirements and reviews.

Traceability

Every finding can be traced to a requirement, a control and evidence.

Progress tracking

Results can be compared over time and across sites.

A structured approach

A sequence that can be adapted to your environment and scope.

  1. Select

    Choose the framework and confirm applicable requirements.

  2. Map

    Link requirements to the controls that address them.

  3. Evidence

    Attach or reference evidence for each control.

  4. Find

    Record findings where controls or evidence fall short.

  5. Report

    Summarize status and track corrective actions.

What you end up with

  • An applicability matrix with recorded decisions
  • A control register linked to evidence
  • Findings traceable to requirements
  • A consistent reporting format

Illustrative example

Hypothetical

A company assesses two sites in successive years using different spreadsheets, so the results cannot be compared. A common control set, rating scale and evidence index are introduced. The following year both sites are reassessed in the same structure and progress is visible at a glance.

Frequently asked questions

How should cybersecurity controls be evaluated in industrial environments?

Against an agreed reference, using defined rating criteria, with evidence for each conclusion and an explicit note of operational constraints and compensating measures.

What is an applicability decision?

A recorded judgment on whether a requirement applies to a given system or site, and why. Recording it avoids repeating the debate in every assessment.
