Description

A focused course, tailored for you

The OT Security Assessment Delivery Playbook

For OT cybersecurity practitioners: build the IEC 62443 assessment, risk register, and client roadmap from a live industrial engagement.

The corrected Zone and Conduit model is done, the SL-2 gap register has 47 findings, and the client plant manager wants to know which ones require a planned maintenance window to fix. That question is where the technical assessment stops and the consulting delivery begins, and it is the question most OT security practitioners get wrong in front of the client.

Why this course

OT cybersecurity practitioners with strong technical backgrounds can run the asset walk, identify the IEC 62443 gaps, and enumerate the NERC CIP non-compliances. The part that stalls the engagement is translating those findings into client artefacts that two different audiences, plant engineering and the CISO, accept without rejecting each other's priorities. The risk register reads as a technical document. The roadmap ignores production constraints. The executive summary loses the technical credibility. The engagement closes without a path to the next one. This course addresses that specific delivery gap: not the OT technical knowledge, but the consulting delivery methodology that converts technical findings into artefacts an industrial client actually pays for.

What you walk away with

Build a passive OT asset discovery methodology that generates a defensible asset inventory without disrupting production.
Construct an IEC 62443 Zone and Conduit model from the corrected as-built topology and assign Security Level targets by zone.
Produce an OT risk register that plant managers and CISOs accept without conflicting edits.
Build a remediation roadmap phased around planned maintenance windows, not IT patch cycles.
Write an OT incident response playbook as a client deliverable alongside the assessment.
Close the assessment engagement in a way that surfaces the next engagement naturally.

The 12 modules

Module 1. OT Asset Discovery in Production Environments

A live industrial plant cannot be scanned the way an IT network can. This module builds the passive discovery methodology: traffic mirroring from industrial switches, manual asset walk protocols with plant operators, historian queries for device-to-device communication patterns, and the reconciliation process for converting discovery outputs into an asset inventory that passes plant engineering review.

Module 2. The Purdue Model Reality Check

The Purdue model diagram in pre-engagement documentation is almost never current. This module teaches how to map actual Level 0-3 topology from passive observation, identify Level 3-to-DMZ bridging that bypasses the IDMZ, and produce a corrected architecture diagram that becomes the foundation of the IEC 62443 Zone and Conduit model. Template for the corrected topology diagram included.

Module 3. IEC 62443 Zone and Conduit Model Construction

Converting the corrected topology into an IEC 62443-compliant Zone and Conduit model. This module covers zone boundary decision criteria, conduit communication flow documentation, the Security Level target assignment process for each zone, and the structured format for presenting Zone and Conduit diagrams to both plant engineering and the client CISO so both audiences accept the scope without revision.

Module 4. IEC 62443 SL Gap Analysis and Gap Register

Mapping each zone against its Security Level target using IEC 62443-3-3 system requirements. This module covers the structured gap-finding process for SL-1 through SL-3, how to document control gaps without relying on scanning-based findings in air-gapped or semi-air-gapped zones, and the gap register format that feeds directly into the client remediation roadmap.

Module 5. NERC CIP Controls Mapped to Industrial Asset Classes

For clients in the energy sector, gap findings need a NERC CIP crosswalk. This module maps NERC CIP-002 through CIP-014 requirements to the industrial asset classes found in generation and transmission environments, covers what qualifies as a Critical Cyber Asset, and produces the crosswalk table the utility compliance team uses to prioritise remediation against both frameworks simultaneously.

Module 6. Assessing OT Vendor Remote Access and Third-Party Risk

OEM vendor maintenance sessions are the most common uncontrolled access vector in industrial environments. This module covers how to assess remote access architecture for vendor sessions, identify credential-sharing and jump-host weaknesses, document findings in the OT risk register, and recommend controls that do not violate OEM support agreements or maintenance contractual obligations.

Module 7. OT Vulnerability Assessment Without Live Scanning

Running an active scanner against a live industrial controller is a production incident. This module covers passive vulnerability identification from firmware version enumeration, configuration review, vendor advisories, and ICS-CERT bulletins, and teaches how to build a credible vulnerability exposure section in the assessment report without generating scan traffic toward active control systems.

Module 8. The OT Risk Register for Executive Review

Technical findings need to be restated as business risk before the CISO signs off. This module covers translating ICS security gaps into consequence scenarios including production downtime, safety system bypass, and environmental release, quantifying likelihood against the client's threat profile, and structuring the OT risk register as a document both the plant manager and CISO can accept without conflicting edits.

Module 9. Building the Remediation Roadmap with Production-Safe Phasing

An OT remediation roadmap that ignores maintenance windows will be rejected by the plant. This module covers identifying planned downtime windows from CMMS schedules, sequencing remediations into pre-maintenance, during-maintenance, and online-safe categories, assigning remediation ownership across IT, OT, and OEM teams, and producing the phased roadmap in the format clients use for ongoing delivery tracking.

Module 10. Writing the OT Assessment Report for Two Audiences

The technical findings appendix and the executive summary are different documents with different vocabularies. This module covers the structure for a dual-audience OT security assessment report: technical findings appendix with IEC 62443 clause references, executive summary with consequence framing, and the management action plan that ties gap priority to roadmap phase. Report templates for all three sections are included.

Module 11. OT Incident Response Playbooks for Industrial Environments

Shutting down an infected workstation is not the right response when that workstation is the HMI for a production line or a substation RTU. This module covers OT-specific incident response decision trees, the IT and OT coordination protocol for a live ICS event, containment options that preserve production where possible, and the format for the OT IR playbook delivered as a client artefact alongside the assessment.

Module 12. Packaging the OT Assessment as a Repeatable Engagement

A one-off assessment has no delivery leverage. This module covers how to structure the assessment deliverables as a reusable delivery kit, how to scope follow-on engagement opportunities from the findings, and how to present the completed package in the close-out meeting in a way that surfaces the next engagement naturally without a separate sales conversation.

How this addresses your situation

Specific modules that map to what you said you are dealing with.

Working on a brownfield industrial site where nobody has the current as-built network diagram: start with Module 2 (Purdue Reality Check) then Module 1 (Asset Discovery Methodology).

Client is a utility asking how findings map to NERC CIP alongside IEC 62443: Module 5 (NERC CIP Crosswalk) runs in parallel with Module 4 (SL Gap Analysis).

Plant manager is pushing back on the remediation roadmap because it ignores scheduled outage windows: Module 9 (Production-Safe Phasing) with the CMMS-aligned sequencing template.

Client CISO wants a board-ready risk summary but plant manager wants technical clause references: Module 10 (Dual-Audience Report Structure) and the management action plan format.

Before and after

Before

Assessment findings are technically accurate but delivered as a gap list the client struggles to prioritize. The plant manager and CISO want different things from the report. The engagement closes without a path to follow-on work.

After

Every OT security engagement produces a Zone and Conduit model, SL gap register, production-safe roadmap, and executive risk register that both audiences accept. The close-out meeting surfaces the next engagement naturally.

What happens if you do not address this

OT security assessments that do not translate findings into client-ready artefacts lose the engagement at the review stage. The plant manager rejects the roadmap because it ignores production constraints. The CISO cannot action the risk register because it reads as a technical document. The follow-on engagement does not materialise. Technical credibility without delivery methodology is where consulting assignments stall.

Who it is for

OT cybersecurity practitioners with 3-10 years of industrial systems experience, including ICS vendor background, plant-side engineering, or utility operations, who are now delivering security assessments for consulting clients. They understand Purdue model topology, IEC 62443 structure, and what a PLC's network traffic looks like. The gap they are filling is structured consulting delivery: how to produce the Zone and Conduit model, SL gap register, OT risk register, and remediation roadmap in formats that close the engagement and open the next one.

Who this is NOT for. IT security practitioners rebranding as OT consultants without hands-on industrial systems experience. This course assumes you already understand ICS and SCADA architecture, Purdue model segmentation, and the operational constraints that distinguish OT from IT security. It teaches consulting delivery methodology, not OT fundamentals.

How it arrives

Text-based course in the Art of Service learning environment, plus downloadable templates and worked examples for every module, plus the hand-built implementation playbook delivered alongside course access.

Time investment. Each module is designed to complete in 45-90 minutes. The full course is structured for delivery over 2-3 weeks alongside active client work, with each module aligning to a phase of a live OT assessment engagement.

Why $199 is the right number

Self-study through IEC 62443 standard documents and ICS security curriculum covers the technical knowledge but not the consulting delivery structure. Internal firm training covers methodology but not OT-specific artefact construction for dual audiences. This course fills the gap between deep OT technical knowledge and client-facing delivery methodology that closes engagements and opens the next one.

FAQ

I already understand IEC 62443. Does this course cover anything I don't know?

The course assumes IEC 62443 knowledge. It teaches the delivery methodology for converting that knowledge into client artefacts, Zone and Conduit models, SL gap registers, OT risk registers, and remediation roadmaps, in formats that both plant engineering and CISO audiences accept. If you know the standard but have had clients reject the roadmap or the risk register, that is the gap this course addresses.

Does this course cover NERC CIP?

Module 5 covers NERC CIP-002 through CIP-014 mapped to industrial asset classes, the Critical Cyber Asset qualification process, and the crosswalk table format for clients who need both IEC 62443 and NERC CIP alignment simultaneously.

How is this different from a standard cybersecurity consulting course?

Every module is built around OT-specific delivery constraints: passive discovery instead of active scanning, maintenance window phasing instead of IT patch cycles, dual-audience reporting for plant engineering and executive audiences simultaneously. Generic cybersecurity consulting methodology does not account for these constraints.
