NIST SP 800-82 Rev. 3
Strategic Implementation Checklist
Protect operational continuity
not just IT
NIST SP 800-82 Revision 3 updated guidance for Operational Technology (OT) security to reflect modern convergence, safety constraints and supply-chain realities. Implementing these controls correctly reduces risk to safety, continuity and regulatory exposure while supporting resilient grid and plant operations.
Most OT programs fail not because the controls are unknown, but because they’re applied like IT controls, without regard for deterministic timing, certified safety systems, legacy devices, or vendor maintenance practices. This guide reframes NIST SP 800-82 into a pragmatic, operational playbook for CISOs, OT managers and plant leadership who must protect availability first.
Why this checklist matters now
Electric utilities operate under three non-negotiables: safety, availability, and regulatory accountability. Cyber incidents that impact OT can cause blackouts, safety incidents, regulatory fines, and reputational damage. NIST SP 800-82 Rev.3 translates cybersecurity best practice into OT context-covering governance, segmentation, patching, detection, incident response, and continuity. But the standard alone doesn’t deliver results; you need a sector-aware implementation plan that balances security with operational realities.

This page summarizes a Shieldworkz-first approach to put NIST SP 800-82 Rev. 3 into practice across electric utilities, generation, transmission, and other heavy industrial environments. Download the full guide to get checklists, a 180-day roadmap, and board-ready KPIs.
How to translate NIST controls into safety-aware OT activities (no disruptive scans, no “one-size-fits-all” patches).
A prioritized 30/90/180/365 roadmap for early wins and long-term resilience.
Practical engineering controls (zones/conduits, jump hosts, passive monitoring) paired with human processes (PTW, vendor governance).
Metrics and evidence to brief executives and regulators.
Key takeaways from the Guide
Governance is tactical - Assign a named OT cybersecurity owner and a cross-functional Safety Board that must approve any automated response. Governance reduces hesitation and speeds safe decisions.
Visibility before enforcement - Build passive asset and traffic visibility first. Don’t risk production with active scans; map assets, zones and dependencies before you change airflow or firewalls.
Segmentation that respects operations - Implement zone & conduit controls (Purdue layering) with micro-segmentation where it reduces blast radius without blocking necessary operator flows.
Patch strategically - Use risk-based patching: test in a mirrored environment, schedule within maintenance windows, and apply compensating controls for unpatchable legacy devices.
Human-centric incident response - Create OT playbooks that prioritize safety, include manual fallbacks, and integrate forensic preservation without disrupting control loops.
Measure outcomes that matter - Report asset coverage, detection lead time, and operational recovery time to the board-link security metrics to business resilience.
How Shieldworkz supports your NIST SP 800-82 journey
Shieldworkz pairs deep OT domain experience with pragmatic engineering to reduce implementation risk and accelerate results:
Rapid Passive Discovery: 7-day non-intrusive asset discovery and behavior gap report-no scanning, no downtime.
Risk Workshops & Roadmaps: Joint workshops that convert NIST requirements into a 90-180 day remediation roadmap with owners and budgets.
Safe Segmentation Engineering: Design and validate zone/conduit changes using lab-validated templates before field rollout.
OT-Aware Monitoring & SOC Integration: Deploy OT-protocol parsers, baselining, and tailored alert sets that feed your SOC without overwhelming it.
Playbooks & Tabletop Exercises: Safety-first playbooks and hybrid cyber-physical exercises that rehearse GNSS, power, and control incidents.
Managed Detection & Response for OT: Hybrid MSSP options that keep detection local and escalation operationally aware.
Our approach is technology-agnostic and built to integrate with existing control room workflows-so engineering teams adopt, not resist, security.
