Written for control engineers, OT security leads and the IT security staff now responsible for a plant

“ICS/OT Incident Response Drills and Exercises”

Make Sure the First Test of Your OT Incident Response Plan Is a Drill, Not the Real Thing

Utilities under NERC CIP-008-6 must test their incident response plan at least once every 15 months. Pipelines under the TSA directives test every year. This book shows you how to run that test on the plant floor and keep a record an auditor can check.

Built on public sources: CISA Tabletop Exercise Packages, NERC CIP-008-6, the TSA Security Directives, and the E-ISAC and SANS analysis of the Ukraine attack

What the Book Stands On

Real incidents and public guidance, not opinion

It retells the December 2015 attack on three Ukrainian power companies: the screens taken over, the backup power cut, the phones flooded, and crews restoring power by hand within hours.

E-ISAC and SANS, March 2016

Follows Norsk Hydro through the 2019 ransomware attack: the network cut, plants switched to manual operation, no ransom paid, and a public briefing every day while it recovered.

Hydro and Microsoft, 2019

The exercise formats draw on the public CISA Tabletop Exercise Packages, and the testing chapters follow what NERC CIP-008-6 and the TSA pipeline directives require you to test.

  • How to build scenarios that escalate in layers, from free CISA exercise packages, across five scenario types
  • Who must be told and by when, and what NERC CIP-008-6 and the TSA directives expect as test evidence
  • How to turn findings into fixes with an after-action report and a tracked improvement plan, and measure progress with a maturity model
  • How to drill a restore on a bench and plan a year of drills around your outages
