OT & Critical Infrastructure Resilience All-in-One by Kai London

Essential services cannot simply be paused while IT recovers. This book is about continuity where the consequence is physical — keeping the process safe and supply flowing when the control room loses its screens, and proving to a regulator that you can.

Available on Amazon.

What is inside

Control room continuity

Operating with degraded or absent visibility, and the alternate arrangements that keep decisions safe.

Manual operations

Documented procedures, trained people and the honest limit on how long manual running is sustainable.

Safety under disruption

Keeping safety functions independent and verified when everything above them is unreliable.

Designing for degraded modes

Architecture and engineering choices that create a survivable middle ground between running and stopped.

Restoration and validation

Bringing control systems back in a verified order, with integrity checks before the process is handed back.

Exercising and evidence

Testing with operators and engineers, capturing the findings, and evidencing capability to regulators.

Who it is for: control room and operations leadership, OT security and engineering teams, continuity planners in essential services, and infrastructure boards and regulators.

When the screens go dark, the process does not stop being your responsibility.
