Global Critical Infrastructure Survival Manual by Kai London

Resilience is usually written as policy and tested as theatre. This manual is written for the other case: the week when systems are degraded, staff are stretched, suppliers are unreachable and the service still has to run. It sets out what to define in advance, what to practise, and what to do when the plan is only half applicable.

What the book covers

Minimum viable service

Defining the smallest set of functions that must survive, and the dependencies each one actually needs.

Manual and degraded operation

Running without automation, without connectivity or without a key supplier — and the training that makes it feasible.

Isolation and containment

Safe separation of operational systems during an incident, without creating new hazards.

Restoration sequencing

Order of recovery, verification before reconnection, and avoiding reinfection.

People and shift endurance

Rotas, decision fatigue, delegated authority and communication when normal channels fail.

Evidence and reporting

Capturing the record needed for regulators, insurers and post-incident review while the event is under way.

Who it is for

Operations and control-room leaders, OT security and engineering teams, continuity and crisis managers, and executives accountable for essential services.
