The Restart Bottleneck Is Not the Backup. It Is the Evidence.

What this episode examines

After an OT cyber incident, restoring systems is only the visible part of recovery. The harder question comes next: who can prove that production is safe to restart?

In this episode of Cybersecurity Under Pressure: real attacks, real lessons, we look at why OT recovery is different from IT recovery. A backup may exist. The PLC logic may appear unchanged. The virtual machine may boot. But in automotive and high-cadence manufacturing, restarting without trusted evidence can create a second crisis.

We discuss engineering workstations, SCADA-related Windows servers, virtualised OT environments, dwell-time assessed baselines, out-of-band evidence, tamper-evident logs and pre-agreed IT/OT go/no-go criteria.

The real challenge is not only technical recovery. It is building enough operational confidence for plant management, cybersecurity, quality and product safety to make a defensible restart decision under pressure.

Because in OT, the strongest recovery teams are not the ones with the longest backup catalogue. They are the ones that can answer one question with evidence:

Why is it safe to restart now?
