OT/ICS Security Blueprint For Industrial Operations

Purdue-aligned segmentation, asset visibility, and OT-aware monitoring for manufacturing and utilities.

→INSIDE THE REPORT

Five chapters. One operating reality.

01 · The OT estate as it actually is

Legacy PLCs. Vendor remote access. Engineering laptops with internet. Predictive maintenance pipelines. The OT estate of 2026 is a hybrid IT-OT environment whether or not anyone has acknowledged it.

02 · Asset visibility first

You cannot defend what you cannot see. Passive discovery, traffic-flow mapping and baseline behaviour analysis precede any active control.

03 · Purdue, modernised

Layered defence with documented conduits between layers. Inspection at every conduit. Identity at every conduit.

04 · OT-aware monitoring

OT IDS, signature-and-anomaly hybrid, integration with the IT SOC. The SOC analyst should not need a PhD in industrial control to triage an OT alert.

05 · Operating without breaking production

Change windows, vendor coordination, OT-specific incident response. The blueprint ends with the operating model — because the technology is the easy part.
