OT network risk in plants: what the standards say
A plant topic we discuss on diagnostic visits — not a Dreamwell service offering.
Quick answer
When machines, PLCs, office PCs and Wi-Fi share one flat network, one infected laptop can reach the line. IEC 62443 and NIST SP 800-82 recommend zones and conduits rolled out in phases. Dreamwell does not sell OT segmentation as a service; we note network layout on a free diagnostic visit and can point you to specialists. Our lead offer is GST billing, inventory, WhatsApp AI and AI ops dashboards.
One infected office PC could stop your line
Flat network
Machines, office PCs, CCTV and Wi-Fi share one network, so one compromised laptop can reach the PLCs.
Vendor remote access everywhere
Machine vendors connect through ad-hoc remote tools that nobody tracks or closes.
Afraid to touch it
Nobody wants to change the network because a mistake could stop the line.

What surveys and standards say
- Standard: IEC 62443-3-2 defines zones and conduits, risk assessment and target security levels before enforcement, and separates safety-related assets — which supports a phased rollout. (IEC webstore, 24 Jun 2020)
- Guidance: NIST SP 800-82r3 and CSWP 28 stress securing OT while protecting performance, including a DMZ between IT and OT. (NIST, 28 Sep 2023)
- Regulation: CERT-In Directions (28 Apr 2022) require reporting attacks on SCADA/OT within 6 hours and keeping logs for 180 days in India. (CERT-In, 28 Apr 2022)

Frequently Asked Questions
Does Dreamwell do OT network segmentation?
No. It is not a Dreamwell service offering. Our lead offer is GST billing, inventory, WhatsApp AI and AI ops dashboards.
What is OT segmentation?
Separating the operational-technology network (machines, PLCs, SCADA, HMIs) from office IT and the internet, so only approved traffic crosses between them.
What do the standards say?
IEC 62443-3-2 and NIST SP 800-82 describe zones and conduits rolled out in phases. CERT-In requires OT/SCADA incidents to be reported within 6 hours.
What does Dreamwell sell today?
