Frequently asked

Glossary

1

Operational technology (OT)

Hardware and software that monitor or control physical manufacturing processes, including PLCs, HMIs, SCADA and industrial networks. OT security prioritises availability, safety and production continuity, not only data confidentiality.

2

Industrial control systems (ICS)

The combination of sensors, controllers, networks and software used to run plant equipment. ICS security covers protecting these systems from cyber and operational disruption.

3

SCADA

Supervisory control and data acquisition: centralised systems that collect telemetry and send commands to remote plant assets. Securing SCADA often involves network segmentation, monitoring and strict remote-access controls.

4

Programmable logic controller (PLC)

A rugged industrial computer that executes control logic for machinery. PLC hardening includes access control, firmware management and change tracking.

5

Human-machine interface (HMI)

The screen or panel operators use to view and control a process. HMI security covers patching, account control and restricting physical and network access.

6

IT/OT convergence

The linking of enterprise IT networks with plant-floor OT systems for data sharing and remote management. Convergence increases efficiency but expands the attack surface unless segmented and monitored.

7

IEC 62443

The international series of standards for industrial automation and control system security. It defines requirements for operators, system integrators and product vendors, and is a common manufacturing cyber benchmark.

8

Purdue Model

A reference architecture that separates enterprise IT and industrial control zones into levels. Segmentation based on the Purdue Model is a common defence for plant networks.

9

Air gap

Physical isolation of a control network from other networks. Air gaps are increasingly bridged by remote access and removable media, so they need monitoring and policy controls.

10

Zero trust in OT

A security model that verifies users and devices continuously rather than trusting anything inside the plant network. OT zero-trust projects usually start with asset inventory, identity controls and micro-segmentation.

11

OT asset inventory

A continuously updated record of controllers, network devices, software and firmware in the plant. You cannot protect or patch what you have not discovered.

12

Security operations centre (SOC)

The team and tooling that monitor, detect and respond to cyber incidents. A manufacturing SOC needs OT-aware playbooks that protect safety and production continuity.

13

Manufacturing incident response

A prepared process for containing, eradicating and recovering from cyber incidents without unsafe plant shutdowns. It should include manual fallback procedures, backup validation and cross-functional roles.

14

Supply chain cyber risk

The risk that a vendor, integrator or software supplier introduces vulnerabilities into the plant. Manufacturers assess this through questionnaires, contractual controls and connectivity reviews.

15

Secure remote access

Controlled connections that let engineers or vendors support plant equipment without exposing OT networks. Common controls include multi-factor authentication, jump hosts, session recording and time-bound access.

16

NIST Cybersecurity Framework

A voluntary risk-management framework organised around identify, protect, detect, respond and recover. Manufacturers often map OT programmes to it alongside IEC 62443.
