Cybersecurity in industry
Reduce the risk of downtime and prepare for rapid production recovery
OT cybersecurity protects production networks, PLCs, HMIs, industrial computers and other control systems. An effective solution combines restricting unauthorized communication with regular backups of programs and configurations.
Two essential areas of industrial-technology protection
Separate machines and production lines from the corporate network and permit only the devices, services and data flows genuinely required for production.
View firewalls, bridges and NATRegularly store programs, configurations and control-system documentation so that the information required for faster production recovery is ready.

More details: how to get started with OT cybersecurity
Start with an overview of devices, communication and recovery options
Protecting production is not simply a matter of installing one firewall. First, you need to understand the devices in use, network connections, remote access, permitted communication and the availability of current control-system backups.
List PLCs, HMIs, robots, industrial computers, switches and the connections between production, the IT network and the internet.
Separate individual machines, lines and technology units according to their function, importance and risk level.
Permit only essential protocols, services and connections, and remove unnecessarily open communication paths.
Keep current and previous versions of programs and regularly confirm that they can actually be restored.
Industrial networks use specific protocols, devices and operating requirements. The selected solution must suit the production topology, equipment availability and required service method.
Preventive measures cannot eliminate every risk. A current and verified backup reduces recovery time after a fault, an incorrect program change or a security incident.
Frequently asked questions about OT cybersecurity
IT security primarily protects information systems and corporate data. OT security focuses on devices and communication that directly control physical production.
Not always. It depends on the current topology, IP addresses, protocols used and the way devices communicate with higher-level systems.
A basic network topology, a list of critical devices, information about remote access and a description of the current PLC and machine backup process are sufficient.
How to Meet NIS2 Requirements: Secure Remote Access with Ewon Routers and W&T Firewalls
The European NIS2 directive introduces new obligations for companies in protecting against cyber threats. Below, we compare these requirements with the technical measures in IEC 62443 and show how to meet them easily using Ewon industrial routers, the secure Talk2M cloud service, and firewalls from the German manufacturer W&T.
