Safeguarding Industrial IoT Networks with IT/OT Security - Lanner Electronics | Network Appliance | uCPE SD-WAN| MEC Server | Intelligent Edge Appliance

The risk of cyber threats in the Industrial IoT networks has escalated in a historical pace as IIoT applications, like smart factory, intelligent transportation and smart grid are connected by mainstream network protocols. The malicious attacks have evolved to be even more destructive than ever, namely Stuxnet worms, DDoS attacks, ransomware, Trojan and other breaching methods and these can penetrate into IIoT networks from multiple paths on both the IT (Information Technologies) and OT (Operating Technologies) network infrastructure.

To fully protect IIoT converged networks from advanced cyber malwares, it is necessary to establish multi-layer protections covering both IT and OT networks, including:

Industrial Zone (Layer 0~3)

The instrumentation bus, controller LAN and supervisory HMI and SCADA systems

Industrial DMZ Zone (Layer 3.5)

The data exchange network layer includes mail server, application servers

Enterprise Zone (Layer 4~5)

The enterprise network layer contains web server, email server, FTP server and enterprise servers

Lanner, the leading hardware solution providers for network security, offers wide-range, customizable hardware platforms designed to protect the communication protocols in both IT and OT domains. Our IIoT security platforms cover the rugged industrial firewall in OT networks, as well as rackmount network security appliances deployed as UTM, internal segmentation firewall and next-gen firewall in IT networks.
