Fremont, California (EastBayDaily) — Built upon Industry 4.0, the essence of smart factory lies in a well-connected communication network which allows for automated manufacturing, remote production monitoring, and smooth operations. The communication network as a key role for smart factories helps integrate data from sensors and manufacturing equipment, making it possible to apply big data analysis to optimize production, logistic, and inventory management. To help fortify online security for industrial appliances, NEXCOM has released a whole new product line, the HENGEâ¢ industrial firewall series.
“Factory owners must build a smart factory step by step” said Hadwin Liu, Chief Architect of NEXCOM Network and Communication Solutions Business Unit. “Establishing efficient and secure industrial communication architecture is critical.”
Flexible Industrial Communications Meet Demands
The circuit switching method, commonly used in traditional industrial communication architecture, has several drawbacks. The connection holds a physical link and has dedicated bandwidth which cannot be shared and leads to poor transmission efficiency. The maintenance is complicated and time-consuming. Industrial Ethernet, on the other hand, adopts packet switching method which uses virtual circuit, supports full duplex operation, allows bandwidth to be shared among nodes, and supports traffic prioritization. The installation and maintenance is also simpler.
Enhanced Network Security with VPN and Industry Firewall
“Cyber attacks are inevitable as long as companies rely on internet connection. Virtual private network (VPN) and industrial firewalls must be deployed for network security,” Liu reminds. “Industrial firewalls are used to protect assets. VPNs are encrypted tunnels that protect messages from eavesdropping or tampering, which secure remote access.”
Despite of high availability of commercial VPNs and firewalls, their protection level and durability are different from industrial ones. Industrial firewalls, such as NEXCOM’s HENGEâ¢ series, feature stateful inspection firewall technology to allow only authorized packets to pass. Also, industrial firewalls support industrial protocols for deep packet inspection. With extended temperature support design, industry firewalls are highly reliable under harsh operating environments. With multiple years cultivating in industrial communication, NEXCOM’s industrial HENGEâ¢ VPNs and Firewalls pave the way for factories’ IP migration.
