Cybersecurity in Industrial Ethernet

As industries become increasingly connected, the need for robust cybersecurity measures within industrial networks increases. Industrial Ethernet, an essential component of modern automation, not only enables seamless communication but also carries the responsibility of ensuring secure data exchange between interconnected devices. Cyber threats are evolving at a rapid pace, and the vulnerabilities in operational technology (OT) can lead to substantial operational and financial losses. This article explores the key principles of cybersecurity in industrial Ethernet and how RT-Labs’ FSoE product provides an excellent example of security implemented at the foundational level.
