Network segmentation is one of the most important cybersecurity principles in modern SCADA and industrial control systems. It is not just a best practice. In the IEC 62443 series of standards, segmentation is a core security requirement. In simple words, network segmentation means: Do not allow every device to talk to every other device. Instead, divide the system… Read More »
IACS Cybersecurity focuses on protecting Industrial Automation and Control Systems (IACS) such as SCADA, PLCs, RTUs, DCS, IEDs, and industrial networks from cyber threats while ensuring safety, availability, and operational reliability. For operators of critical infrastructure—power utilities, oil and gas, manufacturing, water, and renewable energy—cybersecurity is no longer optional. Modern industrial systems are connected, remote-access enabled, and increasingly… Read More »
Modern industrial networks depend heavily on remote communication. Whether it is a control center talking to a substation, a SCADA system collecting data from a water pump, or a utility monitoring dozens of remote field stations, the network path between these locations must be reliable, secure, and predictable. Two common technologies are used today to connect a central… Read More »
