Industrial systems control the physical processes that power factories, utilities, and critical infrastructure. These environments rely on Industrial Automation and Control Systems (IACS) to monitor and control machinery, production lines, and operational processes. Understanding IACS is essential for anyone working in industrial cybersecurity, operational technology (OT), or automation engineering. This guide explains what an IACS is, how it… Read More »

Organizations implementing ISO/IEC 27001 must apply security controls to manage and reduce information security risks. These controls are listed in Annex A of the standard and form a key part of building an effective Information Security Management System (ISMS). Annex A provides a structured set of security controls that organizations can implement based on their risk assessment results.… Read More »

ISO/IEC 27001 is the international standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). The standard helps organizations protect their information assets through a structured framework that manages security risks. It is jointly developed by: ISO/IEC 27001 is widely recognized as the global benchmark for information security management. Purpose of ISO/IEC 27001 The… Read More »

Organizations operating industrial environments often ask an important question: Should we implement IEC 62443 or ISO 27001 for cybersecurity? Both standards are widely recognized in the cybersecurity world, but they serve different purposes. While ISO 27001 focuses on information security management in IT environments, IEC 62443 is specifically designed to secure industrial automation and control systems. Understanding the… Read More »

Industrial control systems are no longer isolated.Modern factories, power plants, water utilities, and oil & gas facilities are increasingly connected to corporate IT networks — and even the internet. With this connectivity comes risk. The global standard created to secure these industrial systems is IEC 62443. In this complete guide, you’ll learn: What Is IEC 62443? IEC 62443… Read More »

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 »
