Picture this: an IT security manager receives an alert about unusual network activity on a control system. She escalates it to the network team, who isolates the affected node — a standard IT incident response move. What she doesn’t know is that the node she just cut off was a PLC managing pressure regulation in a chemical process.… Read More »
When a corporate IT server goes down, the worst-case scenario is usually lost productivity and frustrated employees. When an Industrial Control System (ICS) fails — or is compromised — the consequences can be entirely different: a pipeline rupture, a power grid blackout, a water treatment plant releasing unsafe chemicals, or a factory floor accident that injures workers. Yet… Read More »
Industrial Control Systems (ICS) are the backbone of critical infrastructure — from power grids and water treatment plants to manufacturing lines and oil pipelines. As these systems become increasingly connected to corporate networks and the internet, they face growing cybersecurity threats that were once unthinkable in isolated operational environments. This training guide is designed to help all staff… Read More »
The Distributed Network Protocol (DNP3) is engineered to support a broad spectrum of devices in SCADA and automation systems — from simple field instruments and relays to sophisticated substation controllers and data concentrators. To deliver this flexibility without sacrificing interoperability, IEEE Std 1815-2012 defines four implementation levels (L1 through L4). Each level specifies a precise subset of required… Read More »
The Distributed Network Protocol (DNP3) is a widely used SCADA communication protocol designed to enable reliable data exchange between master stations and outstations. It is optimized for transmitting small, structured data packets efficiently and reliably in industrial environments A key strength of DNP3 lies in its object-based data model, which organizes data into object groups, variations, and indices.… Read More »
The Distributed Network Protocol (DNP3) is a widely adopted communication protocol in SCADA (Supervisory Control and Data Acquisition) systems, particularly within electric power and utility industries. Standardized as IEEE 1815, DNP3 was specifically designed to address the challenges of reliable, efficient, and scalable communication over constrained and noisy networks. Its feature set reflects the practical needs of industrial… Read More »
The MITRE ATT&CK framework is one of the most widely used models in cybersecurity for understanding how attackers operate in real-world environments. Unlike traditional security approaches that focus on tools or vulnerabilities, MITRE ATT&CK focuses on adversary behavior—how attackers gain access, move within systems, and achieve their objectives. This makes it an essential framework for: What Is MITRE… Read More »
Industrial cyber security is the discipline of protecting industrial control systems (ICS), SCADA systems, and operational technology (OT) environments from cyber threats that can impact physical processes. Unlike traditional IT security, industrial cyber security focuses on ensuring: As industries adopt digital transformation, Industrial IoT (IIoT), and remote connectivity, the attack surface of industrial systems has expanded significantly. This… Read More »
Industrial Control Systems (ICS) are increasingly targeted by cyberattacks because they control critical infrastructure and physical processes. These attacks often combine IT tools, malware, and industrial knowledge to achieve their objectives. Stuxnet (2010) The Stuxnet attack was a highly sophisticated cyber operation designed to target industrial systems. It spread through infected USB drives, allowing it to bypass air-gapped… Read More »
If you’re searching for ISMS meaning, you’re trying to understand how organizations manage and protect sensitive information in a structured way. ISMS stands for Information Security Management System It is a formal management system used to establish, implement, maintain, and continually improve information security within an organization. The concept of ISMS is defined by ISO/IEC 27001, the international… Read More »
