Zero Trust: Reinforcing Security in Industrial Control Systems
As industrial control systems (ICS) become increasingly digitized, ensuring robust ICS security measures is paramount. In this article, we delve into the concept of Zero Trust and its potential to revolutionize the security landscape for industrial control systems. With cyber threats evolving in complexity and sophistication, traditional security measures are no longer sufficient. Zero Trust…

Heat and Hot Water Disrupted to over 600 buildings, about 100,000 people, for 48 Hours Cyberattack on a Heating Utility A cyberattack on a heating utility (also known as district heating) in the Ukrainian city of Lviv, the largest city in western Ukraine, in January 2024. The malware, named FrostyGoop, is one of the few…
Read MoreDNP3 Cybersecurity Risks: How to Protect ICS & SCADA Systems
DNP3 Cybersecurity Risks Quick Summary DNP3 is widely used in ICS and SCADA but faces significant security gaps, especially in legacy systems. Common threats include man-in-the-middle attacks, packet manipulation, and master impersonation. Legacy compatibility issues mean many systems still lack encryption and authentication. Mitigation requires strong authentication, encryption, integrity protection, and network segmentation. Zero Trust…

Read MoreZero Trust – A Virtual Air Gap for OT Security
Air-gapping computer and operational technology (OT) networks is a long-established method of protecting sensitive information and reducing the risk of operational disruption. A growing trend has been to provide connectivity from these networks to the Internet for remote monitoring and control, real-time data, data analysis, predictive maintenance, improving inventory and resource management, achieving faster decision-making,…
Read MoreModbus Security Issues and How to Mitigate Cyber Risks
Key Points Modbus Lacks Fundamental Security: Designed for isolated environments, Modbus protocols (especially Modbus TCP) lack encryption, authentication, access control, and integrity checks, making them highly vulnerable to cyberattacks. Common Vulnerabilities: Issues include default configurations, outdated firmware, absence of logging, susceptibility to replay, MitM, DoS, command injection, insider threats, and poor physical and network security.…
