Background for this topic.
Critical infrastructure includes systems and assets vital for public health, safety, and economic stability, such as power grids, water treatment, transportation networks, and healthcare facilities. These systems often combine physical components with industrial control systems (ICS) and operational technology (OT) that manage essential services in real time.
From an information-security perspective, critical infrastructure faces risks like unauthorized access to control systems, disruption of service availability, and manipulation of sensor data. Defending these assets requires specialized security measures tailored to ICS environments, including network segmentation, strict access controls, and continuous monitoring for anomalies. Ensuring resilience also involves coordinated efforts between operators and government agencies to address vulnerabilities unique to legacy systems and proprietary protocols.
Attacks on critical infrastructure are ramping up — but organizations now have the knowledge and tools needed to defend against them.
Following the Volt Typhoon attacks on critical infrastructure in the region by China, the US reportedly will share cybersecurity threat information with both countries.
RansomHub, which is speculated to have some connection to ALPHV, has stolen 4TB of sensitive data from the beleaguered healthcare company.
