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.
Real and intense financial pressures on rural and small healthcare clinics mandate making difficult decisions on allocating funds to cybersecurity, said Greg Sieg, CISO at the University of Michigan Regional Health Network. "The funding is just not there."
Attorneys can conduct security risks assessments under the color of client privilege, making it less likely to surface in discovery during litigation. But healthcare firms should consider the cons before they take that route, said attorney Adam Greene, partner at the law firm Davis Wright Tremaine.
Segmentation Mandates Make One-Way Data-Flow Architectures EssentialData diodes are re-emerging as a preferred control as IT-OT convergence expands the industrial attack surface and regulators tighten segmentation mandates. Hardware-enforced, one-way data flow offers provable isolation for critical infrastructure and growing executive accountability.
Rural hospitals and clinics continue to struggle with a lack of cyber resources but a federal grant program set to provide $50 billion worth of funding across all 50 states could hopefully help lessen some of the pain, said Jim Roeder, VP of IT at Lakewood Health System in Minnesota.
Long-life medical devices - products typically used for a decade or longer - are among the most post-quantum, cryptographically vulnerable technologies in healthcare, said Joern Lubadel, global head of product security at German-based medical device and healthcare products maker B. Braun.
For the U.S. healthcare ecosystem, the 2024 ransomware attack on Change Healthcare proved to be a supply-chain earthquake in showcasing critical third-party risk that entities now must carefully and urgently consider, said Erik Decker, CISO of Intermountain Health and a federal cyber adviser.
Medical device cyber challenges are among the most complex for manufacturers and healthcare delivery organizations for a variety of reasons, but there are some promising developments underway that could help ease the pain, said Phil Englert of the Health Information Sharing and Analysis Center.
Healthcare Hit Shows Symbols Matter as Iran Shifts Focus to Economic DamageCybersecurity experts say that the Handala "hacktivist" group that claimed credit for attacks against two American firms on Wednesday is run by the Iranian government. The shift to destructive cyberattacks parallels Iran's attempt to inflict greater economic damage on the United States and allies.
Many healthcare sector organizations are delaying to even begin contemplating - let alone strategizing - how to mitigate post-quantum risk - but procrastination is a major mistake, said Ali Youssef, director of emerging tech security, at Henry Ford Health.
What often appears to be turf wars between healthcare technology management, facilities OT staff, IT departments and security teams are often the result of unclear ownership and accountability for device security. And that presents safety risks to patients, says Mohammed Waqas, CTO of Armis.
Healthcare CISOs and their teams often contemplate the benefits of going passwordless in their organizations but face pushback from clinicians concerned that the new tech will slow down their access to critical patient care systems or disrupt their workflow.
CS4CA USA Summit Speaker Daryl Haegley on Zero Trust and OT VisibilityCritical infrastructure operators face constant cyber probing from state adversaries targeting energy, water and industrial systems. A U.S. Air Force cyber resiliency leader explains why zero trust, IT-OT separation and stronger anomaly detection are essential to defend mission-critical operations.
