CSA Advances Zero Trust For Critical Infrastructure
SC Media, Tuesday, November 5th, 2024
The Cloud Security Alliance has released a report recommending a zero-trust approach for operational technology and industrial control systems at critical infrastructure organizations as these entities increasingly become interconnected through the cloud and Industrial Internet of Things technologies
The Cloud Security Alliance has released a report recommending a zero-trust approach for operational technology and industrial control systems at critical infrastructure organizations as these entities increasingly become interconnected through the cloud and Industrial Internet of Things technologies.
The report outlines a five-step strategy for adopting zero trust in these complex environments, starting with asset inventory and risk prioritization, followed by mapping data flows, designing zero-trust architecture, creating restrictive access policies, and maintaining continuous monitoring. It emphasizes the unique challenges of securing older systems now embedded in highly integrated networks, where air-gapped systems are rare. Modernization challenges include handling legacy protocols and adapting systems for real-time monitoring without disrupting operations.
