Threat intelligence for operational technology environments differs from traditional IT threat intelligence. OT threat intelligence requires contextual, situational awareness that identifies vulnerabilities and anomalies, and also which assets, and in what part of the process, are exposed. It must also note what the safety and operational consequences would be if exploited. This context enables security teams to prioritize risk mitigation according to real-world impact rather than theoretical severity.

A diversified operational technology (OT) cybersecurity monitoring platform plays a key role in strengthening the protection of cyber-physical systems by providing clear visibility, real-time threat detection, and proactive risk mitigation. By integrating multiple monitoring tools and technologies, organizations can build a layered security approach that minimizes vulnerabilities, improves response times, and keeps critical systems resilient against cyber threats.

Mike Ratliff, CISO at Providence, one of the country's largest not-for-profit healthcare providers, writes about his organization's attempt to re-think GRC as Governance, Risk, Attack Surface Management, and Compliance (GRAC). Ratliff describes five areas GRAC improves the overall security program, including the quantification and prioritization of risk, the integration of attack surface management, and an architecture that supports secure-by-design principles.

The HHS Office for Civil Rights proposes substantial rule changes to the long-standing Health Insurance Portability and Accountability Act (HIPAA) Security Rule. While details on the proposed rule changes remain unclear, HHS plans to issue a Notice of Proposed Rulemaking (NPRM) by the end of the year. These changes are believed to be the most substantial changes since the HIPAA Security rule went into effect in 2003

In this episode of the Nexus Podcast, Pedro Umbelino, Principal Research Scientist at Bitsight Technologies, joins to discuss his team's research into Automatic Tank Gauge (ATG) systems and how they uncovered 11 vulnerabilities in ATGs manufactured by five different vendors. ATG devices have sets of sensors that measure and record fuel levels, condensation, temperature, and volume in storage tanks. They are critical because they can be used to monitor for leaks, and can trigger alerts, sirens, perform emergency shutoff procedures, or allow for ventilation if necessary.
