OT Cybersecurity Trends for 2025 | OT After Hours, An OT Security Podcast

Подробнее о видео

In this episode, we delve into the pressing challenges and exciting opportunities in OT cybersecurity as we look toward 2025. Join host Ken Kully, Cyber Tech Lead at Verve Industrial, and his guests Natalie Kalinowski, Tyler Bergman, and Zach Woltjer as they share insights on industry trends, compliance requirements, and the evolving role of AI in securing operational environments.



Key Takeaways:

Hybrid Workforces and Device Risks: Personal and work devices in operational environments pose security risks, requiring stronger BYOD policies.

Regulatory Compliance: Evolving regulations, like NIST and NIS2, drive cybersecurity adoption but lag in addressing sectors like water infrastructure.

AI in Cybersecurity: AI enhances detection, patching, and gap analysis, but foundational security issues must be addressed first.

Dynamic Detection: AI and machine learning are replacing outdated static rules for real-time anomaly detection.

Zero Trust Architecture: The shift to identity- and access-based security is accelerating, especially in hybrid workforce scenarios.

Legacy Device Security: Secure proxies and similar tools help protect aging OT devices, but challenges with latency persist.

Monitoring Approaches: Continuous monitoring offers immediate insights but increases network load, while scheduled checks provide stability but risk delays.

Third-Party Risks: Organizations are diversifying security tools and assessing vendor practices to reduce supply chain vulnerabilities.
