This white paper emphasizes the need for unified IT and OT cybersecurity strategies in industrial environments shaped by IoT and Industry 4.0. Traditional security methods like air gapping are no longer effective due to increasing interconnectivity. IT and OT teams must collaborate, sharing context and aligning on frameworks like NIST or IEC 62443. Cisco proposes a phased approach—Identify, Protect, Detect—using tools like Cyber Vision for asset visibility, segmentation, and threat detection. Success requires shared goals, scalable solutions, and cross-functional data to reduce risk, avoid downtime, and ensure secure, uninterrupted industrial operations.
