xOT Cybersecurity Fundamentals
Summary: Dragos describes xOT as covering the full operational technology environment, meaning every system that influences a physical process, and says the SANS ICS 5 Critical Controls framework covers OT-specific incident response, defensible architecture, ICS network visibility and monitoring, secure remote access, and risk-based vulnerability management. The text states basic OT visibility and monitoring can be established in 30-90 days depending on network complexity, while full implementation of the SANS ICS 5 Critical Controls can take 2-18 months.
Bottom line: The source warns that standard IT tools can disrupt operations directly: vulnerability scanners can fault PLCs and network monitoring tools can flood industrial networks, and patches often require costly production shutdowns. With full implementation of the five controls taking 2-18 months, the gap between where an OT environment sits today and where the framework says it should be is measured in production risk, not just project schedule.
