Cyber Deception Gains Traction as Essential Defense for Operational Technology

The frustrating reality after an OT cyberattack: no data, no trail, and no history. In many Operational Technology environments, security logging is minimal or non-existent, leaving organizations blind after an incident. Cyber deception, traditionally used in IT settings, is being adapted for OT to create a layer of controlled noise. By deploying decoys that mimic critical control systems and fake industrial processes, defenders can detect unauthorized activity early, gather forensic data, and misdirect adversaries. The article emphasizes that deception does not replace traditional OT security measures but serves as a force multiplier for detection and attribution in environments where logging is absent. Security professionals interviewed for the piece note that deception can provide the "history" and "trail" that are otherwise lost when an attack silences SCADA systems or destroys logs. The approach is particularly relevant for legacy OT assets that cannot be patched or monitored with conventional endpoint agents. By interacting with fake human-machine interfaces (HMIs) or emulated PLCs, attackers reveal their techniques, tools, and objectives, providing defenders with actionable intelligence without risking actual operational continuity.
