At the recent Black Hat security conference some researchers presented vulnerabilities to access control systems that enabled them to remotely lock and unlock doors just like you see in the movies, and even blocked the access from being logged.
Separately, as part of a wider cyber attack on RuTube, Russia’s competitor to YouTube, employee access cards were blocked locking people in server rooms.
Access control systems are just one of several operational technology (OT) systems in buildings that are vulnerable to cyber attacks. Other OT systems include HVAC, lighting, elevators, electrical and energy management. There is growing commentary around providing a zero trust framework to protect OT networks, and Veridify Security uses this approach with our DOME cybersecurity solution for OT networks and building systems.
