About Session

Technical Level: Intermediate

Have you ever been on an Internet safari? Join us on an expedition into the world of internet-connected OT-devices!
We’ll introduce you to our OT Big Five and share fascinating cases we have encountered. We’ll also explore the motivations behind our research, how the NCSC identifies OT-devices at scale using repeatable methods, and the legal and technical aspects involved. You’ll walk away with new insights on the vast number of OT-species out there, and why we believe they should migrate away from the internet. Are you ready to join the expedition?
