DESCRIPTION:How do you know the communication your production depends on i
 s actually secure?\nCommunication is everywhere in manufacturing. Controll
 ers\, applications\, machines and systems constantly talk to each other\, 
 but the protocols behind that communication usually do not get much attent
 ion. If production keeps running\, then everything is fine. Until somethin
 g goes wrong and protocol vulnerabilities turn into real availability and 
 safety problems like an explosion.\nI wanted to look a little deeper into 
 industrial communication\, so I studied a real manufacturing environment a
 nd analysed how common protocols like Modbus TCP\, OPC DA\, OPC UA and MQT
 T were configured and used in production.\nIn this talk\, I will share the
  most interesting findings\, explain why they matter in practice and discu
 ss ways to improve communication security based on IEC 62443. My goal is t
 o help you look at communication in your own OT environment from a differe
 nt perspective and maybe start asking questions you had not thought to ask
  before.\n\nThird-party version:\nHow do you know the communication your p
 roduction depends on is actually secure?\nCommunication is everywhere in m
 anufacturing. Controllers\, applications\, machines and systems constantly

 ed to look a little deeper into industrial communication\, so they studied

 odbus TCP\, OPC DA\, OPC UA and MQTT were configured and used in productio
 n.\nIn this talk\, the speaker will share the most interesting findings\, 
 explain why they matter in practice and discuss ways to improve communicat
 ion security based on IEC 62443. The speaker’s goal is to help you look 
 at communication in your own OT environment from a different perspective a
 nd maybe start asking questions you had not thought to ask before.
