For many years all BMS protocols were installed without cybersecurity. The only activity focusing on security was access control and hotel room control.

Today with the large number of BMS systems deployed, the security on existing installations is introduced in mind. For new projects cybersecurity is requested in sensitive installations, but 90% of the installations use one or many protocols such as LonWorks, KNX, BACnet or Modbus without cybersecurity for more than 10 or 20 years.
