18 DVI-100 Digital Voice Interface The Voice-Bridge (Smart-ISI)

19 The DVI-100 (Digital Voice Interface) is a special TETRA terminal, that feeds all received TETRA voice signals to its Ethernet (IP) port and vice verse, without any conversion to analog. So there is no reduction of the original TETRA voice quality. Additional also Status and SDS messages are forwarded to the DVI Ethernet port and sent to a (any) destination IP (and vice verse). The DVI uses the Open PTX Protocol ( developed in co operation by the University of Dortmund and Piciorgros GmbH

23 The DVI-100 can be operated in DMO Mode and can be used as a TETRA Micro-Spot: Connected to a DVI-Server Connected to a PC / iphone / ipad Connected to a TETRA Infrastructure switch

25 The DVI-100 Features Connect TETRA networks of different manufacturer Connect TETRA networks with different frequencies (450 MHz / 800 MHz) In house coverage Access to the own TETRA network from out of the coverage area (Paris Cologne) Temporary Micro-Spot (on site) Dispatcher Design your own application

26 SCADA, Telemetry and Telecontrol using TETRA Infrastructure

27 Typical SCADA Server Layout Ref: Scada: Wikipedia Monitor: Samsung

28 TETRA Modem - TMO-100 with two serial Ports, one Ethernet Port and an Audio Port

29 TETRA Modem - TMO-100 as before with additional embedded I/O

42 Potential IP Risks (Back Doors) Control Room Air Interface Remote Modem

43 Risks using IP Communication via wireless Infrastructures to Remote Outstations SCADA Control Room PD TMO-100 IP Remote Modem Control Room PD Router / Gateway PD TMO-100 I/O Command and Control Line Device Tetra Switch Air Interface TMO-100 IP AMR, PLC or RTU

44 Potential IP Risks (Hacks) Access from the SwMi side to the remote modems (RTU s) Hacker send Control and Command data to the remote RTU s Access from the remote devices to the SCADA Server (Intranet) Hacker try to access and stress the Intranet, SCADA Server or any other Intranet Server Access via the Air Interface (using a spare TMO-100) Hacker try to access the Intranet or try to send commands to the Outstation RTU s IP Data flooding via a remote device Hacker try to flood and stress the TETRA Infrastructure with data packets Using IP Services to access the Intranet via a Remote Modem Hacker try to use services (ports) like Telnet, FTP or others to access and stress the Intranet

45 TMO-100 Protection and Firewall(s) Access from the SwMi side to the remote modems (RTU s) The IP Server Source Address received by the TMO-100 can be restricted to a specific IP Address or a specific IP Address range Access from the remote devices to the SCADA Server (Intranet) The RTU Source Address received by the TMO-100 can be restricted to a specific IP Address or a specific IP Address range Access via the Air Interface (using a spare TMO-100) Enable AIE to avoid unwanted Access via the Air Interface IP Data flooding via a remote device A configurable IP Flooding Filter stops the data flow for a specific time (5 minutes), after the TMO-100 has received a specific number of IP Packets (5 packets) in a specific time frame (10 seconds) Using IP Services to access the Intranet via a Remote Modem Optional all IP ports can be disabled while up to 5 can be enabled individually

46 Conlusion: The TETRA Performance is sufficient for the most SCADA Applications TETRA can do Serial and IP Communication With TETRA as a PMR Network, the user has full control of his Infrastructure (Power Supply, Antennas, Back Bone, ) TETRA is the savest (ref.: Public Safety) existing wireless network Existing Technologies to protect against Cyber Criminals TETRA will be available at least for the next Years
