Vincent,

IoT does play an important role in traditional SCADA networks and will bring even more value in future years. Think of SCADA as just another data source for your IoT environment which will also digest data from CRMs, Customer Reporting engines, Customer/Employee facing Mobile apps, etc. Edge or Fog processing will certainly play a big role as more control capabilities are required/deployed and those will need to be secured in the same manner that we secure IP networks today (defense in depth). Cisco has a complete security architecture that addresses every aspect from end-point, to edge to the DC (private or public).
