Connect and protect building a trust based internet of things for business critical apps

  2. 2. 2#ATM16 • The Internet of Things (IoT) is comprised of stationary and mobile devices used to harness the world around us • Mining device data enriches decision making to a degree no one device could facilitate on its own • Only trusted devices and data with verified integrity should be leveraged to make decisions • Today’s IoT isn’t trustworthy: it’s a riddle of PHYs, wrapped in an enigma of protocols, protected by a hairball of security
  3. 3. 3#ATM16 The Internet of Untrusted Things • Devices built for speed and reliability may have little, no, or outdated security • Many lack access rules, key mgmt, zero day attack prevention, authentication, anti-malware, encryption, firewalls
  4. 4. 4#ATM16 Legacy Trust • Operational efficiency focuses on process and performance • Trust equals physical control of devices and is rarely reassessed • Changes in technology have created security gaps • The fix: establish logical control of data & devices

  8. 8. 8#ATM16 Applying Red-Black Trust Paradigm Untrusted Point Of Demarcation Trusted • Red is untrusted, black is trusted, point of demarcation is ideally at the data source • Most IoT devices lack security and it isn’t economically feasible to replace them • Objective is to move the point of demarcation as close as possible to the data
  9. 9. 9#ATM16 Demarcation Varies By Device Type Tools for business intelligence and threat monitoring Smart devices may be demarcation points if they have sufficient processing power and memory Demarcation points for less capable devices lower in pyramid Visualization, reporting, compliance Common demarcation points Stationary Machines & Controllers Mobile Machines & Controllers Smart Sensors & Actuators Microprocessors & Microcontrollers HMIs Analytics
  10. 10. 10#ATM16 Connect-and-Protect • Establishes trustworthy data sources for business intelligence and decision making • Eight steps to trust 1. Make a physical layer (PHY) connection 2. Talk the talk with existing device protocols 3. Establish authenticity of devices and users 4. Encrypt the data 5. Secure communication pathways 6. Establish and enforce device and user roles 7.
