Case Study: Building a Zero Trust Architecture to Support an Enterprise

🏙️ Case Study: Smart City Traffic Management

Scenario: A smart city uses IoT-enabled traffic lights and sensors to manage congestion.

Zero Trust Implementation:

  • Device Registration: All traffic sensors are registered and authenticated.
  • Secure Communication: Encrypted channels between sensors and the Traffic Management System (TMS).
  • Access Control: Only authorized systems can send commands to traffic lights.
  • Monitoring: Continuous logging and anomaly detection to prevent tampering.

Outcome: Enhanced security, reduced risk of cyberattacks, and improved traffic flow 

🏭 Example: Industrial IoT in Manufacturing

Challenge: Legacy machines connected to modern networks are vulnerable.

Zero Trust Solution:

  • Micro-Segmentation: Each machine is isolated in its own network zone.
  • Multi-Factor Authentication: Required for remote maintenance access.
  • Behavioral Analytics: Detects unusual machine behavior indicating compromise.

Result: Minimized attack surface and faster incident response
