Challenge Overview

Metro City deployed a comprehensive smart city infrastructure with 10,000+ IoT devices across traffic management, environmental monitoring, and public lighting systems. However, the rapid deployment left significant security gaps:

Critical Vulnerabilities
  • Weak device authentication mechanisms
  • Outdated firmware on 70% of devices
  • No network segmentation for IoT traffic
  • Limited monitoring capabilities
Risk Factors
  • Potential disruption of city services
  • Privacy concerns with citizen data
  • Regulatory compliance gaps
  • High-value target for cyber criminals
