Securing Smart Cities: Protecting Connected Urban Infrastructure

The Rise of Smart Cities

Smart cities leverage IoT sensors, connected infrastructure, and data analytics to improve efficiency, sustainability, and quality of life. However, this increasing connectivity also expands the attack surface for cyber threats.

Key Vulnerabilities

Smart city deployments face several critical security challenges:

Highly Connected Infrastructure

Traffic systems, power management, public safety networks, and other vital services are increasingly interconnected, creating potential cascading failure points if compromised.

Legacy System Integration

Many smart city initiatives must integrate with decades-old infrastructure that was never designed with cybersecurity in mind.

Protection Approach

Securing smart city infrastructure requires a multi-layered strategy:

Network Segmentation and Isolation

Implementing hardware-based isolation between critical systems ensures that compromise of one component cannot affect others.
