Challenge

Deploying smart, connected corridors, autonomous traffic controls, and vehicle-to-everything (V2X) systems drastically expands municipal attack surfaces, creating critical vulnerabilities across transportation networks.

​

Navigating the Modern Attack Surface
 

  • AI-Driven Exploits
    Over 16% of breaches now leverage AI to automate social engineering and accelerate the exploitation of legacy IT/OT systems(1).
     

  • IT/OT Convergence
    Merging operational and digital networks can expose critical systems to threats such as V2X spoofing, EV grid manipulation, and sensor tampering.
     

  • Pervasive Blind Spots
    Gaps in OT asset visibility can make it difficult for operators to identify connected OT hardware, track firmware compliance, and enforce network micro-segmentation.

Cisco Solution

The unified Cisco + Splunk architecture bridges IT and OT security, directly mitigating the primary cyber-risks facing modern roadway networks.
 

  • Zero-Trust Network Segmentation
    Enforces automated micro-segmentation across connected field assets, isolating localized breaches to prevent network-wide traffic or power disruptions.
     

  • Continuous OT Visibility and Compliance
    Uses edge-level deep packet inspection through Cisco Cyber Vision to continuously identify assets, monitor firmware health, and enforce policy compliance.
     

  • Unified Intelligence and Automated Remediation
    Integrates Cisco edge telematics with Splunk’s AI-driven SIEM to easily and instantly detect anomalies such as V2X spoofing and initiate automated containment.

Impact

Eliminate critical operational blind spots, harden industrial edge networks against sophisticated cyber-attacks, and maintain continuous service availability without expanding administrative overhead.

​

  • 100%(3) assets visibility
     

  • 99%(3) reduction in attack propagation
     

  • 50%(2) reduction in incident MTTR
     

  • 60% to 80% reduction in truck rolls to address incidents
