This project calls for the implementation of a comprehensive Transit Cyber Security and Risk Mitigation Project within the Chicago Transit Authority (CTA). Project will include the upgrade, modernization, and hardening of CTA’s core firewall and network infrastructure, adding cyber security tools and services to identify, protect, detect, respond, and recover from and against cyber threats and vulnerabilities. The project will address findings, recommendations, and best practices from recent Threat and Vulnerability Assessments (TVA) and specifically target CTA systems potentially vulnerable from the global Solarwinds hack of 2020.
