Texas’ critical infrastructure—power grids, water systems, transportation, and emergency services—is increasingly vulnerable to cyberattacks that can disrupt daily life and public safety. In this session, we’ll explore how legacy systems, insecure remote access, and IT/OT convergence have expanded the attack surface for threat actors ranging from ransomware gangs to nation-state adversaries. Through real-world case studies and technical insights, we’ll break down how to inventory and monitor OT assets, implement effective network segmentation, and build a Zero Trust foundation for critical systems. We’ll also cover emerging technologies like passive ICS detection, AI-driven anomaly monitoring, and incident response tactics for industrial environments. Attendees will walk away with actionable strategies to reduce risk, strengthen inter-agency coordination, and secure the infrastructure that keeps Texas running. Identify and map vulnerabilities across converged IT/OT systems in critical infrastructure environments. Apply technical best practices for network segmentation, asset visibility, and Zero Trust principles in industrial settings. Implement incident response planning and cross-sector coordination strategies tailored for critical infrastructure protection.
