This infographic uses intelligence-driven threat scenarios to show oil and gas organizations how to prioritize defenses and cybersecurity investments. The featured TRISIS case traces an attack from credential capture and VPN access through OT lateral movement to malicious logic delivered to a Triconex Safety Instrumented System using the legitimate TriStation protocol. The incident demonstrated how attackers could attempt to disable safety-critical functions and leave a plant exposed to unsafe conditions. Defenses are organized around the SANS 5 Critical Controls: ICS-specific incident response, defensible architecture, continuous OT network monitoring, secure remote access, and risk-based vulnerability management. Additional VOLTZITE, AZURITE, and hacktivist scenarios highlight cellular g
