Vulnerabilities in Operational Technology

Richard Clarke discusses the vulnerabilities in operational technology (OT) and supervisory control and data acquisition (SCADA) systems. The OT and IT worlds don't interact well, creating a huge vulnerability. People are connecting the two systems, which can lead to security issues. Clarke shares a war story about a pipeline company that had a command center designed to survive a nuclear war, but employees used weak passwords and wrote them on Post-it notes.
