“Targeting engineers with phishing messages is pretty straight-forward and, if successful, could be extremely damaging. In tandem, while air-gapping offered a degree of protection, the way our nuclear plants, and any infrastructure for that matter, is maintained today means this practice is defunct. We often see engineers ‘plugging’ in their own devices to perform diagnostic checks. Should that person’s device have been compromised, this action could unleash malware directly into the heart of each component being checked, which then crawls and burrows deeper into the infrastructure. Plant managers need to be able to identify and close down anomalous behavior before damage is done. Advanced monitoring and anomaly detection solutions provide actionable intelligence that enable them to identify intrusions and take immediate steps to ensure uptime and resilience of their critical operational technology (OT) environments.”
