Is offline testing in power systems safe anymore from cyber intrusion? In this episode of Energy Talks, Christopher Pritchard, who is head of product management at OMICRON, maintains that the idea that offline equals security just does not hold up anymore. He explains how malware can infiltrate even disconnected systems and be passed on to the substation as soon as these systems are connected to the network. Christopher then describes how new cybersecurity features are being added to the latest testing devices to make offline testing less of a security risk.
