IoT security threats highlight the need for zero trust principles

IoT devices have seen a 400% increase in malware attacks compared to the previous year, according to Zscaler. Such attacks pose significant threats to critical OT infrastructure due to malware’s mobility across networks. Cybersecurity experts suggest that adopting a zero trust architecture could minimize IoT security risks. The study also highlighted that the manufacturing sector experiences an average of 6,000 IoT malware attacks every week, disrupting critical OT processes.
