Abstract

The increasing adoption of IoT devices in corporate environments has expanded the attack surface for potential cyber threats, highlighting the limitations of traditional security approaches. The paper focuses on optimized Zero Trust Architecture tailored for IoT devices, it does so use the recommendations by Microsoft Threat modeling tool and simulating the network using Cisco Packet Tracer, thus leveraging both STRIDE model and ZTA principles. It was seen that common attacks on IoT devices such as VLAN hopping, ARP poisoning, and MAC flooding that often are being perpetrated because of vulnerabilities in end point devices or open ports are mitigated if Zero Trust principles are followed. The results demonstrate the efficiency of key principles of ZTA such as trust verification, network segmentation and the least privilege principle in mitigating lateral movement and unauthorized access.
