Zero Trust Guidance for IoT
Released: 05/27/2025
Traditional security models treat Internet of Things (IoT) security solely as a long-term supply chain concern. This is a significant oversight in today's rapidly evolving threat landscape. IoT security cannot be an afterthought when vulnerabilities introduced by IoT devices and their unique protocols are immediate and can have serious repercussions.
A more effective approach to enterprise security is Zero Trust. This model assumes that you cannot trust any user or device by default. Understanding the practical application of Zero Trust in the context of IoT helps organizations establish necessary security measures. As such, this publication provides a 5-step methodology for architecting and implementing Zero Trust, specifically tailored for IoT technology:
- Define the protect surface
- Map the transaction flows
- Build an architecture
- Create a policy
- Monitor and maintain the network
This detailed guidance enables organizations to effectively categorize and secure the IoT devices in their environments. Ultimately, organizations will be able to ensure protection against evolving IoT threats while maintaining critical operational resilience.
Key Takeaways:
- The unique challenges in IoT security
- How Zero Trust scales naturally with the complexity of IoT through modular controls
- How to deploy Zero Trust in IoT environments
- Attack vectors that can help measure the effectiveness of a Zero Trust implementation
- How Original Equipment Manufacturers (OEMs) can demonstrate compliance with security standards
