Adapting Zero Trust Principles to Operational Technology
Summary
CISA, along with several other government agencies, has released joint guidance on adapting Zero Trust principles to Operational Technology (OT) environments. This guidance addresses the increasing risks associated with the convergence of IT and OT systems, which were traditionally isolated but are now becoming more interconnected. It aims to help OT owners and operators implement Zero Trust architectures by focusing on asset visibility, supply chain risk, identity and access management, and layered security measures.
IFF Assessment
The guidance promotes the adoption of Zero Trust principles, which are considered a strong defense strategy, making it good news for defenders.
Defender Context
This guidance is crucial for defenders managing Operational Technology systems, as it provides a framework for securing increasingly interconnected environments. Organizations should focus on asset inventory, robust access controls, and understanding the unique operational constraints of OT to effectively implement Zero Trust principles and mitigate risks.
