CISA Releases Part One of Zero Trust Microsegmentation Guidance

CISA released Microsegmentation in Zero Trust, Part One: Introduction and Planning as part of its ongoing efforts to support Federal Civilian Executive Branch (FCEB) agencies implementing zero trust architectures (ZTAs). 

This guidance provides a high-level overview of microsegmentation, focusing on its key concepts, associated challenges and potential benefits, and includes recommended actions to modernize network security and advance zero trust principles.

Microsegmentation is a critical component of ZTA that reduces the attack surface, limits lateral movement, and enhances visibility for monitoring smaller, isolated groups of resources.

While the guidance focuses on FCEB references, its principles are applicable to any organization. As part of its Journey to Zero Trust series, CISA plans to release a subsequent technical guide to offer detailed implementation scenarios and technical considerations for implementation teams. Visit our Zero Trust webpage for more information and resources.
