(TLP:CLEAR) CISA Releases Part One of Zero Trust Microsegmentation Guidance

TLP:CLEAR

Author: Chase Snow

Created: Thursday, July 31, 2025 - 15:05

Categories: Cybersecurity, Federal & State Resources, Security Preparedness

Summary: On Tuesday, CISA released a new guide titled “Microsegmentation in Zero Trust, Part One: Introduction and Planning.” The guide is part of an ongoing effort to support Federal Civilian Executive Branch (FCEB) agencies implementing zero trust architectures (ZTAs). CISA plans to release a subsequent technical guide to offer detailed implementation scenarios and technical considerations for implementation teams.

Analyst Note: 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. WaterISAC encourages members to review the guide to better implement zero trust principles in their defense strategies.
