Overview
Project Title	The Application of Zero Trust Principals to Space Systems
Approval	Draft
Document Number
Charter	1.02 Security Working Group
Document Type	Green
Description of Document	This document will provide information on the application of Zero Trust Principals to space systems: ground systems, cloud-base systems, and flight systems. Zero Trust advocates breaking a network into micro-segments, and performing continual access control checking rather than assuming a single access boundary.
Applicable Patents	There are no patent issues for this technology that are known by the CCSDS community
Patent Comments
Survey of Similar Standards Documents or Projects Undertaken in Other Bodies and elsewhere in CCSDS	NIST SP 800-207, CISA Zero Trust Maturity Model, Department of Defense (DoD) Zero Trust Reference Architecture
