NSA Launches Primer and Discovery Phase to Start Zero Trust Implementation Series

Overview

• The Primer defines a zero‑trust mindset that assumes compromise and stresses rigorous authentication, explicit authorization, least‑privilege access, deny‑by‑default, and continuous monitoring.
• The Discovery Phase directs organizations to inventory data, applications, assets, services, and access activity to establish a reliable baseline for planning and prioritization.
• The Zero Trust Implementation Guidelines are structured for phased, modular adoption so teams can implement capabilities incrementally based on current maturity.
• The NSA describes these releases as gateway documents for system owners, cybersecurity professionals, and other stakeholders in advance of Phase 1 and Phase 2 guidance.
• The agency frames the recommendations as practical and actionable, with reporters noting their relevance to both public‑sector and private‑sector environments.
