NSA Publishes New Zero Trust Implementation Guidelines

NSA released new Zero Trust Implementation Guidelines outlining Phase One and Two to guide organizations from discovery to target-level maturity, defining activities and capabilities to establish a secure baseline and integrate core zero trust solutions. The guidance shifts focus from perimeter defenses to continuous authentication and authorization with post-login evaluation, aligns with NIST SP 800-207, CISA Zero Trust Maturity Model 2.0, and the DoW reference architecture, and underscores that zero trust is an ongoing operating model rather than a one-time deployment.
