The firewall is no longer enough. Attackers move inside networks, exploiting trust gaps and weak validation. Zero Trust changes the rules—verify everything, assume nothing—and the Zero Trust Maturity Model gives teams a framework to measure progress. QA testing must align with that framework or security promises will fail in production.
The Zero Trust Maturity Model defines stages: Traditional, Advanced, and Optimal. At each stage, identity, device health, and access control are strengthened, with continuous validation becoming the standard at higher levels. QA testing is the proving ground for these controls. Without precise, automated test coverage, new features can roll out with unseen policy drift or broken enforcement.
Zero Trust QA focuses on three pillars. First, identity authentication testing: validating multifactor, single sign-on, and session lifetimes under real-world load. Second, authorization checks: confirming role-based policies and contextual rules work as defined, including edge cases where access should be denied. Third, continuous monitoring: testing endpoint telemetry, anomaly detection, and automated responses in integrated environments.
