Implementing Identity Verification for Zero Trust

Prerequisites

• Understanding of zero trust principles (NIST SP 800-207)
• Familiarity with identity providers (Azure AD, Okta, Ping Identity)
• Knowledge of authentication protocols (SAML 2.0, OIDC, FIDO2)
• Understanding of MFA and passwordless authentication

Overview

Identity is the foundational pillar of zero trust architecture. NIST SP 800-207 mandates that all resource authentication and authorization are dynamic and strictly enforced before access is allowed. Identity verification in zero trust goes beyond traditional username/password by implementing continuous, risk-adaptive authentication using multiple signals including device posture, behavioral biometrics, location, and network context.

This skill covers implementing phishing-resistant MFA, continuous identity verification, risk-based conditional access, and identity governance aligned with the CISA Zero Trust Maturity Model Identity Pillar.
