SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Traditional perimeter security authenticates users once at login and trusts them for the entire session, leaving organizations exposed to credential theft, phishing, and token hijacking. This Skill guides the implementation of zero trust identity verification aligned with NIST SP 800-207 and the CISA Zero Trust Maturity Model.

Core Features & Use Cases

  • Phishing-Resistant MFA Deployment: Enroll users in FIDO2/WebAuthn with hardware security keys, disable phishable methods like SMS and voice, and block legacy authentication protocols such as IMAP and POP3.
  • Risk-Based Conditional Access: Configure policies that evaluate device posture, sign-in risk, and location to enforce step-up authentication or block high-risk access attempts.
  • Continuous Access Evaluation: Enable real-time token revocation so disabled or compromised users lose access within minutes, not hours.
  • Use Case: A security engineer rolling out zero trust at their organization uses this Skill to consolidate identity providers, deploy hardware-key MFA, configure conditional access policies, and validate that revocation actually works by testing mid-session user disablement.

Quick Start

Help me implement phishing-resistant MFA and continuous identity verification for zero trust in my Azure AD environment.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement phishing-resistant MFA for zero trust?▼

Enroll all users in FIDO2/WebAuthn using hardware security keys or platform authenticators like Windows Hello and Touch ID. Then disable phishable methods such as SMS and voice calls, and create conditional access policies requiring phishing-resistant authentication for all sign-ins.

What is Continuous Access Evaluation in zero trust?▼

Continuous Access Evaluation (CAE) revokes session tokens in near real time when critical events occur, such as a user being disabled or a password change. It ensures revocation lands within minutes rather than waiting for the full session token lifetime to expire.

Which identity providers support zero trust conditional access?▼

The Skill covers Azure AD (Microsoft Entra), Okta, and Ping Identity as primary identity providers. Risk engines like Microsoft Entra ID Protection and Okta ThreatInsight provide the identity threat detection signals used by conditional access policies.

Why does legacy authentication bypass zero trust MFA policies?▼

Legacy protocols like IMAP, POP3, and SMTP basic auth cannot enforce modern conditional access or MFA, so attackers use them to bypass FIDO2 protections entirely. Blocking legacy authentication is a required step in any zero trust identity deployment.

How do I verify my zero trust identity policies actually work?▼

Disable a test user mid-session and confirm their active token is revoked via CAE, attempt a legacy-auth login and confirm it is blocked, and trigger a high-risk sign-in to verify step-up or block fires in the sign-in logs. Do not trust a policy until you have seen it deny access.
