SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Design authentication strategy per user population, selecting mechanisms and governing lifecycle.

Core Features & Use Cases

  • Per-population design of authentication mechanisms and MFA posture
  • Lifecycle coverage: registration, auth, recovery, rotation, revocation
  • Threat mitigation mapping to mechanisms and recommended tooling
  • Diagrammatic guidance and IdP/tooling references
  • Clear guidance for per-population decision matrices and roll-out

Quick Start

Define per-population authentication mechanisms, MFA posture, and lifecycle for your product and user populations.

FAQPage Schema
How do I design an authentication strategy for different user populations?

Designing an authentication strategy per user population involves selecting mechanisms, defining MFA posture, and managing the lifecycle for customers, employees, partners, and services. This ensures mechanisms map to identified risks and population needs.

What is per-population authentication lifecycle management?

Per-population authentication lifecycle management covers registration, initial and subsequent authentication, step-up authentication, recovery, rotation, and revocation. It enforces mechanism choices and threat mitigations tailored to each user group.

How do I map threat modeling to authentication mechanisms?

Map threat modeling to authentication mechanisms by identifying risks per user population and selecting controls like MFA, session management, and revocation to mitigate them. This process yields clear decision matrices and tooling references.

How do I configure step-up authentication and recovery for different user types?

Configure step-up authentication and recovery by defining per-population mechanism choices and MFA posture. This governs lifecycle stages like account recovery and rotation, ensuring threat mitigations map to identified risks.

What is the best way to manage SSO and MFA posture across partners and employees?

The best way to manage SSO and MFA posture across partners and employees is per-population strategy design. It enforces distinct mechanism choices, session management, and revocation policies, mapping threat mitigations to each group's specific risks.

When do I need per-population authentication design instead of a single strategy?

You need per-population authentication design when customers, employees, partners, and services require distinct mechanisms, MFA postures, and lifecycle management. A single strategy fails to map threat mitigations to the varied risks of different user groups.
