Identity and Device Verification
Implement MFA everywhere, device health checks, certificate-based identity, and conditional access.
Identity and Device Verification is a free Cyber Security Academy lesson on CoddyKit — lesson 2 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Cyber Security Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Identity Providers (IdP)
An Identity Provider is the central system that authenticates users and issues tokens for other services. Modern IdPs support SSO, MFA, and conditional access. Examples: Okta, Azure AD (Entra ID), Google Workspace, Ping Identity.
Single Sign-On (SSO)
SSO lets users authenticate once with the IdP and access multiple applications without re-entering credentials. Built on SAML 2.0 or OIDC protocols. Security benefit: fewer credentials = fewer credential theft opportunities; security controls centralized at IdP.
SAML vs OIDC
Two dominant SSO protocols:
- SAML 2.0 — XML-based, enterprise, widely supported by legacy apps
- OIDC (OpenID Connect) — JSON/JWT-based, modern, built on OAuth 2.0, used by cloud and mobile apps
Both delegate authentication to the IdP and return a signed token to the app.
Conditional Access Policies
Modern IdPs support conditional access: access decisions based on risk signals:
- User role and group membership
- Device compliance status
- Geographic location
- Time of day
- Risk score (sign-in anomaly)
High-risk signals trigger step-up MFA or block access entirely.
Mobile Device Management (MDM)
MDM enrolls and manages devices, enforcing security policies:
- Require screen lock PIN/biometric
- Require disk encryption
- Force OS updates
- Remote wipe capability
- Compliance reporting to IdP for conditional access
Examples: Microsoft Intune, Jamf (Apple), VMware Workspace ONE.
Device Certificates
Device certificates bind a cryptographic identity to each managed device. Issued by an enterprise CA via MDM. Zero Trust policies can require a valid device certificate before granting access — unmanaged personal devices are blocked even with valid user credentials.
Endpoint Detection and Response (EDR)
Zero Trust uses EDR telemetry as a device health signal. An IdP can query whether EDR is installed and healthy before granting access. A compromised device detected by EDR triggers automatic access revocation through conditional access integration.
Just-in-Time (JIT) Access
JIT access (PIM — Privileged Identity Management) grants elevated permissions only when needed, for a limited duration, requiring approval. No permanently assigned admin roles. Azure AD PIM, AWS IAM temporary credentials, and HashiCorp Vault implement this.
Service-to-Service Identity
Applications also need identity verification. Approaches:
- Service accounts with short-lived tokens
- mTLS — mutual TLS where both client and server present certificates
- SPIFFE/SPIRE — workload identity framework for microservices
Multi-Tenancy and Identity Isolation
In SaaS and cloud environments, identity isolation prevents cross-tenant access. Each customer's identity space must be strictly isolated. A bug that allows one tenant to access another's data is a critical vulnerability.
Identity Governance
Beyond day-to-day authentication, identity governance ensures:
- Regular access reviews (certifications) — managers review who has access
- Automated provisioning/deprovisioning via SCIM
- Orphaned accounts detected and removed
- Separation of duties enforced
Quick Check: Identity Verification
Which Zero Trust component grants elevated permissions only when needed, for a limited time, with approval — rather than permanently assigning admin roles?
Lesson Recap
Zero Trust identity: centralized IdP with SSO (SAML/OIDC), MFA, and conditional access policies. Device verification via MDM compliance checks and device certificates. JIT/PIM eliminates standing admin privileges. Service identity via mTLS and SPIFFE. Identity governance with access reviews and automated SCIM provisioning ensures least privilege is maintained over time.
