What this domain covers

What to know about Implement Azure security

Be able to choose the right identity (managed identity vs service principal), grant least-privilege Key Vault permissions via RBAC or access policies, and wire secrets into App Service or Functions using Key Vault references—without storing credentials in configuration.

Assigning Key Vault RBAC roles versus access policies for least-privilege team access

Using managed identities with DefaultAzureCredential to read Key Vault secrets without stored credentials

Referencing Key Vault secrets from App Service and Azure Functions via Key Vault references

Scoping Key Vault access with Microsoft Entra ID app registrations, service principals, and access policies

Watch out for

Common Implement Azure security exam traps

  • ▸Mixing Key Vault access policies with Azure RBAC on the same vault, which causes conflicting or unexpected permission evaluation.
  • ▸Granting broad roles like Key Vault Administrator when read-only or list-only access was explicitly required by the scenario.
  • ▸Storing secrets in application settings or source instead of using managed identities and Key Vault references, violating no-credential policies.

A financial services company uses Azure Container Instances (ACI) to run batch processing jobs. Each job processes sensitive financial data and must use a custom container image stored in Azure Container Registry (ACR). The security requirements are: the ACI container must authenticate to ACR using a managed identity, the container must run as a non-root user, and all secrets must be injected via environment variables from Azure Key Vault using the managed identity. The ACI instance must also be deployed into a virtual network (VNet) to restrict network access. What configuration should you use?
