Control: 8.6 Enable Role Based Access Control for Azure Key Vault

Description

WARNING: Role assignments disappear when a Key Vault has been deleted (soft- delete) and recovered. Afterwards it will be required to recreate all role assignments. This is a limitation of the soft-delete feature across all Azure services.

The new RBAC permissions model for Key Vaults enables a much finer grained access control for key vault secrets, keys, certificates, etc., than the vault access policy. This in turn will permit the use of privileged identity management over these roles, thus securing the key vaults with JIT Access management.

Remediation

From Azure Portal

Key Vaults can be configured to use Azure role-based access control on creation. For existing Key Vaults:

  1. From Azure Home open the Portal Menu in the top left corner.
  2. Select Key Vaults.
  3. Open every Key Vault you wish to audit.
  4. Select Access configuration.
  5. Set the Permission model radio button to Azure role-based access control, taking note of the warning message.
  6. Click Save.
  7. Select Access Control (IAM).
  8. Select the Role Assignments tab.
  9. Reapply permissions as needed to groups or users.

Default Value

The default value for Access control in Key Vaults is Vault Policy.

powerpipe control run azure_compliance.control.cis_v200_8_6

Snapshot and share results via Turbot Pipes:
