Description

Enabling logging for Azure Key Vault ensures that all access and management activities are captured and can be monitored for unauthorized or anomalous activity. Without logging enabled—such as omitting a azurerm_monitor_diagnostic_setting resource—critical security events and access records would not be recorded, making it difficult to detect potential breaches or comply with audit requirements. A secure configuration includes adding a diagnostic setting. For example:

resource "azurerm_monitor_diagnostic_setting" "example" {
  name               = "example"
  target_resource_id = azurerm_key_vault.example.id
  storage_account_id = azurerm_storage_account.example.id

  log {
    category = "AuditEvent"
    enabled  = true
  }
}

This logs Key Vault events and helps ensure accountability and traceability for sensitive key and secret operations.
