Control: 1.2.6 Ensure Multi-factor Authentication is Required for Azure Management

Select on the left side Conditional Access.
Click the + New policy

Default Value

MFA is not enabled by default for administrative actions.

  select
    distinct tenant_id,
    subscription_id,
    _ctx
  from
    azure_tenant
)
select
  p.id as resource,
  case
    when p.built_in_controls @> '["mfa"]' then 'ok'
    else 'alarm'
  end as status,
  case
    when p.built_in_controls @> '["mfa"]' then p.display_name || ' MFA enabled.'
    else p.display_name || ' MFA disabled.'
  end as reason,
  t.tenant_id
  
from
  distinct_tenant as t,
  azuread_conditional_access_policy as p;
