Control: 5.2.2.7 Enable Identity Protection sign-in risk policies

Description

Microsoft Entra ID Protection sign-in risk detects risks in real-time and offline. A risky sign-in is an indicator for a sign-in attempt that might not have been performed by the legitimate owner of a user account.

Note: While Identity Protection also provides two risk policies with limited conditions, Microsoft highly recommends setting up risk-based policies in Conditional Access as opposed to the "legacy method" for the following benefits:

Enhanced diagnostic data
Report-only mode integration
Graph API support
Use more Conditional Access attributes like sign-in frequency in the policy

Remediation

To configure a Sign-In risk policy, use the following steps:

Navigate to Microsoft Entra admin center https://entra.microsoft.com/.
Click to expand Protection > Conditional Access select Policies.
Create a new policy by selecting New policy.
Set the following conditions within the policy.
- Under Users choose All users.
- Under Target resources choose All resources (formerly 'All cloud apps').
- Under Conditions choose Sign-in risk then Yes and check the risk level boxes High and Medium.
- Under Grant click Grant access then select Require multifactor authentication.
- Under Session select Sign-in Frequency and set to Every time.
- Click Select.
Under Enable policy set it to Report-only until the organization is ready to enable it.
Click Create.

Note: Break-glass accounts should be excluded from all Conditional Access policies.

SQL

This control uses a named query:

  select
    tenant_id,
    count(*)
  from
    azuread_conditional_access_policy
  where
    users->'includeUsers' ?& array['All'] and
    jsonb_array_length(users -> 'excludeUsers') = 0 and
    jsonb_array_length(sign_in_risk_levels) != 0 and
    applications->'includeApplications' ?& array['All'] and
    jsonb_array_length(applications -> 'excludeApplications') = 0 and
    built_in_controls ?& array['mfa']
  group by
    tenant_id
),
tenant_list as (
  select
    distinct on (tenant_id) tenant_id,
    _ctx
  from
    azuread_user

select
  t.tenant_id as resource,
  case
    when (select count from block_legacy_authentication where tenant_id = t.tenant_id) > 0 then 'ok'
    else 'alarm'
  end as status,
  case
    when (select count from block_legacy_authentication where tenant_id = t.tenant_id) > 0 then t.tenant_id || ' has sign-in risk policies enabled.'
    else t.tenant_id || ' has sign-in risk policies disabled.'
  end as reason
