Control: 5.2.2.6 Enable Azure AD Identity Protection user risk policies

Description

Azure Active Directory Identity Protection user risk policies detect the probability that a user account has been compromised.

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

With the user risk policy turned on, Azure AD detects the probability that a user account has been compromised. Administrators can configure a user risk conditional access policy to automatically respond to a specific user risk level.

Remediation

To configure a User risk policy, use the following steps:

Navigate to the Microsoft Entra admin center https://entra.microsoft.com.
Click expand Protection > Conditional Access select Policies.
Create a new policy by selecting New policy.
Set the following conditions within the policy:
- Under Users or workload identities choose All users.
- Under Cloud apps or actions choose All cloud apps.
- Under Conditions choose User risk then Yes and select the user risk level High.
- Under Access Controls select Grant then in the right pane click Grant access then select Require multifactor authentication and Require password change.
- Under Session ensure Sign-in frequency is set to Every time.
Click Select.
You may opt to begin in a state of Report Only as you step through implementation however, the policy will need to be set to On to be in effect.
Click Create.

Note: for more information regarding risk levels refer to Microsoft's Identity Protection & Risk Doc

Usage

Run the control in your terminal:

powerpipe control run microsoft365_compliance.control.cis_v300_5_2_2_6

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run microsoft365_compliance.control.cis_v300_5_2_2_6 --share

SQL

This control uses a named query:

with block_legacy_authentication as (
  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(user_risk_levels) != 0
    and applications->'includeApplications' ?& array['All']
    and jsonb_array_length(applications -> 'excludeApplications') = 0
    and built_in_controls ?& array['passwordChange']
  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 user risk policies enabled.'
    else t.tenant_id || ' has user risk policies disabled.'
  end as reason
  , t.tenant_id as tenant_id
from
  tenant_list as t;
