The new set of identity related recommendations when GA on 2023-05-01: https://github.com/MicrosoftDocs/azure-docs/commit/aba0c46fdabe84065951c96a7df75333a0493cac#diff-dbd404e58cedaa40736d88385d006caf82189af9cac95af849538aab5c5b57d8L70-L78

As a result multiple items are missing from Enable MFA category on Secure score recommendations:

  • Only one recommendation/policy assignment visible. Should have three
  • Only one subscription being listed. Should have three

MFA related recommendations:

Resource graph query to find the underlying issue:

PolicyResources
| where type =~ 'Microsoft.PolicyInsights/PolicyStates'
| extend complianceState = tostring(properties.complianceState)
| extend
	resourceId = tostring(properties.resourceId),
	policyAssignmentId = tostring(properties.policyAssignmentId),
	policyAssignmentScope = tostring(properties.policyAssignmentScope),
	policyAssignmentName = tostring(properties.policyAssignmentName),
	policyDefinitionId = tostring(properties.policyDefinitionId),
	policyDefinitionReferenceId = tostring(properties.policyDefinitionReferenceId),
	stateWeight = iff(complianceState == 'NonCompliant', int(300), iff(complianceState == 'Compliant', int(200), iff(complianceState == 'Conflict', int(100), iff(complianceState == 'Exempt', int(50), int(0))))),
    complianceReasonCode = tostring(properties.complianceReasonCode)
| where policyDefinitionId contains "e3e008c3-56b9-4133-8fd7-d3347377402a"
    or policyDefinitionId contains "931e118d-50a1-4457-a5e4-78550e086c52"
    or policyDefinitionId contains "81b3ccb4-e6e8-4e4a-8d05-5df25cd29fd4"
    or policyDefinitionId contains "339353f6-2387-4a45-abe4-7f529d121046"
    or policyDefinitionId contains "94e1c2ac-cbbe-4cac-a2b5-389c812dee87"
    or policyDefinitionId contains "e9ac8f8e-ce22-4355-8f04-99b911d6be52"
    or policyDefinitionId contains "0cfea604-3201-4e14-88fc-fae4c427a6c5"
    or policyDefinitionId contains "8d7e1fde-fe26-4b5f-8108-f8e432cbc2be"
| order by subscriptionId asc, policyDefinitionReferenceId asc, complianceState asc
| project subscriptionId, policyDefinitionReferenceId, complianceState, complianceReasonCode

Results:

enter image description here

From results we can see that policies are on NonCompliant state because underlying Microsoft.Security/assessments resources are missing from the subscription.

Regulatory compliance also displays wrong number of resources:

  • Anyone got insights if this is a known issue?
  • Any workarounds? Should I trigger something to re-calculate those assesment findings?
  • ATM we cannot trust Defender's green findings at all.
