Exempt a specific container in MDC

gokhantatar — Thu, 25 Jun 2026 20:22:45 GMT

You don't need a full exemption for this — the built-in policy behind "Immutable (read-only) root filesystem should be enforced for containers" already supports per-container and per-image exclusions natively, which is more precise than exempting at the resource/cluster level.

This recommendation is implemented via the Azure Policy Add-on for Kubernetes (Gatekeeper constraint) as part of Defender for Cloud's data plane hardening. The underlying policy definition supports these parameters:

excludedContainers — exclude by container name
excludedImages — exclude by image (supports prefix matching, e.g. myregistry.azurecr.io/legacy-app:*)
excludedNamespaces — exclude entire namespaces (e.g., kube-system, useful for system pods that legitimately can't run read-only)

To configure: Defender for Cloud → Recommendations → select this recommendation → Take action tab, where you can set these parameters directly without touching raw policy JSON. Alternatively, if you manage policy via Environment Settings → Security policies → Standards, you can set the same parameters on the standard assignment.

Given you said multiple containers across airflow/db1, airflow/sql1, etc. show "Unhealthy" — if these are legitimate exceptions (e.g., a database container that needs to write to its filesystem by design, not just a misconfiguration), excludedContainers naming each container is the cleanest fix and keeps the recommendation enforcing everywhere else in the cluster. I'd reserve a full policy exemption (Azure Policy exemption resource) for cases where you need it tracked for compliance/audit purposes specifically — the parameter-based exclusion is the more "native" and maintainable fix for ongoing operational cases like this.

Exempt - Azure CSPM Recommendation" (Terraform exemption

gokhantatar — Thu, 25 Jun 2026 20:22:04 GMT

The reason you're not finding a standalone policyAssignmentId/policyDefinitionId for this specific recommendation is that it isn't a standalone assignment — it's one control inside the built-in CSPM initiative (the "ASC Default" / Microsoft Cloud Security Benchmark assignment). That initiative does have an assignment ID; you just need to target the specific control within it, not look for a separate one.

In azurerm_resource_policy_exemption (or the subscription/resource-group variants), the relevant fields are:

policy_assignment_id → the ID of the initiative assignment (ASC Default / MCSB), not a per-recommendation assignment
policy_definition_reference_ids → an array scoping the exemption to just this one control instead of the whole initiative

resource "azurerm_resource_policy_exemption" "function_app_network_exemption" {

name = "exempt-function-network-restriction"

resource_id = azurerm_linux_function_app.example.id

policy_assignment_id = data.azurerm_subscription_policy_assignment.asc_default.id

policy_definition_reference_ids = [

"<reference-id-for-the-specific-control>"

]

exemption_category = "Waiver" # or "Mitigated" if an equivalent control exists

expires_on = "2026-12-31T00:00:00Z"

}

To find the policy_definition_reference_id for this specific control: in the Azure Portal, go to Policy → Definitions, search for "Restricted network access should be configured on Internet exposed Function app" to get its definition ID, then open the initiative definition (ASC Default) and find the matching entry in its policyDefinitions[].policyDefinitionReferenceId array — that string is what goes in the array above.

Two things worth deciding upfront before automating this:

Waiver vs Mitigated — if you've genuinely restricted access another way (e.g., Private Endpoint), use Mitigated so it's distinguishable from accepted risk in reporting.
Consider whether the exemption belongs at the resource scope (just this Function App) vs resource group/subscription — narrower is safer, but if you have a pattern of similar apps, a tagged-based resourceSelectors block can scale this without per-resource blocks.

Exempt - Azure CSPM Recommendation

ABhatia610 — Wed, 17 Jun 2026 00:40:30 GMT

We are implementing creating exemptions on policies through Terraform.

Is there a way to exempt this specific Azure CSPM standard policy "Restricted network access should be configured on Internet exposed Function app" through Terraform since it does not have any policyassignmentid and policyid.

I think this standard policy cannot be exempted with this code. Please confirm.

My understanding is this is Assessment type and has no policy id or policy assessment id. I can exempt through Azure Portal but not from Terraform.

Any guidance is greatly appreciated.

resource "azurerm_subscription_policy_exemption" "this" {

for_each = local.subscription_exemptions

name = each.key

subscription_id = each.value.resource_id

policy_assignment_id = each.value.policy_assignment_id

policy_definition_reference_ids = each.value.policy_definition_reference_ids

exemption_category = each.value.category

expires_on = each.value.expires_on

description = "Ticket: ${each.value.ticket} | ${each.value.remediation_plan}"

metadata = jsonencode(merge(var.tags, {

owner = each.value.owner

ticket = each.value.ticket

risk_level = each.value.risk_level

remediation_plan = each.value.remediation_plan

approved_by = each.value.approved_by

approval_date = each.value.approval_date

environment = var.environment

managed_by = "terraform"

}))

}

Thanks,

Exempt a specific container in MDC

ABhatia610 — Tue, 09 Jun 2026 15:25:11 GMT

I have this recommendation showing in defender.

Immutable (read-only) root filesystem should be enforced for containers

There are multiple containers inside AKS that are showing as "Unhealthy"

airflow/db1
airflow/sql1
airflow/scheduler1

Is there a way to exempt a specific container or the whole recommendation has to be exempted.

Thanks

Microsoft.Security/policies GET endpoint returning 404 — deprecated? What is the replacement?

mahendra_kamble_sumo — Fri, 15 May 2026 07:58:31 GMT

Hi,

We are using the Azure Security Center REST API (api-version=2015-06-01-preview) to retrieve security policies for a subscription. We are hitting a 404 Not Found error on the Get endpoint while the List

endpoint works fine. Looking for clarification on whether this resource type has been deprecated and what the modern replacement is.

---

Endpoints in use

List Security Policies (WORKING):

GET https://management.azure.com/subscriptions/{subscriptionId}/providers/microsoft.Security/policies?api-version=2015-06-01-preview

This returns a valid JSON response with an array of policies, each having an id, name, type, and a properties object containing policyLevel, recommendations, pricingConfiguration,

securityContactConfiguration, etc.

Get Security Policy by Name (BROKEN):

GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Security/policies/{policyName}?api-version=2015-06-01-preview

---

Error received

Not Found for url:

https://management.azure.com/subscriptions/<sub-id>/resourceGroups/AzureEventHubIT-resource-group/providers/Microsoft.Security/policies/AzureEventHubIT-resource-group?api-version=2015-06-01-preview

HTTP Status: 404 Not Found

---

What we've observed

- The List endpoint works and returns policies whose id values follow this exact structure:

/subscriptions/{sub-id}/resourceGroups/{rg-name}/providers/microsoft.Security/policies/{policy-name}

- The policy name in the List response matches the resource group name (1:1 mapping), so we are passing the correct value to the Get endpoint.

- Despite using the exact name and resource group from the List response, the Get endpoint returns 404.

- We also checked the https://learn.microsoft.com/en-us/rest/api/defenderforcloud/operation-groups?view=rest-defenderforcloud-2015-06-01-preview and noticed that Security Policies does not appear as a

documented operation group in any version — including 2015-06-01-preview. The only documented groups for that version are: Discovered Security Solutions, Locations, Operations, and Tasks.

---

Questions

1. Has the Microsoft.Security/policies resource type at the resource group scope been officially deprecated or removed? If so, is there a migration guide or announcement?

2. Why does the List endpoint still respond successfully while the individual Get endpoint returns 404? Is the List endpoint returning legacy/cached data?

3. What are the recommended replacement APIs for the functionality that was in the old policies resource? Specifically we need equivalents for:

- properties.pricingConfiguration → Is this now covered by https://learn.microsoft.com/en-us/rest/api/defenderforcloud/pricings/get?view=rest-defenderforcloud-2024-01-01?

- properties.recommendations (patch, antimalware, diskEncryption, etc.) → Is this now https://learn.microsoft.com/en-us/rest/api/defenderforcloud/assessments?view=rest-defenderforcloud-2020-01-01?

- properties.securityContactConfiguration → Is this now Microsoft.Security/securityContacts (2020-01-01-preview)?

4. Is there any announced retirement date for the List endpoint as well?

Any official documentation links or migration guides would be very helpful.

Thank you.

Microsoft Defender for Cloud

Lucaraheller — Tue, 27 Jan 2026 11:31:58 GMT

For security operations teams managing Microsoft 365 and Azure environments, knowing which event logs to monitor in the Defender portal is fundamental. The right logs give you visibility into identity threats, device compromise, and policy violations before they escalate.

Here are the most critical event log categories:

## 1. Sign-In Logs (Entra ID)

**Location:** Microsoft Entra ID > Sign-in logs

Monitor failed sign-ins, unfamiliar locations, Conditional Access failures, and risky sign-ins flagged by Identity Protection. Identity is the primary attack surface—these logs detect credential compromise and lateral movement.

## 2. Audit Logs (Entra ID)

**Location:** Microsoft Entra ID > Audit logs

Track changes to user accounts, privilege escalations, Conditional Access modifications, and application consent grants. Unauthorized administrative changes can bypass security controls.

## 3. Device Compliance Logs (Intune)

**Location:** Microsoft Intune > Devices > Monitor

Monitor non-compliant devices, enrollment failures, and policy errors. Non-compliant endpoints represent unmanaged risk.

## 4. Threat & Vulnerability Management

**Location:** Microsoft Defender > Endpoints > TVM

Track critical vulnerabilities, missing updates, and exposed credentials. Proactive vulnerability management prevents exploitation.

## 5. Alerts and Incidents (Defender XDR)

**Location:** Microsoft Defender > Incidents & Alerts

Your central SOC dashboard—monitor high-severity alerts for ransomware, credential theft, and lateral movement across endpoints, identities, email, and apps.

## 6. Cloud App Activity Logs

**Location:** Defender for Cloud Apps > Activity log

Detect unusual file downloads, admin activity from unmanaged devices, and OAuth app permissions. These logs reveal unauthorized data exfiltration and risky SaaS behavior.

## 7. Email Threat Logs

**Location:** Microsoft Defender > Email & Collaboration > Threat Explorer

Monitor phishing attempts, malware attachments, and spoofed emails. Email remains the most common attack vector.

## 8. Cloud Security Alerts

**Location:** Microsoft Defender for Cloud > Security alerts

Track misconfigurations, policy violations, and threats across Azure subscriptions and hybrid workloads. Essential for cloud infrastructure protection and compliance monitoring.

## How to Use These Logs Effectively

1. Set up automated alerts in Sentinel

2. Establish baselines to detect anomalies

3. Correlate across sources for full attack context

4. Automate response with AIR features

5. Review high-severity logs weekly

Defender for servers (P1)

Diddler431 — Mon, 12 Jan 2026 09:28:29 GMT

Hey guys,

I enabled my Defender for cloud trial licens (P1) for my Windows servers.

They are onboarded and i can see them visually in the (security.microsoft.com) EDR Portal.

My enforcement scope is set to Intune - so all my AV policies etc are created there.

I want to create a AV Policy for my Windows servers but i can't see the objects in Entra.

What is best practice. To register them in Entra manually or should it automaticlly create a object in Entra during the onboarding process?

Can't create & assign a AV policy etc until i create a group and put all my servers into that group.

Any ideas?

Also might be worth mentioning i see that they are managed by "unknown" and not Microsoft Sense? Should i point back the scope to the Defender portal? Whilst my endpoints are managed by Intune.

Updating SDK for Java used by Defender for Server/CSPM in AWS

terruahmad — Mon, 29 Dec 2025 17:26:21 GMT

Hi,

I have a customer who is Defender for Cloud/CSPM in AWS. Last week, Cloud AWS Health Dashboard lit up with a recommendation around the use of AWS SDK for Java 1.x in their organization. This version will reach end of support on December 31, 2025. The recommendation is to migrate to AWS SDK for Java 2.x. The issue is present in all of AWS workload accounts.

They found that a large amount of these alerts is caused by the Defender CSPM service, running remotely, and using AWS SDK for Java 1.x. Customer attaching a couple of sample events that were gathered from the CloudTrail logs. Please note that in both cases:

assumed-role: DefenderForCloud-Ciem
sourceIP: 20.237.136.191 (MS Azure range)
userAgent: aws-sdk-java/1.12.742 Linux/6.6.112.1-2.azl3 OpenJDK_64-Bit_Server_VM/21.0.9+10-LTS java/21.0.9 kotlin/1.6.20 vendor/Microsoft cfg/retry-mode/legacy cfg/auth-source#unknown

Can someone provide guidance about this? How to find out if DfC is going to leverage AWS SDK for Java 2.x after Dec 31, 2025?

Thanks,

Terru

Automate Defender for Cloud settings: FIM, Vulnerability Assessment, and Guest Configuration Agent

Pascal2 — Mon, 17 Nov 2025 13:27:07 GMT

I’m working on automating the configuration of Microsoft Defender for Cloud – Server Plans across multiple subscriptions (100+), including any newly deployed subscriptions. The goal is to avoid manual changes and ensure compliance from day one.

Current Setup:

I’ve used the built-in policy: Configure Microsoft Defender for Servers plan, which successfully enables:
- Defender for Cloud Plan P2
- Endpoint Protection
- Agentless scanning
I attempted to copy this policy and add parameters for Vulnerability Assessment, but the assignment fails with an error.

What I’ve Tried:

For File Integrity Monitor: Policy name → Configure ChangeTracking Extension for Windows virtual machines
For Vulnerability Assessment: Policy name → Configure machines to receive a vulnerability assessment provider
Assigning these policies works on my non-prod subscription, but the toggle in Defender for Cloud → Environment Settings remains No.

Challenge: How can I ensure these options (File Integrity Monitoring, Vulnerability Assessment, and preferably Guest Configuration Agent) are automatically enabled for:

All existing subscriptions
Any new subscriptions created in the future

Goal:

No manual intervention in Defender for Cloud portal
Fully automated via Azure Policy or another recommended approach

uestions:

Is there a way to extend the built-in policy or create a custom initiative that enforces these settings at the subscription level?
Are there ARM templates, Bicep modules, Powershell scripts or REST API calls that can toggle these settings programmatically?
Any best practices for ensuring compliance across multiple subscriptions?

Any help is much appreciated and looking forward to your expertise!
Thank you in advance.

Best Regards,

Pascal Slot

About Defender for Cloud aggregated logs in Advanced Hunting

Molx32 — Wed, 08 Oct 2025 13:31:18 GMT

Hi,

I create this threat hoping that the Microsoft team will read and hopefully provide insights about future changes and roadmap.

When SOC teams use a non-Microsoft SIEM/SOAR, they need to export logs from M365 and Azure, and send them to the third-party SIEM/SOAR solution.

• For M365 logs, there is the M365XDR connector that allows exporting logs using an Event Hub.

• For Azure logs, we used to configure diagnostics settings and send them to an Event Hub.

This began to change with new features within Defender for Cloud (c.f. picture).:

• Defender for Resource Manager now sends Azure Activity logs to M365XDR portal, and can be exported using M365XDR Streaming API

• Defender for Storage now sends logs to M365XDR portal, and can be exported using M365XDR Streaming API (c.f. https://www.youtube.com/watch?v=Yraeks8c8hg&t=1s).

This is great as it is easy to configure and doesn't interfere with infrastructure teams managing operational logs through diagnostic settings.

I have two questions :

• Is there any documentation about this? I didn't find any?

• What can we expect in the future weeks, months regarding this native logs collection feature through various Defender for Cloud products? For example, can we expect Defender for SQL to send logs to M365XDR natively?

Thanks for you support!

Defender for Cloud DCR

edwaro3 — Mon, 28 Jul 2025 14:25:43 GMT

Enabling Defender for Servers Plan 2 and creating a custom DCR to enable the 500MB ingestion into log analytics. The workspace I am sending the logs to is connected to Sentinel. When I looked at creating the DCR I received this pop-up

If I enable the Sentinel connector, will this duplicate the cost of the logs or will the connector just enable the data to be surfaced in Sentinel?

Is setting an index tag in Azure Defender for Cloud during file write an atomic operation?

vitoiacono — Fri, 25 Jul 2025 11:12:35 GMT

Hi,
When using Azure Defender for Cloud, is setting an index tag at the same time as writing a file considered an atomic operation? Or is there a propagation delay before the tag becomes fully available and effective for search and policy enforcement?
Any insights or official documentation references would be appreciated!

File Integrity Monitoring - Agentless Issues in Detecting Changes to Files

nopenuttn — Mon, 30 Jun 2025 17:29:03 GMT

Hello!

Looks like there have been some recent updates made to File Integrity Monitoring. After reviewing the MS documentation here it looks like you can now create custom Rules for Files and for custom Registry keys. From what I can gather from the documentation, agentless scans are used for custom rules that you create and an agentless scan occurs once every 24 hours.

I have created several custom rules to detect if a file has been Deleted, Added, Modified or Renamed and Defender for Cloud is still not detecting any changes. I have made changes to these files 3 days ago, and no changes have been reported back. Any ideas why this might not be working. I have already confirmed that the appropriate RBAC Roles have been assigned to my Key Vaults where CMK Disks are being used.

I also wanted to know if the Agentless FIM can monitor Folders / Directories as well. I haven't seen anything about this in the documentation. Is this even supported?

MISRA support in Defender

yogisrivastava — Tue, 10 Jun 2025 15:10:18 GMT

I want to check for MISRA C code compliance. The idea is to check for MISRA C compliance when asking for a Pull Request. If the code fails on those checks, the PR will not be created. This way, we enforce MISRA compliance before integrating the code to the repository.

I am not seeing MISRA in the list of standards under - Regulatory Compliance>>Subscriptions>> Security Po;icies

Onboarding MDE with Defender for Cloud (Problem)

GuidoImpe — Tue, 03 Jun 2025 06:09:20 GMT

Hello Community,

In our Customer i have a strange problem.

We onboarded with Azure Arc server and activate a Defender for Cloud servises only for Endpoint protection.

Some of this device onboarded into Microsoft Defender portale, but not appears as a device, infact i don't have opportunity to put them into a group to apply policy.

I have check sensor of Azure Arc and all works fine (device are in Azure Arc, are in the defender portal and see them on Intune (managed by MDE)).

From Intune portal

From Defender portal

But in difference from other device into entra ID exists only the enterprise application and not device

I show the example of device that works correctly (the same onboarding method)

Is there anyone who has or has had this problem?

Thanks and Regards,

Guido

Defender for AI data storage/processing

neiltreebeard — Thu, 22 May 2025 16:06:40 GMT

Hi, does anyone know where the data that Defender for AI uses is processed and what data is stored and available to Microsoft?

If abuse monitoring is turned off, the documentation says "Microsoft does not store the prompts and completions associated with the approved Azure subscription."

If content filtering is enabled the documentation says "Noo prompts or generated content are stored in the content classifier models."

https://learn.microsoft.com/en-us/legal/cognitive-services/openai/data-privacy?tabs=azure-portal#preventing-abuse-and-harmful-content-generation

But I was wondering what data is stored/processed, where this happens and if there's any documentation around this for the Defender for AI service.

Could anyone point me to a page, please?

Thanks,

Neil.

Need help with enabling the "Security attack path" export data type in continuous export

Defender for Cloud Inventory API Coverage — No Official Way to Retrieve Per-Resource Coverage?

JuanOJG — Fri, 09 May 2025 13:34:16 GMT

I'm reaching out to the Microsoft Defender for Cloud team and the broader community because I've run into a gap that I believe others may face too — and I’m hoping for guidance or clarification.

I need to programmatically retrieve a list of resources from a subscription and determine if each resource is covered by a Defender for Cloud plan. This would replicate what we see in the Azure Portal under:

Microsoft Defender for Cloud > Inventory:

The goal is to fetch this data via API and replicate that table — but the problem is that it seems there’s no way to retrieve the “Defender for Cloud” coverage status per resource.

Here’s what I’ve tried so far:

The /pricings endpoint — returns plan tiers like Free or Standard, but only for the overall subscription or service type, not individual resources.
Azure Resource Graph — the properties field does not contain any Defender-related indicators that would confirm whether a specific resource is covered.

My Question

Does an API exist today to retrieve per-resource Defender for Cloud coverage?
Is there a /coverage endpoint or equivalent that is officially supported?

If anyone from the Defender for Cloud or Azure product teams can point me in the right direction, I’d truly appreciate it.

Thank you!
