Incident Mirroring

Mirroring In (Microsoft 365 Defender → XSOAR)

When incidents are mirrored into XSOAR from Microsoft 365 Defender:

1. Comments mirrored from Microsoft 365 Defender will be added to the incident as entries in XSOAR and tagged with the Comment Entry Tag From Microsoft 365 Defender.

   • By default, the tag is set to: CommentFromMicrosoft365Defender.

2. If an incident is closed in Microsoft 365 Defender (status = Resolved) and Close Mirrored Cortex XSOAR Incidents is enabled:

   • The "classification" field in Microsoft 365 Defender will be mapped to the Close Reason field in XSOAR.

Mirroring Out (XSOAR → Microsoft 365 Defender)

When incidents are mirrored out from XSOAR to Microsoft 365 Defender:

1. Supported Fields:
   The following fields are mirrored:

   • Microsoft 365 Defender Status
   • Assigned User
   • Microsoft 365 Defender Classification
   • Microsoft 365 Defender Tags

2. Comments:

   • XSOAR entries with the Comment Entry Tag To Microsoft 365 Defender tag are mirrored as comments in Microsoft 365 Defender.
   • Note: Comments cannot be edited or deleted in Microsoft 365 Defender, as this functionality is not supported.

3. If an incident is closed in XSOAR and Close Mirrored Microsoft 365 Defender Incidents is enabled:

   • The Close Reason field is mirrored to the status, classification and determination fields in Microsoft 365 Defender.

Closing Logic

Incoming Closing Logic (Microsoft 365 Defender → XSOAR)

When an incident is resolved in Microsoft 365 Defender:

1. If the status = Resolved:
   • The "classification" field will be mapped to the Close Reason field in XSOAR using the Close Reason Mapping Table.
   • The "classification" and "determination" fields will be mirrored into the Microsoft 365 Defender Classification field in XSOAR.

Example:

• An incident closed in Microsoft 365 Defender with:

  • status = Resolved
  • Classification = True Positive
  • Determination = Phishing

  Results in XSOAR:

  • Close Reason = Resolved
  • Microsoft 365 Defender Classification = True Positive - Phishing

Close Reason Mapping Table (Incoming):

Classification in Microsoft 365 Defender	Close Reason in XSOAR
Not set	Other
True Positive	Resolved
False Positive	False Positive
Informational / Expected Activity	Resolved

Outgoing Closing Logic (XSOAR → Microsoft 365 Defender)

Disclaimer: The closing form currently does not support the Microsoft 365 Defender Classification field, and False Positive Classification is not yet enforced when selecting "False Positive" as the close reason. If classification is required, please manually update the Microsoft 365 Defender Classification via the layout before closing the incident.

When closing incidents from XSOAR to Microsoft 365 Defender, the following logic is applied to map the Close Reason field:

1. General Status Update:
   When an incident is marked as closed in XSOAR, the status field in Microsoft 365 Defender will always be set to Resolved.

2. Close Reason: Resolved or False Positive
   If the Close Reason in XSOAR is Resolved, the Microsoft 365 Defender Classification field is mirrored to classification and determination fields as-is into Microsoft 365 Defender without any changes.

3. Close Reason: Other or Duplicate
   If the Close Reason in XSOAR is either Other or Duplicate, the following updates occur:

   • classification → Unknown
   • determination → NotAvailable

Close Reason Mapping Table (Outgoing):

Close Reason in XSOAR	Classification in Microsoft 365 Defender	Determination in Microsoft 365 Defender	Status in Defender
Resolved	Mirrored as-is	Mirrored as-is	Resolved
FalsePositive	FalsePositive	Mirrored as-is \ Other	Resolved
Other	Unknown	NotAvailable	Resolved
Duplicate	Unknown	NotAvailable	Resolved

Notes

1. Configuration Requirements for Closing Incidents:
   To close incidents in both directions, ensure the following settings in XSOAR:

   • Close Mirrored XSOAR Incident checkbox = True
   • Close Mirrored Microsoft 365 Defender Incident checkbox = True

   If these checkboxes are False, only the Microsoft 365 Defender Status and Microsoft 365 Defender Classification fields will be updated, and incidents will not be closed.

Configure Incident Mirroring

This feature is compliant with XSOAR version 6.0 and above.
When mirroring incidents, you can make changes in Microsoft 365 Defender that will be reflected in Cortex XSOAR, or vice versa.

The following instructions include steps for configuring the integration and incoming and outgoing mappers. However, they do not cover every option available in the integration nor classification and mapping features. For information about classification and mapping see Classification and Mapping.

Note:

• For Cortex XSOAR version 6.1 only, the final source of truth for an incident are the values in Cortex XSOAR. For example, if you change the severity in Cortex XSOAR and then change it back in Microsoft 365 Defender, the final value that will be presented is the one in Cortex XSOAR. For versions 6.2 and later, if mirroring is in both directions then the latest update is the source of truth.
• The mirroring settings apply only for incidents that are fetched after applying the settings.
• To use a custom mapper, you must first duplicate the mapper and edit the field in the copy of the mapper. If you detach the out of the box mapper and make changes to it, the pack does not automatically get updates.

STEP 1 - Configure the Microsoft 365 Defender Integration Instance for Mirroring.

1. Navigate to Integrations and search for Microsoft 365 Defender.
2. Click Add instance.
3. Select Fetches incidents.
4. Select the Incident Mirroring Direction:
   • Incoming - Mirrors changes on the Microsoft 365 Defender incident in to the Cortex XSOAR incident.
   • Outgoing - Mirrors changes on the Cortex XSOAR incident to the Microsoft 365 Defender incident.
   • Incoming And Outgoing - Mirrors changes both in and out on both incidents.
5. Under Incident type, select Microsoft 365 Defender Incident.
6. Under Mapper (incoming), for default mapping select Microsoft 365 Defender - Incoming Mapper. For custom mapping, follow the instructions in STEP 2 and then select the custom mapper name.
7. Under Mapper (outgoing), for default mapping select Microsoft 365 Defender - Outgoing Mapper. For custom mapping, follow the instructions in STEP 3 and then select the custom mapper name.
8. Enter the relevant Comment Entry Tag To Microsoft 365 Defender and Comment Entry Tag From Microsoft 365 Defender values.
   These values are mapped to the dbotMirrorTags incident field in Cortex XSOAR, which defines how Cortex XSOAR handles comments when you tag them in the War Room. Note:
   These tags work only for mirroring comments from Cortex XSOAR to Microsoft 365 Defender.
9. To enable mirroring when closing an incident in Cortex XSOAR and Microsoft 365 Defender, select the Close Mirrored Cortex XSOAR Incidents and Close Mirrored Microsoft 365 Defender Incidents checkboxes respectively.
10. Click Save & Exit.

STEP 2 (Optional) Configure the Incoming Mapper by Incident Type

Note: Any modifications require that the mappers be cloned before any changes can be applied.

1. Navigate to Classification and Mapping and for Incidents search for the Microsoft 365 Defender - Incoming Mapper.
2. Select it and click Duplicate.
3. Under the Incident Type dropdown, select Microsoft 365 Defender Incident.
4. Verify the mapper has these fields mapped. They will pull the values configured on the integration instance settings at the time of ingestion.
   • dbotMirrorId - dbotMirrorId - the field used by the third-party integration to identify the incident. This should be the incidentId of the Microsoft 365 Defender Incident.
   • dbotMirrorDirection - determines whether mirroring is incoming, outgoing, or both. Default is Both. This should match the instance configuration.
   • dbotMirrorInstance - determines the Microsoft 365 Defender instance with which to mirror. This should match the instance configuration.
   • dbotMirrorLastSync - determines the field by which to indicate the last time that the systems synchronized.
   • dbotMirrorTags - determines the tags that you need to add in Cortex XSOAR for entries to be pushed to Microsoft 365 Defender. They should be copied from the tags in the instance configuration. These are also the tags that must be put on the War Room record in order for it to sync.

STEP 3 - Modify the Outgoing Mapper

Note:
Any modifications require that the mappers be cloned before any changes can be applied.

1. Navigate to Classification and Mapping, and for Incidents search for the Microsoft 365 Defender - Outgoing Mapper.
2. Select it and click Duplicate.
   The left side of the screen shows the Microsoft 365 Defender fields to which to map and the right side of the screen shows the Cortex XSOAR fields by which you are mapping.
3. Under the Incident Type dropdown, select the relevant incident type (for example Microsoft 365 Defender Incident).
4. Under Schema Type, select incident. The Schema Type represents the Microsoft 365 Defender entity that you are mapping to.
5. On the right side of the screen, under Incident, select the incident based on which you want to match.
6. Change the mapping according to your needs, including any fields you want mapped outward to Microsoft 365 Defender.
7. Save your changes.

STEP 4 - Create an Incident in Microsoft 365 Defender

For purposes of this use case, it can be a simple incident. The new incident will be ingested in Cortex XSOAR in approximately one minute.

STEP 5 - Add a Comment from Cortex XSOAR to Microsoft 365 Defender

In the example below, we have written A comment from Cortex XSOAR to Microsoft 365 Defender.

1. Create an entry in the incidents' war room.
2. Click Actions > Tags and add the Comment Entry Tag To Microsoft 365 Defender tag.
3. Navigate back to the incident in Microsoft 365 Defender and within approximately one minute, the changes will be reflected there, too. The note is mirrored out as a comment in Microsoft 365 Defender.
   You can make additional changes like closing the incident or changing the assignee and those will be reflected in both systems.

Commands

You can execute these commands from the Cortex XSOAR CLI, as part of an automation, or in a playbook. After you successfully execute a command, a DBot message appears in the War Room with the command details.
