Add-on for Microsoft Defender ATP Known As Windows Defender ATP

This TA is updated version of Windows Defender ATP Modular Inputs TA(https://splunkbase.splunk.com/app/4128/)

Features Added:
1. Supports python2 and python3 - default is python.version=python3
Note: If your Splunk Enterprise is running below Version 8, you will see Splunk throwing below message: (tested in version 7.1.10)
Invalid key in stanza [microsoft_defender_atp_alerts] in /Applications/splunk_7_1_10/splunk/etc/apps/TA-microsoft-defender/default/inputs.conf, line 4: python.version (value: python3)
but Add-on works fine.
I recommend comment python.version=python3 in inputs.conf or make use of the old TA mentioned in the beginning.

2. Supports multiple inputs - each input will have their own checkpoint. This is useful if any user wants to collect data from multiple tenants or subscriptions.


Add-on for Microsoft Defender ATP fetches windows security centre alerts from Azure cloud.

Prerequisite :

First you need to enable SIEM integration in Windows Defender ATP. This will give Client ID , Client Secret. These two are required to get the logs in to Splunk.

Release Notes

Version 1.0.1
May 30, 2020

python.version=python3 is added to pass app inspect.
If you install this TA on Splunk versions below 8, you see below error on starting of Splunk.
Invalid key in stanza [microsoft_defender_atp_alerts] in $SPLUNK_HOME/etc/apps/TA-microsoft-defender/default/inputs.conf, line 4: python.version (value: python3).
Invalid key in stanza [admin_external:TA_microsoft_defender_settings] in $SPLUNK_HOME/etc/apps/TA-microsoft-defender/default/restmap.conf, line 10: python.version (value: python3).
Invalid key in stanza [admin_external:TA_microsoft_defender_microsoft_defender_atp_alerts] in $SPLUNK_HOME/etc/apps/TA-microsoft-defender/default/restmap.conf, line 16: python.version (value: python3).

The problems because the parameters which are used to support version 8 are not available in below versions 8. you can ignore these alerts. or you can comment python.version in inputs.conf and restmap.conf

Version 1.0.0
