Custom Alert in XSIAM for Azure AD User Group Changes

[easupport-14217]

Hello,

I was wondering if someone could help point me in the right direction for setting up a custom alert in XSIAM when a user is removed from Azure AD from a particular user group.

For example, let's say we have a user group that excludes MFA-MDM for certain users, and we want to be alerted anytime someone is removed from that group within Cortex via an e-mail alert sent out.

We have the O365 integration set up and actively receive data from Azure AD.

I'm just not sure what type of query I need to do to check for this information to build an alert.

Thanks!

Hi Easupport-14217,

These activities are logged in the msft_azure_ad_audit_raw dataset, you can search for events by filtering for activityDisplayName is "Remove member from group" or "Add member to group".  From there you'll just need to extract event details from targetResources to determine the group and the user.
