Configure SCOM to monitor changes to security groups

The security team have a new audit requirement to monitor changes to critical AD groups (Domain Admins etc). Does the AD MP monitor this, and if not does anyone know how I could configure SCOM to do so?

We’ve been using a simple Eventlog Rule for critical groups adds / removes. Targeted at Active Directory Domain Controller Computer Role (or a specific DC):

Log: Security

Expression:

AND

EventID Equals 4728 (for Adds — 4729 for Removes)

OR GROUP

Parameter 3 Equals Group1

Parameter 3 Equals Group2

etc

I’m struggling with how to present this data in Squared UP. Has anyone figured out the right criteria in a tile to display for example when someone gets added to the domain admins group? I’ve confirmed the alerts are in the SCOM DW using a SQL query as eventids 4728. I tried this but it’s showing nothing:

 

AlertParams LIKE ‘%CORPORATE\Domain Admins%’ OR Description LIKE ‘%CORPORATE\Domain Admins%’

 

even tried:

 

(AlertParams LIKE ‘%CORPORATE\Domain Admins%’ OR Description LIKE ‘%CORPORATE\Domain Admins%’) AND (AlertParams LIKE ‘%4728%’ OR Description LIKE ‘%4728%’ )
