Assign multiple risk objects in Risk Analysis

How to assign multiple risk object fields and object types in Risk analysis response action. I know it's possible from search using appendpipe and sendalert but we want this to be added from the response action.

Example as below:

Risk Score - 20

Risk Object Field - user, ip, host

Risk Object Type - System, user

In your correlation search create a fields risk_object and risk_object_type containing your values and have one row per risk entry you want to create. You can also give each row a different risk score if you want to. This example shows how you can use those fields.

In the configuration dialog, just leave the risk object and type fields blank. If you include a score field in the row, it will use that instead.

Hi @bowesmana, Passing blank values in the response action and adding scores to the eval helped me a lot. Thanks for your quick help.

Search example I used:

| makeresults
| eval field_user="noob", field_ip="8.8.8.8", field_host="machine"
| eval risk_object=if(isnotnull(field_host),field_host,null()),risk_object_type=if(isnotnull(field_host),"system",null())
| appendpipe
[| eval risk_object=if(isnotnull(field_user),field_user,null()),risk_object_type=if(isnotnull(field_user),"user",null())]
| appendpipe
[| eval risk_object=if(isnotnull(field_ip),field_ip,null()),risk_object_type=if(isnotnull(field_ip),"system",null())]
| eval risk_score=20
| fields - _time field_user field_ip field_host

The easyest way is to upgrade your Enterprise Security to 6.4, which has the option to add multiple risk analysis to the same result.

Thanks @MaverickT. We came to know about this later and asked our admins to upgrade.
