Hello,
Looking to set up FIM using the Cortex XDR agent and from what I have found so far, it seems unsupported. Has anyone set up FIM using any method?
The only possible option I have found so far is maybe using an auditbeat with the FIM module:

Hi @Optimizer , thanks for writing to Live Community.
You are correct, the way to use File Integrity Monitoring with XDR is through BIOC rules, correlations and reports based on XQL.
Please see a few examples below:
1. XQL Based Correlation Rule : Monitor /etc/, usr/local/share/, /usr/share/ for any conf file modifications:

Looking into this further. BIOC rules seem to be what I'm looking for, but I am not certain how to set my specific file paths I want to be monitored.
When I test creating my own BIOC rule, I cannot find the files I am looking for in the provided list

I finally got around to working on this, and... still need to configure some more, but it works.
dataset = xdr_data |filter event_type = FILE and (event_sub_type = FILE_CREATE_NEW or event_sub_type = FILE_WRITE or event_sub_type = FILE_REMOVE or event_sub_type = FILE_RENAME )
|filter action_file_path in ("C:\Program Files (x86)\*","C:\Program Files\*","C:\ProgramData\*") and action_file_name contains ".exe"
|fields agent_hostname, agent_ip_addresses , action_file_name, action_file_path, action_file_type

Hi Optimizer,
I'm looking for a solution to meet the 11.5 (FIM) requirement of PCI. Did Cortex XDR BIOC meet your FIM requirements?

Dear all,
I'm looking for FIM on Linux (etc/shadow), for the examples are the difference (object before and after) and then the process name like "/usr/sbin/sshd" or "/usr/sbin/userdel". How to show it on XQL Query? Thanks
