Cortex XDR block file execution based on ico\file name

Hi,

I've been wondering - Is it possible to block the execution of a file by file name or ioc in the xdr?

It sounds like a rather basic feature yet i can't seem to find anything about it in the docs - only thing i found is block file execution based on hash

This question is for Cortex XDR/Traps categories not for here. From what I seen for example even in other endpoint systems like Microsoft defender extensions and hashes are used and not the file names. Maybe only URL filtering or file path can be used for something like that:

Add a New Restrictions Security Profile (paloaltonetworks.com)

Cortex XDR/Traps in itself does not support URL filtering like the Microsoft Defender custom indicators but the firewall can do this as it's job:

Maybe endpoint DLP can do what you want like Digital Guardian etc. as blocking a file name is more like DLP task than EDR/Endpoint protection systems.

Maybe see this as I just found it and it is a new article for the XDR using the Restriction profile:
