Exclusion process cortex?!

[tlmarques]

Hi,

How can I create an exclusion in Cortex XDR  to stop it from scanning a specific executable??

We have a critical software in our company, and we've noticed that Cortex is constantly analyzing it, causing the machine high CPU and MEM.

How can we exclude this file from the analysis? We want to maintain protections such as Ransomware, just excluding the process monitoring.
It's possible?

Hi @tlmarques, thanks for reaching us using the Live Community.

You need to create a Disable Prevention Rule.

Go to Settings - Exceptions Configuration - Disable Prevention Rules, create a new one, set the name and fill the parameters:

- Set the target properties, folder location and executable name, command line, or you can use the signer. Only one is enough.

- Module: try with the Local Analysis and check how it goes, if it is an in-house software it is probably "Unknown" for Wildfire and the agent tries to analyze it locally, consuming CPU and RAM to do it.

- Scope: select the applied profile to the Endpoints with the issue.

You can also go to Detecion Rules - IOC and add an IOC with the application path and/or executable hash (ni the "Type" field):

Let me know how it goes.

If this post solved your question, please mark it as the solution.

Hi,

I found your response very insightful and helpful. I just have a question. How can I know which module to select when creating that prevention profile? In my case, it's also an in-house developed software which its developer reported performance issues. For example, should I select "Wildfire" and "Behavioral Threat Protection" together, or just one of them suffices? How can I find which module(s) is/are more relevant to this performance issue?
