Cortex XDR Analytics BIOC Rules' Severity

mirtoghrulseyid — Mon, 05 Aug 2024 08:29:10 GMT

I am writing to inquire about the procedure for modifying the severity levels of BIOCs (Behavioral Indicators of Compromise) within the Analytics module of Cortex XDR. Specifically, we are looking to understand how to create or adjust a custom rule where we can manually add a BIOC and select its severity level according to our needs.

Could you please provide guidance or documentation on how to achieve this? Detailed instructions or any relevant steps to create or modify such a rule would be greatly appreciated.

Hi @mirtoghrulseyid

When you created a BIOC rule

In Detection Rules > BIOC > Right click over BIOC rule and select edit

And here you will change the severity

Hi Alejandro_Hernandez,

Thank you for your response. However, what I need to change is not the BIOC itself, but the severity of the Analytics section.

I can show you this picture as an example

Hi @mirtoghrulseyid

Checking the Analytics BIOC rules, here is not possible to modify the severity

The only way to modify is when the alert is generated and set the new severity

Yes..as @Alejandro_Hernandez mentioned it's not possible to edit analytics biocs or BIOCs from source as paloalto.

Instead you can create automation rule and set criteria on alert name or combination of alert names and hosts etc.. the action of the automation can be to change severity. So that when such alert comes in the severity is set as per your requirement.

yes @Fm12345

The automation rule is a good idea

The rule is similar like that
