Target while adding Allow/Block list

A.Bisht584260 — Thu, 04 Jul 2024 06:16:06 GMT

Hi Team,

I am not able to select the target machines after adding any Hash value in the "Action center -> Block/Allow List".

What exact type of role it needs to have the option to select the target machines?

Hello @A.Bisht584260 ,

Thanks for reaching out on LiveCommunity!

You cannot scope the endpoints to allow or block the hash from the Action Center as Cortex XDR is not a Application Control tool.

Your use case can be achieved but there are lot of if and else.

To block the hash on the specific EP, you need to use the BIOC to BTP feature. But if the alert count reaches 5000, then the rule will get disable. Please refer to below article and have a look on accepted answer:

To allow hash, you need to use Disable Prevent Rule. But you will still get those alerts.

Hi @aspatil ,

Thanks for your response, actually we had a Official session from the Palo Alto and the tutor was also officially sent by Palo Alto itself.
He showed us in his instance that we can target a number of endpoints accordingly.

Apart from Allow or Block Hash action, in rest of the actions you can scope the target.

Here is the conversation of 2022, where the user was looking for the same .
