Manage File Execution

You can manage file execution on your endpoints using file hashes included in your allow and block lists. If you trust a certain file and know it to be benign, you can add the file hash to the allow list and allow it to be executed on all your endpoints regardless of the WildFire or local analysis verdict. Similarly, if you want to always block a file from running on any of your endpoints, you can add the associated hash to the block list. Adding files to the block list or allow list takes precedence of any other policy rules that may have otherwise been applied to these files. In the
Action Center
in Cortex XDR, you can monitor block list and allow list actions performed in your networks and add/remove file from these lists.
  1. Log in to Cortex XDR.
    Go to
    Response
    Action Center
    + New Action
    .

    In the next heart beat, the agent will retrieve the updated lists from Cortex XDR.
  6. You are automatically redirected to the
    Block List
    or
    Allow List
    that corresponds to the action in the
    Action Center
    .
  7. To manage the file hashes on the
    Block List
    or the
    Allow List
    , right-click the file and select one of the following:
