    • Threat Response - Trigger Response Action
  • The following atomic actions must be imported before you can import this workflow:
    • None
  • The targets and account keys listed at the bottom of the page
  • Cisco Secure Endpoint

Workflow Steps

  1. Make sure the observable is supported
  2. Generate an access token for Threat Response
  3. Fetch available response actions
  4. Check that Secure Endpoint actions are available (if not, end the workflow)
  5. Extract the module instance ID for Secure Endpoint
  6. (Optional) Send an email notification (requires an SMTP Endpoint target)
  7. Create the approval request and wait…
  8. If the request is approved, trigger the response action to isolate the endpoint

Configuration

  • Set the Secure Endpoint Module Name local variable to the name of your Secure Endpoint SecureX module
  • Set the Task Approver local variable to the email address of the SecureX user you want to approve requests from the workflow
  • Set the Task Requestor local variable to the email address of the SecureX user you want to own requests from the workflow
  • If you want the workflow to send emails, you need to:
    • Create an SMTP Endpoint target called SMTP Target for the workflow to use
    • Enable the Send Email activity and customize it as needed
  • If you want to change the name of this workflow in the pivot menu, change its display name
