  2. Enter a unique profile name within 63 alphanumeric characters. You can use special characters such as _ and -.

  6. Enable the Fallback options log toggle button to log the request if no threat is detected.
  7. In the Verdict timeout text box, enter the duration for which the device must wait for a response from Juniper Security Director Cloud.
  8. To store DNS requests in cache, enable the Cache TTL toggle button and enter the duration for which requests from benign and command-and-control (C2) domains must be stored.
