To change the vulnerability scanner configuration

  1. Navigate to Configuration > Administration > Main.
  2. Click Vulnerability Scanner to display the fields underneath.

  4. Click Update Configuration.

By default, USM Appliance can run five vulnerability scans simultaneously per USM Appliance Sensor. If you configure a new scan job when there are already 5 scans running on the same USM Appliance Sensor, USM Appliance delays the job to for 15 minutes. Should the USM Appliance Sensor has not finished scanning at that time, USM Appliance delays the job for another 15 minutes, until the USM Appliance Sensor is available to start the new scan.

To lower the maximum number of simultaneous scans

  2. Double-click the USM Appliance Sensor you want to change.
