Ensure that 'Test Policy' is selected in the view selection pane on the left-hand side of the configuration dialog. The most straight forward approach while configuring a scan is to enable all the tests and then disable the low value tests which increase the time required to run the scan.
Select 'Enabled/Disabled' from the 'sort tests by' dropdown. First check the 'Partially Enabled' then the 'Disabled' boxes. The only entry displayed should be 'Enabled'. Select 'Severity' from the dropdown. Uncheck the 'Low' and 'Informational' boxes. For the purposes of scanning IEG it is not required to perform invasive tests as these tests are more concerned with testing the platform. Select 'Invasive' from the dropdown. Uncheck the 'Invasive' box.
