Only active (i.e., enabled) fraud plug-ins can be used for a rule creation within a fraud filter. Thus, if you are going to add a new rule to a filter and do not see some fraud plug-ins that should be offered for a rule creation, please check whether such plug-ins are currently active.
To activate or disable a fraud plug-in:
Note: To select or unselect all plug-ins in the list, click the box next to the Title field.
Note: A fraud plug-in can also be activated or disabled from a plug-in screen. To this effect, select a plug-in and then click the General Configuration tab. Click the Edit button and check or clear the Active box on a plug-in screen to activate or disable a plug-in respectively. Save changes.
