#### Setting Default Threshold Score for a Filter and Default Score for Rules

Setting the default threshold score for anti-fraud filters allows avoiding situations when a filter score appears to be set to zero, so a filter moves an order being checked into the Documents for Approval queue if an order fraud score was increased even by a single point.

The default score for rules used in anti-fraud filters pre-fills the corresponding field in a rule configuration form, on rule creation, so you can leave the default score or adjust it.

To set the default threshold score for anti-fraud filters and default score for fraud checking rules:

1. Click Setup on the Anti-Fraud Manager submenu. The form showing the current fraud system state appears on the screen
2. Click the Edit button and adjust the settings:
   1. Enter the default threshold score for all anti-fraud filters into the Default threshold field.
   2. Type the default score for all fraud checking rules into the Default score field.
3. Click the Update button.

#### Setting Fraud Filter Threshold Score

Note: The zero threshold value for a filter means that if at least one rule in a filter scores points to an order during checking, an order that comes through a filter will be automatically rejected and placed into the Documents for Approval queue. So please, configure fraud filters threshold score properly.

To set a fraud filter threshold score:

1. Select a fraud filter by clicking on its title.
2. Select the General Configuration tab from the set of a filter properties that appears on the screen.
3. Click the Edit button.
4. Type the threshold score into the Threshold field of the form that appears on the screen.
5. Click the Update button.

#### Composing Rules for Fraud Filter

The list of rules in a fraud filter is shown under the Rule's Table tab of a fraud filter properties. The list of rules displays the following:

- Title. A rule alphanumeric identifier that does not affect a rule functionality, it is just for your reference. You can assign a rule name while creating or rename a rule later, at any moment.
- Plugin. The fraud plug-in used in a rule. The fraud plug-in can be selected for a rule once and for all, while creating a rule. If you want to use another plug-in in a fraud filter, you should create a new rule that uses this plug-in. If you do not want to use a fraud plug-in in a filter, then either deactivate a rule or delete it.
- Active. Shows whether a rule is used for fraud check (active) or not. Green tick means that a rule is active and used for checking, red cross means that a rule is currently disabled and thus is ignored and do not used for checking. You can activate or disable a rule at any moment, by editing a rule properties.
- Action. An action to be performed in case a rule condition is fulfilled, i.e., a fraud plug-in response corresponds to a rule condition. One of the following actions can be assigned to each rule in a fraud filter:
  - Alert. In case a rule condition is fulfilled, fraud points defined by you for a rule will be scored to an order and in case after this an order total fraud score exceeds a filter threshold score, such an order will be put in the Documents for Approval queue, otherwise, an order passes to the next rule (if any) in a filter.
  - Reject. In case a rule condition is fulfilled, an order will be put in the Documents for Approval queue immediately without respect to an order total score.
  - Bonus. In case a rule condition is fulfilled, fraud points defined by you for a rule will be taken from an order score, so an order total score will be decreased and such an order will get more chances to pass through the fraud check.
- Score. The number of points being scored t or taken from an order depending on an action se for a rule.

1. Select a filter.

   Note: It is possible to select only one fraud plug-in per rule.

5. Click the Next button.
6. Adjust the rule configuration by filling the form that appears:
   1. You can enter a rule name into the Title field. By default, this field is pre-filled with the name of the condition you have selected on the previous step. You can leave the default title or type another name you consider more convenient.
   2. From the Action drop-down menu, please select an action to be performed in case a fraud plug-in response corresponds to the condition selected. Please note that actions differ depending a condition selected. For example, if you have selected the condition like "Customer e-mail is in the Black List" (which means that fraud is quite possible) you will be offered to select either Alert or Reject action. If you select the condition like "Customer phone number is not in the Black List" (which means that an e-mail is OK), you will be offered to select the Bonus action.
   3. Enter the number of points to be scored to or taken off an order depending on the rule condition fulfillment into the Score field.

      Note: The corresponding fraud filter threshold score is shown below the Score field. Please, set the rule score accordingly.

   4. To use the check defined by the rule, check the Active box. If the Active box remains clear, the rule will be not used for the chain of checks defined for the filter.
