#### Using Advanced Fraud Screening

The sums of fraudulent transactions are typically much greater than normal ones, and you can customize the Advanced Fraud Screen settings and risk thresholds for several amount ranges, depending on your business requirements, industry conditions, and fraud experience.

Note: This fraud control built in the plug-in does not interact with the HSPcomplete Anti-fraud Manager. The fraud thresholds being set here are being just compared with the fraud screening results received after a transaction is checked on the payment gateway side, using their internal fraud screening system. And in case the fraud score produced by the payment gateway exceeds the threshold declared by you in the plug-in configuration form, the payment gateway will reject a transaction.

Configure the CyberSource basics as described earlier in this Guide.

To use the CyberSource advanced fraud screening:

1. Click the Edit button on the plug-in screen.
2. Mark the Enable advanced fraud screening checkbox.
3. Specify the order total sums in the Amount range fields. In the less than field you can type the amount so that all orders with total sum lower than this limit will be checked by the single fraud threshold (for example, lower that $10). In the other fields you can specify the different amount ranges. Finally, in the or more field you can set the amount for all orders with total sum that exceeds this limit will be checked by the single fraud threshold.
4. Specify the fraud thresholds in the Fraud Score Thresholds fields at the relevant amount ranges. The scoring system ranges from 0 to 99, where 0 represents the lowest probability of fraud and 99 represents the highest. For example, if you set the score threshold to 40, orders that score 40 points or fewer are accepted, while orders that score more than 40 points are rejected. Advanced Fraud Screen uses the most restrictive value in the order when calculating the final score. If you do not specify a threshold, Advanced Fraud Screen assumes a default value of 50. If you want all your orders to pass the Advanced Fraud Screen, set the value to 99. Note that if you set the score threshold value greater than 99, Advanced Fraud Screen will automatically adjust the threshold to 80. Please, refer to the CyberSource documentation for more details.
