Configuring the Fraud Protection

Services Filters

This chapter describes how to configure the Fraud Filters for your Payflow account. The

chapter explains a phased approach to implementing the security of transactions. You are not

required to use the approach described in this chapter. However it enables you to fine tune

your use of filters before you actually deploy them in a live environment.

You first make and fine-tune filter settings in a test environment. Then you move to a live

transaction environment to fine-tune operation in an Observe-only mode. Finally, when you

are fully satisfied with your settings, you move to live Active mode to begin screening all live

transactions for fraud.

Filter operation is fully described in Appendix A, “Fraud Filter Reference.”

IMPORTANT:Upon completing the configuration procedures within each of the phases

described below, you must click the Deploy button to deploy the filter settings.

Filter settings take effect only after you deploy them.

Filter setting changes are updated hourly (roughly on the hour). This means

that you might have to wait up to an hour for your changes to take effect. This

waiting period only occurs when you move from one mode to the next.

 Phase 1: Run test transactions in Test mode using test transaction servers

In the test phase of implementation, you configure fraud filter settings for test servers that

do not affect the normal flow of transactions. You then run test transactions against the

filters and review the results offline to determine whether the integration was successful.

Once you are happy with the filter settings, you move to the next phase and the settings that

you decided upon in the test phase are transferred to the live servers.

 Phase 2: Run live transactions on live transaction security servers using Observe mode

When you deploy to Observe mode, the settings that you decided upon in the test phase are

automatically transferred to the live servers.

In Observe mode, the filters examine each live transaction and mark the transaction with

each triggered filter’s action. You can then view the actions that would have been taken on

the live transactions had the filters been active. Regardless of the filter actions, all

transactions are submitted for processing in the normal fashion.

 Phase 3: Run live transactions on live transaction security servers using Active mode

Once you have set all filters to the optimum settings, you deploy the filters to Active mode.

In Active mode, filters on the live servers examine each live transaction and take the

specified action when triggered.

NOTE: Remember that you can test a new filter setting using the test servers at any time

(even if your account is in Active mode), and then, if desired, make an adjustment

to the live filter settings.
