How to configure Fraud Management Essentials (FME) rules

To apply and update FME rules to transactions processed through your facility, you can:

1. Sign into NAB Gateway.
2. From the left navigation panel, select Fraud Management.
3. Select Rule Configuration.
4. Select Edit on the right-hand side, to edit rules.

Within Rule Configuration, you can select how each rule is treated. There are four types of rule settings – Review, Reject, Monitor or Disabled. These are used as follows:

• Disabled: This setting will prevent the rule from being applied to any transactions.
• Monitor: This setting allows NAB Gateway to provide you details on whether a transaction would trigger a rule.
• Review: This setting forces a transaction to be manually reviewed before completing processing, you may choose these for types of transactions that are of higher risk.
• Reject: This setting will automatically reject any transactions that trigger the rule selected.

The types of rules available for configuration are listed below.
