Risk Score and Advice

The Advanced Authentication service evaluates each rule, and returns the score corresponding to the highest-priority rule that returns a negative result. The risk score is then used to generate the corresponding advice, which is returned to the application.

The risk score is an integer from 0 through 100. A high score implies that the chances of fraud are higher. The following are the predefined risk scores and corresponding advices:

• Score Value 0 – 30

  Advice: ALLOW

  Default recommended action: Allow the transaction to proceed.

• Score Value 31 – 50

  Advice: ALERT

  Default recommended action: Take appropriate action. For example, if the user name is unknown, then ALERT advice is generated. In this scenario, the login attempt can be redirected to an administrator or the end user can be prompted to register with the system.

• Score Value 51 – 70

  Advice: INCREASEAUTH

  Default recommended action: Perform additional authentication before proceeding any further.

• Score Value 71 – 100

  Advice: DENY

  Default recommended action: Deny the transaction.
