Understanding CA Risk Authentication Scoring

For each risk evaluation request from your application, CA Risk Authentication executes Evaluation Rules to generate a Risk Score (or Score). This Score is typically a value from 0 through 100 that maps to a recommended Risk Advice (or Advice.) CA Risk Authentication then uses the Scoring Engine to generate the final Score and the corresponding Advice.

The following table explains the mapping between the pre-defined score value ranges and the corresponding Advice.

Note: A score of 0 is assigned to rules that must be executed but not used for scoring. If the score is set to 0, the Advice generated is SILENT.

Score Value (From)	Score Value (To)	Advice	Default Recommended Action
1	30	ALLOW	Allow the transaction to proceed.
31	50	ALERT	Take an appropriate action. For example, if the user name is currently unknown, then on getting an alert you can either redirect it to a CSR or you can create a user in CA Risk Authentication.
51	70	INCREASEAUTH	Perform additional authentication before proceeding any further.
71	100	DENY	Deny the transaction.

You can configure CA Risk Authentication scoring to meet your business requirements by using the Rules and Scoring Management page. For more information, see "Configuring Out-of-the-Box Rules".
