Default Rules in OneSpan Risk Analytics for Digital Banking

OneSpan Risk Analytics for Digital Banking is pre-configured with a number of default rules and factors for digital banking applications to:

• Prevent different types of fraud attacks such as account takeover or phishing attacks.

• Handle session anomalies.

• Manage risks for several kinds of digital banking events such as changing profiles, managing beneficiaries, and tracking fund transfers.

The digital banking template also includes rules to comply with Regulatory Technical Standards (RTS) requirements under PSD2. These pre-defined default rules and factors apply to both non-monetary events and transactions.

The OneSpan Risk Analytics for Digital Banking rules provided in Risk Analytics are based on information provided for each event, and on aggregation factors computed in real time. The factors also provide the necessary features for the machine learning component to score events and transactions. Machine learning models are part of the Decision Analytics Server which aggregates the event data and scores it in real- or near-time. The Decision Engine handles the rules that are processed inside the Oracle Database, executes them, and triggers the actions.

To view, configure, and extend the default digital banking rules of Risk Analytics to your application flows, navigate to the Design Rules & Actions page in OneSpan Risk Analytics Presentation Service.

The following articles list the details of these default rules and factors to handle these tasks.
