Notes de l'éditeur
- PTS DSS - PIN Transaction Security Data Security Standard
- Open Banking is due to become a regulation in Australia (similar to the enforcement of PSD2 regulation in the EU). Therefore, Banks need to be able to securely expose sensitive data through APIs so that third party providers can build new applications that provide a much better user experience to multi-banked customers.
- Incident Reporting Guidelines -set methodology for payment service providers in order to determine whether an operational or security incident should be considered major and, therefore, be notified to the competent authority in the home Member State
- Upto 80% of attacks are based on stolen user credentials… One proof from ancient stories Ali baba and 40 thieves.
- Behavioral factors such as walking style, typing are also considered now as another factor
- Incident Reporting Guidelines -set methodology for payment service providers in order to determine whether an operational or security incident should be considered major and, therefore, be notified to the competent authority in the home Member State

- Exposing APIs can seem to commoditize banks by threatening to take away the sole ownership of customer data that banks so far enjoyed exculsively. However, Banks armed with the correct vision and the technology to achieve that can reap much more benefits from this open banking world. Survey conducted in UK by Accenture showed that consumers prefer Banks to be the ones to provide the 3rd party services as well. If and when Banks can take up that role, they become a rich repository of customer data across multiple banks. They can then use that repository to… Provide better services to their customers (eg:- cashflow management across banks) Provide ‘Insight Sales’ to other businesses. (-> attract new revenue streams)
