noun

1. An excess of something beyond what is required or suitable for a given purpose.

Example"So, Bob, are you ready to tear down that fence?" "Yeah, Chuck, the plastic explosives are all wired up!" "Wait a minute Bob, isn’t that an overkill“

Overkill [oh-ver-kil]

PSD2 example"So, Bob, are you ready to expose those 7 API endpoints for PSD2 XS2A?" “Yeah, Chuck, the API Management platform is getting all wired up!" "Wait a minute Bob, isn’t that an overkill“

Don’t Fall for “API Management” Marketing

The Hold ring is for things that are getting attention in the industry, but we don't think are ready for use. Sometimes this is because we don't think they're mature enough yet: sometimes it means we think they're irredeemably flawed. We don't have an "avoid" ring, but we do throw things in the Hold ring that we wish our clients wouldn't use.

Lightweight API gateway with batteries included

API Gateway

Unlike overambitious API gateways, it implements the essential set of API gateway capabilities:

→ Reverse proxy

→ Traffic control with request rate limiting and request size limiting

→ API access protection with JWT, OAuth2 token validation

→ OWASP Top 10 security hardening

→ Logging

→ Health endpoint for SLA monitoring

→ Chargeable activity records for monetization

18

Lightweight API gateway with batteries included

API Gateway

Unlike generic DIY gateways, comes with PSD2 specific plugins:

→ BG API proxy endpoints, hypermedia and header handling

→ SCA integration, flow and exemption rule handling

→ TPP authentication with QWAC based mutual TLS

→ Message signing and validation with eIDAS QSEAL certificates

19

Managing user’s consent to TPP applications

Identity & Access

• OAuth2 and OpenID Connect protocol endpoints

• Provide customers with total control in giving and revoking consents for access to their accounts

• Store customer identity, consent and policy data

• Password credential management flows

• Linking of 2nd factor credentials

• Enrolment of TPP client applications

20

Testing facility for TPP developers

API Sandbox

• Pre-configured endpoints according to Berlin Group specification

• Preloaded set of customers and their accounts data

• CBS simulator for payment transactions and accounts

• Comprehensive test cases as Postman collections

• Hosted on cloud or on-premise

21

Self-service environment for TPP developers

API Developer Portal

• Lean set of features that implement the capabilities essential for PSD2:

→ Documentation content that follows Berlin Group implementation guidelines

→ API catalogue explorer

→ Interactive API console

→ TPP onboarding and self-service

→ OAS 2 (Swagger) API descriptions

22

Reduces effort to connect Berlin Group API endpoints to CBS

Core Banking Connectors

• Connector kit for WSO/2 ESB:

→ Simple integration calls thanks to challenges solved by API gateway

→ Fully implemented integration flows for all APIs that call into simulated core banking stored procedures

→ Integration development service from ASEE

• Pre-built connectors for 3 ASEE core systems

23

Flexibility to authenticate accross channels and devices

2nd Factor Authentication

• Vendor independent, no vendor lock in

• Smooth integration or migration from any hardware token or SMS/OTP pool

• Admin and customer self-management

• Support for variety of hardware and software authentication methods

Hardware tokens EMV card + PCR Mobile token Display card SMS OTP

24

Minimize friction in compliant manner

Mobile Token

• Push message and QR code authentication and transaction signing for reduced friction

• What you see is what you sign

• Mobile SDK for IOS and Android

• Cloning protection

• White label branding

• RASP for separate execution environment, detection of altered software*

* Android from May, IOS from July release

25

Holistic monitoring and prevention with proven fraud detection solution

Fraud Monitoring

• Monitoring authentications, transactions and account activity across channels

• High performance engine for real-time risk analysis and transaction scoring

• Risk factors include geolocation, malware, known fraud
