They demonstrate the configuration in SAP Integration Suite and SAP SuccessFactors. While the two blogs linked before are describing this step by step for SAP Integration Suite, you can find here an example flow and the video below. What can you do to make APIs calls more secure?įor a more secure communication oAuth with SAML Bearer Assertion was introduced in SAP SuccessFactors and in the SAP Integration Suite Connector for OData and SOAP APIs. In order to configure it in a connector, at least one person has to enter it and is aware of it. The same is true for the visibility of the password. Passwords are long living and everybody who knows it can access the system. If a secure connector is used, like the SuccessFactors Connector in SAP Integration Suite, there is no point in time where any person would have access to the secret (private key) used to generate the SAML assertion.īoth are not true for Basic Authentication when API users and passwords are being used.SAML Assertions as well as the Access Tokens have a short living validity, hence even if they are exposed they can not be used at all or not for long.Why is oAuth2 with SAML more secure than the existing Basic Authentication used so far? There are two major answers to this questions: The new authentication mechanism is oAuth2.0 with SAML Bearer Assertion.
In 2021 a set of new and more secure authentications mechanisms have been released for SAP SuccessFactors OData and SOAP APIs as well as for the corresponding SAP Integration Suite and Boomi connectors. This is even more true for integrations and API based communication. It’s a constant process of adjusting the existing security concepts to newest attack vectors and apply state of the art responses to those.

In the meantime everybody should know that security is one of the most important aspects when it comes to run software in the cloud and that security is never something which is “done”.
