----------------
SAP Cloud SOAP Adapter:
First Priority: Client Certificate Authentication
Second Priority: OAuth 2.0 Authentication
Third Priority: Basic Authentication
Explanation:
Client Certificate Authentication provides strong security and is well-suited for protecting SOAP services in SAP Cloud Integration.
OAuth 2.0 Authentication offers flexibility and token-based security, suitable for scenarios involving user authentication or access delegation.
Basic Authentication is considered less secure but may be acceptable for non-sensitive integrations or when other methods are not feasible.
SAP Cloud IDoc Adapter:
First Priority: Client Certificate Authentication
Second Priority: OAuth 2.0 Authentication
Third Priority: Basic Authentication
Explanation:
Client Certificate Authentication ensures secure communication for IDoc exchanges, especially in scenarios involving sensitive business data.
OAuth 2.0 Authentication provides token-based security, which may be suitable for integrating with IDoc services while offering flexibility and scalability.
Basic Authentication can be considered as a fallback option for less sensitive integrations.
SAP Cloud OData Adapter:
First Priority: OAuth 2.0 Authentication
Second Priority: Client Certificate Authentication
Third Priority: Basic Authentication
Explanation:
OAuth 2.0 Authentication is commonly used for securing OData services in SAP Cloud Integration, providing token-based authorization and user authentication capabilities.
Client Certificate Authentication offers strong security for protecting OData endpoints and ensuring secure communication.
Basic Authentication may be used as an alternative, but it's less recommended due to security concerns.
SAP Cloud HTTP Adapter:
First Priority: OAuth 2.0 Authentication
Second Priority: Client Certificate Authentication
Third Priority: Basic Authentication
Explanation:
OAuth 2.0 Authentication is preferred for securing HTTP-based integrations, offering token-based security and access control.
Client Certificate Authentication enhances security for HTTP communications, especially in scenarios requiring mutual authentication.
Basic Authentication may be considered as a fallback option for legacy systems or non-sensitive integrations.
SAP Cloud XI (Exchange Infrastructure) Adapter:
First Priority: Client Certificate Authentication
Second Priority: OAuth 2.0 Authentication
Third Priority: Basic Authentication
Explanation:
Client Certificate Authentication is commonly used for securing XI communication channels, ensuring secure data exchange within the SAP landscape.
OAuth 2.0 Authentication provides token-based security and authorization capabilities, suitable for scenarios involving XI integration with external systems.
Basic Authentication may be used as a less secure alternative when other methods are not feasible, but it's generally not recommended for XI integrations due to security considerations.
----------------------------------
SAP On-Premise SOAP Adapter:
Client Certificate Authentication: First priority for SOAP adapter authentication due to its strong security features.
OAuth 2.0 Authentication: Second priority, providing token-based authentication and authorization capabilities.
Basic Authentication: Third priority, considered less secure but widely supported for legacy or non-sensitive integrations.
SAP IDoc Adapter:
Client Certificate Authentication: First priority for IDoc adapter authentication, ensuring secure communication with SAP systems.
OAuth 2.0 Authentication: Second priority, offering token-based authentication for enhanced security.
Basic Authentication: Third priority, suitable for non-sensitive integrations or legacy systems lacking support for more secure methods.
SAP OData Adapter:
OAuth 2.0 Authentication: First priority for OData adapter authentication, leveraging token-based authorization for accessing OData services securely.
Client Certificate Authentication: Second priority, providing an alternative method for strong authentication.
Basic Authentication: Third priority, suitable for scenarios where OAuth 2.0 is not supported or feasible.
SAP HTTP Adapter:
OAuth 2.0 Authentication: First priority for HTTP adapter authentication, offering token-based security for accessing HTTP services.
Client Certificate Authentication: Second priority, providing an additional layer of authentication if OAuth 2.0 is not available.
Basic Authentication: Third priority, used when other methods are not supported or required for integration.
SAP XI (Exchange Infrastructure) Adapter:
Client Certificate Authentication: First priority for XI adapter authentication, ensuring secure communication within the SAP landscape.
SAP Single Sign-On (SSO): Second priority, leveraging existing authentication mechanisms within the SAP landscape for seamless integration.
OAuth 2.0 Authentication: Third priority, if applicable and supported for integrating with external systems or cloud services.
