Enabling Secure Network Communication for SAP S/4 HANA Integration
Secure Network Communication (SNC) is an application layer in SAP S/4 HANA that provides an interface to an external security product.
To secure RFC connections between SAP S/4 HANA and SAP Integration Framework 2.0, use SNC with the SAP Cryptographic Library as the external security product.
The following sections describe the steps that enable SNC for RFC connections in SAP S/4 HANA and in SAP Integration Framework 2.0.

Terminology and Abbreviations
Credentials
Credentials are user or component-specific information that allows users or components to access their security information. The credentials may be located, for example, in a protected file in the file system. They often have a limited life span. For example, users’ credentials may be created when they log on to the security product and deleted when they log off.
Personal Security Environment (PSE)
Secure location where a user or component's public-key information is stored. The PSE for a user or component is typically located in a protected directory in the file system or on a smart card. It contains both the public information (public-key certificate and private address book) as well as the private information (private key) for its owner. Therefore, only the owner of the information should be able to access his or her PSE.
For example, the SAP Security Library (SAPSECULIB) stores the application server's information in a PSE. In this case, the PSE contains both the private address book for the SAP System as well as the SSF profile.
