The SAP Gateway and the SNC Interface 

Using the SAP interface SNC (Secure Network Communication) guarantees secure communication.

SNC supports third-party security systems (such as Kerberos, SECUDE, etc.).This provides for a reliable authentication of the partners and secure data transfer.

The SAP Gateway can reject connections that are not based on SNC.

SAP provides a range of SNC parameters. For more information on configuration see:

·        Configuring Support of SNC Components
