SNC-Protected Communication Paths in SAP Systems

The following components support the use of SNC for connections.

SNC protection only applies to connections that use SAP protocols (dialog, RFC or CPIC) protocols. For Internet protocols, use SSL for protection.

You cannot apply SNC protection to the communication path between your application servers and your database. Therefore, we recommend you keep your application and database servers in a secured LAN that is protected with a firewall and SAProuter (see the graphic below).

Network Area Protected with SNC

You can also use SNC between two SAProuters to build a secure tunnel between networks (see the graphic below).
