Use

The security requirements for RCF and ICF communications can be split into four basic scenarios:

  • RFC communication between SAP systems (ABAP)

  • RFC communication with external (non-SAP) systems

  • ICF communication between SAP systems (ABAP)

  • ICF communication with external (non-SAP) systems

Note

The additional security recommendations for the RFC scenario Communication with External Systems in this guide make particular reference to cases where an external system is used as a server (SAP calls the external system). If you use an external system as a client (the external system calls SAP), the appropriate SAP-specific security mechanisms are implemented on the SAP side.

Note

Remember that the required security settings may vary according to which scenario you use.
