RFC connections can be protected using Secure Network Communications (SNC). For more information, see the SAP NetWeaver Security Guide under Transport Layer Security .

Recommendation

We strongly recommend that you use secure protocols (SSL, SNC) where possible.

End of the recommendation.

In addition, there is also an authorization check for calling the RFC-capable function module itself (CALL FUNCTION 'AUTHORITY_CHECK_RFC'). For more information, see SAP NetWeaver Library and choose RFC Programming in ABAP .

For more information about the security of ALE connections, see SAP NetWeaver Security Guide ALE .
