Use Secure Network Communication (SNC) for data communications between ServiceNow MID Server and SAP systems.

Secure Network Communication (SNC) is a security feature in SAP systems that confirms that the data transmitted over the network is protected by encryption, authentication, and integrity checks. SNC provides a secure communication pathway between SAP systems and external components, safeguarding sensitive information from unauthorized access, tampering, and eavesdropping.

SNC is used to:

  • Enhance security: By encrypting the data transmitted over the network, SNC helps prevent unauthorized access and confirms confidentiality.
  • Check data integrity: Integrity checks confirm that the data isn't altered during transmission, protecting against tampering.
  • Authenticate communication parties: SNC provides strong authentication methods to verify the identities of the entities involved in the communication.

SNC Architecture

SNC operates within the SAP NetWeaver Application Server (AS) environment. It uses the GSS-API (Generic Security Services Application Program Interface) to integrate with external security libraries and products. Commonly used security libraries include Kerberos-based solutions and SAP's own Secure Login Library (SLL).
