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 enables you to:

* Enhance security: By encrypting the data transmitted over the network, SNC helps prevent unauthorized access and helps protect 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 {#erpc-use-an-snc-connection-in-erp-canvas__section_npq_fyz_12c}

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