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 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 \(SLL\).
