Secure Network Communication (SNC) in SAP systems provides three key levels of security protection: Authentication, Privacy, and Integrity. Authentication ensures that the communicating parties, such as users or systems, are verified as legitimate, preventing unauthorized access. Privacy protects data during transmission by encrypting it, safeguarding sensitive information from interception or eavesdropping. Integrity ensures that data is not altered or tampered with during transmission, guaranteeing that the received data matches the sent data. These protections are critical for secure communication in SAP environments, particularly for external interfaces or remote connections. Availability, while important, is not a direct function of SNC, as it relates to system uptime rather than communication security. Authorization, which controls access rights, is managed by SAP’s authorization framework, not SNC. By implementing SNC, SAP systems achieve a robust security posture for network communications, ensuring trust and data protection across distributed landscapes.
