Summary :
This SAP Note addresses the need for encryption and data integrity in data traffic between SAP applications and Oracle databases, specifically using Oracle's Advanced Security Option (ASO). ASO provides multiple algorithms for network encryption (including AES, RC4, and DES in various key sizes) and two main crypto-checksumming procedures for data integrity (SHA-1 and MD5). The note stresses the importance of configuring both encryption and data integrity checks to protect data from unauthorized access and corruption. Encryption options and crypto-checksumming can be customized in the Oracle Net Services parameter file, `SQLNET.ORA`, under specific parameters for both client and server settings, with recommended settings for environment types like Real Application Clusters (RAC) and different SAP stack configurations. Additionally, licensing requirements and Oracle database version prerequisites are outlined for the implementation of ASO.
