Data is the new currency, and protecting it is more important than ever. In IBM i environments, safeguarding sensitive information at the database level is a key requirement for compliance, risk reduction, long-term application trust and data consitency. With traditional database methods and additional programming, data access can be restricted, but also circumvented! Db2 for i provides powerful, built-in capabilities for fine-grained security through Row and Column Access Control (RCAC), enabling precise control over which data can be seen and by whom (on user profile and group profile level) —without requiring changes to application code.If RCAC is activated only explicitly registered users can see an access the database data. Even powerful profiles with QSECOFR user classe or *ALLOBJ authority cannot see any data if they are not registered.Since the implemented RCAC rules cannot be circumvented (not even by powerful user profiles) an detailed planning is required, so no data will get lost
