Restrict Access to SYSCAT.AUDITUSE

MoyenneNiveau 1Automatiséedb2

Description

The SYSCAT.AUDITUSE view contains database audit policy for all non-database objects, such as authority, groups, roles, and users. It is recommended that the PUBLIC role be restricted from accessing this view. Counts grants to PUBLIC on SYSCAT.AUDITUSE (SYSCAT.TABAUTH); 0 is required. Database-level check: set DB2DBDFT to the database name to audit (the rule connects to it with the instance owner's credentials and fails when DB2DBDFT is unset). Run as the instance owner (or with sqllib/db2profile sourced) so the db2 CLP reads this instance's configuration.
