Restrict Access to SYSCAT.COLUMNS

СредњаНиво 1Аутоматскаdb2

Опис

The SYSCAT.COLUMNS view contains all the columns in the database instance. It is recommended that the PUBLIC role be restricted from accessing this view. Counts grants to PUBLIC on SYSCAT.COLUMNS (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.
