Restrict Access to SYSCAT.CONTROLDEP

SedangLevel 1Otomatisdb2

Deskripsi

The SYSCAT.CONTROLDEP view contains the dependency of a row permission or column mask on some other object. It is recommended that the PUBLIC role be restricted from accessing this view. Counts grants to PUBLIC on SYSCAT.CONTROLDEP (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.
