TinggiLevel 1Otomatisoceanbase

Deskripsi

The unnecessary privileges should be revoked from default public role to minimize security risks and adhere to the principle of least privilege. Oracle-mode tenant. Passes when PUBLIC holds no system, role or object privileges; any grant that is returned must be justified by organisational need. Runs obclient against an Oracle-mode tenant using the connection options in OB_ORA_CONN (default "-h127.0.0.1 -P2881 -uSYS@oracle"); supply the password via OB_ORA_CONN (-p...) or ~/.my.cnf.
