Ensure 'CREATE LIBRARY' Is Revoked From Unauthorized 'GRANTEE'

CaoCấp 1Tự độngoracle-db

Mô tả

The Oracle database CREATE LIBRARY privilege allows the designated user to create objects that are associated with the shared libraries. Unauthorized grantees should not have that privilege. Counts non-Oracle-maintained users and roles holding the privilege directly or through a role chain (CDB_SYS_PRIVS / CDB_ROLE_PRIVS); 0 is required, so every approved grantee must be reviewed and documented as an exception. Run on the database host as the Oracle software owner with ORACLE_HOME, ORACLE_SID and PATH set; connects to the CDB root with 'sqlplus -S / as sysdba' (OS authentication) so CDB_/GV$ views cover all open PDBs.

To remediate this setting, execute the following SQL statement, keeping in mind if this is granted in both container and pluggable database, you must connect to both places to revoke. Please ensure proper impact analysis is done before revoking the privilege from a role. REVOKE CREATE LIBRARY FROM <grantee>; In the case of a grant via a role: REVOKE <rolename> FROM <grantee>;
