Ensure 'IMP_FULL_DATABASE' Is Revoked From Unauthorized 'GRANTEE'

高级别 1自动化oracle-db

说明

The IMP_FULL_DATABASE privilege allows users to import database objects using Oracle Import utility. Unauthorized access to this privilege can lead to data corruption. 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.

修复方法: 操作指南或基础设施补丁

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 IMP_FULL_DATABASE FROM <grantee>; In the case of a grant via a role: REVOKE <rolename> FROM <grantee>;
