Ensure The Use Of SYS* Privileges Is Audited

YüksekDüzey 1Otomatikoracle-db

Açıklama

The usage of the SYS* (SYS, SYSKM, SYSBACKUP, SYSRAC, SYSDG, PUBLICSYS, SYSKM, SYSBACKUP, SYSRAC, SYSDG, PUBLIC) privileges should always be audited. Under Oracle classic auditing, this was the case with the parameter AUDIT_SYS_OPERATIONS = TRUE. To achieve the same behavior with Unified Auditing, it is necessary to audit all users who use SYS* privileges. As the SYS* privileges have the ... PUBLIC stands for SYSOPER in unified audit policies. Default: Empty 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.
