| Description |
| When standard auditing is in use, the AUDIT_SYS_OPERATIONS parameter is used to enable auditing of actions taken by the user SYS. The SYS user account is a shared account by definition and holds all privileges in the Oracle database. It is the account accessed by users connecting to the database with SYSDBA or SYSOPER privileges. |

| For Unified or mixed auditing, from SQL*Plus: select count(*) from audit_unified_enabled_policies where entity_name = 'SYS'; If the count is less than one row, this is a finding. For Standard auditing, from SQL*Plus: select value from v$parameter where name = 'audit_sys_operations'; If the value returned is FALSE, this is a finding. |
| Fix Text (F-74474r1064897_fix) |
| For Standard auditing, from SQL*Plus: alter system set audit_sys_operations = TRUE scope = spfile; The above SQL*Plus command will set the parameter to take effect at next system startup. If Unified Auditing is used, to ensure auditable events are captured: Link the oracle binary with uniaud_on, and then restart the database. Oracle Database Upgrade Guide describes how to enable unified auditing.
