Vulnerability discussion

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.

Check content

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

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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
