SV-76019r1_rule Remote database or other external access must use fully-qualified names.

Vulnerability discussion

The Oracle GLOBAL_NAMES parameter is used to set the requirement for database link names to be the same name as the remote database whose connection they define. By using the same name for both, ambiguity is avoided and unauthorized or unintended connections to remote databases are less likely.

Check content

From SQL*Plus: select value from v$parameter where name = 'global_names'; If the value returned is FALSE, this is a finding.

Fix text

From SQL*Plus: alter system set global_names = TRUE scope = spfile; Note: This parameter, if changed, will affect all currently defined Oracle database links. 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.
