Vulnerability discussion

For completeness of forensic analysis, it is necessary to track failed attempts to log on to the DBMS. While positive identification may not be possible in a case of failed authentication, as much information as possible about the incident must be captured.

Check content

Execute the following SQL as enterprisedb: SHOW edb_audit_connect; If the result is not "all" or if the current setting for this requirement has not been noted and approved by the organization in the system documentation, this is a finding.

Fix text

Execute the following SQL as enterprisedb: ALTER SYSTEM SET edb_audit_connect = 'all'; ALTER SYSTEM SET edb_audit_disconnect = 'all'; SELECT pg_reload_conf(); or Update the system documentation to note the organizationally approved setting and corresponding justification of the setting for this requirement.

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.
