Vulnerability discussion

Under some circumstances, it may be useful to monitor who/what is reading privilege/permission/role information. Therefore, it must be possible to configure auditing to do this. DBMSs typically make such information available through views or functions.This requirement addresses explicit requests for privilege/permission/role membership information. It does not refer to the implicit retrieval of privileges/permissions/role memberships that the DBMS continually performs to determine if any and every action on the database is permitted.

Check content

Execute the following SQL as enterprisedb: SHOW edb_audit_statement; 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_statement = '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.
