SV-83625r1_rule The EDB Postgres Advanced Server must maintain the confidentiality and integrity of information during reception.

Vulnerability discussion

Information can be either unintentionally or maliciously disclosed or modified during reception, including, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information.This requirement applies only to those applications that are either distributed or can allow access to data nonlocally. Use of this requirement will be limited to situations where the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process. When receiving data, the DBMS, associated applications, and infrastructure must leverage protection mechanisms.

Check content

If the data owner does not have a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process, this is not a finding. Open "/pg_hba.conf" in a viewer or editor. (The default path for the postgresql data directory is /var/lib/ppas/9.5/data, but this will vary according to local circumstances.) If any rows do not have TYPE of "hostssl" as well as a METHOD of "cert", this is a finding.

Fix text

Open "/pg_hba.conf" in an editor. (The default path for the postgresql data directory is /var/lib/ppas/9.5/data, but this will vary according to local circumstances.) Set all rows to have TYPE of "hostssl" and METHOD of "cert".

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.
