Vulnerability discussion

The DoD standard for authentication is DoD-approved PKI certificates.Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate, and requires AO approval.In such cases, passwords need to be protected at all times, and encryption is the standard method for protecting passwords during transmission.DBMS passwords sent in clear text format across the network are vulnerable to discovery by unauthorized users. Disclosure of passwords may easily lead to unauthorized access to the database.

Check content

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 have "password" specified for the "METHOD" column, 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.) For any rows that have "password" specified for the "METHOD" column, change the value to "md5".

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.
