If passwords are used for authentication, the EDB Postgres Advanced Server must transmit only encrypted representations of passwords.

Description
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 Text ( C-62987r938795_chk )
Open the "pg_hba.conf" file in a viewer or editor. The default path for the pg_hba.conf file is /var/lib/edb/as/data (PGDATA), but this will vary according to local circumstances. If any rows have TYPE of "hostssl" but do not include "clientcert=1" in the OPTIONS column at the end of the line, this is a finding.

Fix Text (F-62896r938796_fix)
Open the "pg_hba.conf" file in an editor. The default path for the pg_hba.conf file is /var/lib/edb/as/data (PGDATA), but this will vary according to local circumstances. For any rows that have TYPE of "hostssl", append "clientcert=1" in the OPTIONS column at the end of the line.
