Fix Recommendation

Disable each prohibited network function, port, protocol, or service prohibited by the PPSM guidance.

Open "<postgresql data directory>/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.) Change the TYPE of any rows not starting with a "#" to be either "local" or "hostssl". The METHOD for the local rows should be "peer", which will authenticate based on the operating system name. The METHOD for the hostssl rows should be one of these (in preferred order): cert, ldap, sspi, pam, md5

Execute the following SQL as enterprisedb:

ALTER SYSTEM SET port = <port>;

Execute the following operating system command as root:

systemctl restart ppas-9.5.service

Check Contents

Review the network functions, ports, protocols, and services supported by the DBMS.

If any protocol is prohibited by the PPSM guidance and is enabled, this is a finding.

Open "<postgresql data directory>/pg_hba.conf" in a viewer. (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 a TYPE that is "host" or "hostnossl", this is a finding.

Execute the following SQL as enterprisedb:

SHOW port;

If the displayed port is not allowed, this is a finding.
