Check: PPS9-00-001100
EDB Postgres Advanced Server v9.6 STIG:
PPS9-00-001100
(in versions v2 r3 through v1 r2)
Title
The EDB Postgres Advanced Server must allow only the ISSM (or individuals or roles appointed by the ISSM) to select which auditable events are to be audited. (Cat II impact)
Discussion
Without the capability to restrict which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent or interfere with the auditing of critical events. Suppression of auditing could permit an adversary to evade detection. Misconfigured audits can degrade the system's performance by overwhelming the audit log. Misconfigured audits may also make it more difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.
Check Content
Run the command "ls -al <postgresql data directory>/postgresql*.conf" to show file permissions. (The default path for the postgresql data directory is /var/lib/ppas/9.5/data, but this will vary according to local circumstances.) If the files are not owned by enterprisedb(user)/enterprisedb(group) or does not have RW permission for the user only, this is a finding.
Fix Text
Run these commands: 1) "chown enterprisedb <postgresql data directory>/postgresql*.conf" 2) "chgrp enterprisedb <postgresql data directory>/postgresql*.conf" 3) "chmod 600 <postgresql data directory>/postgresql*.conf" (The default path for the postgresql data directory is /var/lib/ppas/9.5/data, but this will vary according to local circumstances.)
