Description
Failure to a known secure state helps prevent a loss of confidentiality, integrity, or availability in the event of a failure of the information system or a component of the system. Preserving system state information helps to facilitate system restart and return to the operational mode of the organization with less disruption of mission/business processes. Aggregating log writes saves on performance but leaves a window for log data loss. The logging system inside PostgreSQL is capable of writing logs to disk, fully and completely before the associated operation is returned to the client. This ensures that database activity is always captured, even in the event of a system crash during or immediately after a given operation.

ℹ️ Check
At the command prompt, run the following command: # /opt/vmware/vpostgres/current/bin/psql -U postgres -A -t -c "SELECT name,setting FROM pg_settings WHERE name IN ('fsync','full_page_writes','synchronous_commit');" Expected result: fsync \| on full_page_writes \| on synchronous_commit \| on If the output does not match the expected result, this is a finding.

✔️ Fix
A script is included with vCenter to generate a PostgreSQL STIG configuration. At the command prompt, run the following commands: # chmod +x /opt/vmware/vpostgres/current/bin/vmw_vpg_config/vmw_vpg_config.py # /opt/vmware/vpostgres/current/bin/vmw_vpg_config/vmw_vpg_config.py --action stig_enable --pg-data-dir /storage/db/vpostgres # chmod -x /opt/vmware/vpostgres/current/bin/vmw_vpg_config/vmw_vpg_config.py Restart the PostgreSQL service by running the following command: # vmon-cli --restart vmware-vpostgres
