The vCenter PostgreSQL service must log all connection attempts.


Overview

Finding ID Version Rule ID IA Controls Severity

Description
For completeness of forensic analysis, it is necessary to track successful and failed attempts to log on to PostgreSQL. Setting "log_connections" to "on" will cause each attempted connection to the server to be logged, as well as successful completion of client authentication.

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
