info:
|
|
name: Log Hostname Flag Disabled for PostgreSQL Database Instances
|
|
author: princechaddha
|
|
severity: medium
|
|
description: |
|
|
Ensure that the "log_hostname" database flag is enabled for your Google Cloud PostgreSQL database instances in order to assist with incident response and tracking usage in an environment utilizing dynamic IP addresses. There is a potential cost to server performance caused by hostname logging.
|
|
impact: |
|
|
If the "log_hostname" flag is disabled, tracking and responding to incidents in dynamic IP address environments becomes more challenging, reducing the visibility of database activity and increasing the risk of undetected malicious activity.
|
|
remediation: |
|
|
Enable the "log_hostname" database flag for all PostgreSQL database instances in your Google Cloud environment to ensure proper logging and traceability.
