Detection: RDS DB Instance Restored from Public Snapshot

Overview

Detect when an Amazon RDS database was restored with public accessibility enabled. Restoring databases with public access exposes them to the internet, increasing the risk of unauthorized access, data breaches, and exploitation. Ensuring databases are restored with public access disabled protects data confidentiality and reduces the attack surface.

Usage

Run the detection in your terminal:

powerpipe detection run aws_cloudtrail_log_detections.detection.rds_db_instance_restored_from_public_snapshot

SQL

This detection uses a named query:

select
  tp_timestamp as timestamp,
string_split(event_source, '.')[1] || ':' || event_name as operation,
request_parameters ->> 'dBInstanceIdentifier' as resource,
user_identity.arn as actor,
tp_source_ip as source_ip,
tp_index as account_id,
aws_region as region,
tp_id as source_id,
*

from
  aws_cloudtrail_log
where
  event_source = 'rds.amazonaws.com'
  and event_name = 'RestoreDBInstanceFromDBSnapshot'
  and (request_parameters -> 'publiclyAccessible') = true
  and error_code is null

order by
  event_time desc;
