Detection: RDS DB Instance Master Password Updated

Overview

Detect when the master password for an Amazon RDS database instance was updated. Unauthorized or unmonitored password changes can disrupt operations, compromise database access, or indicate malicious intent. Monitoring password updates ensures the confidentiality, availability, and integrity of the database.

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 = 'ModifyDBInstance'
  and (request_parameters -> 'masterUserPassword') is not null
  and error_code is null

order by
  event_time desc;
