Detection: RDS DB Instance IAM Authentication Disabled

Overview

Detect when an Amazon RDS database instance had IAM database authentication disabled. Disabling IAM authentication increases the risk of credential leakage and unauthorized access by relying on static credentials. Enabling IAM authentication simplifies access management, enhances security, and aligns with best practices.

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 = 'ModifyDBInstance'
  and (response_elements -> 'iAMDatabaseAuthenticationEnabled') = false
  and error_code is null

order by
  event_time desc;
