Detection: CodeBuild Project Service Role Updated

Overview

Detect when an service role associated with an AWS CodeBuild project was updated. Unauthorized or unintended role changes can grant excessive permissions, disrupt build processes, or expose sensitive resources. Monitoring service role updates ensures permissions align with the principle of least privilege and safeguards the security of build environments.

SQL

This detection uses a named query:

select
  tp_timestamp as timestamp,
string_split(event_source, '.')[1] || ':' || event_name as operation,
request_parameters ->> 'name' 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 = 'codebuild.amazonaws.com'
  and event_name = 'UpdateProject'
  and (request_parameters ->> 'serviceRole') is not null
  and error_code is null

order by
  event_time desc;
