Detection: IAM Group Inline Policy Updated
Overview
Detect when an inline policy was created and attached to an IAM group. Inline policies are embedded directly within groups and are harder to manage and audit compared to managed policies, increasing the risk of misconfigurations and excessive permissions. Identifying these actions helps enforce the principle of least privilege and maintain secure access configurations.

Usage
Run the detection in your terminal:
powerpipe detection run aws_cloudtrail_log_detections.detection.iam_group_inline_policy_updatedSnapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe detection run aws_cloudtrail_log_detections.detection.iam_group_inline_policy_updated --shareSQL
This detection uses a named query:
select tp_timestamp as timestamp,string_split(event_source, '.')[1] || ':' || event_name as operation,request_parameters ->> 'policyName' 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_logwhere event_source = 'iam.amazonaws.com' and event_name = 'PutGroupPolicy' and error_code is null
order by event_time desc;
