Detection: VPC Route Table Association Replaced

Overview

Detect when a Virtual Private Cloud (VPC) route table association was replaced. Replacing route table associations can disrupt traffic flow, impact application availability, or expose resources to unintended access. Monitoring these changes ensures network integrity and protects against unauthorized modifications.

Usage

Run the detection in your terminal:

powerpipe detection run aws_cloudtrail_log_detections.detection.vpc_route_table_association_replaced

Snapshot and share results via Turbot Pipes:

SQL

This detection uses a named query:

select
tp_timestamp as timestamp,
string_split(event_source, '.')[1] || ':' || event_name as operation,
request_parameters ->> 'routeTableId' 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 = 'ec2.amazonaws.com'
and event_name = 'ReplaceRouteTableAssociation'
and error_code is null
order by
event_time desc;
