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.

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_logwhere event_source = 'ec2.amazonaws.com' and event_name = 'ReplaceRouteTableAssociation' and error_code is null
order by event_time desc;
