Detection: IAM Service Account Disabled

Overview

Detect when an IAM service account was disabled in GCP. Disabling a service account can prevent applications or services from accessing GCP resources, potentially causing disruptions. Monitoring these events helps ensure operational continuity and prevents accidental or unauthorized changes to critical service accounts.

select
  tp_timestamp as timestamp,
method_name as operation,
resource_name as resource,
authentication_info.principal_email as actor,
tp_source_ip as source_ip,
tp_index as project,
tp_id as source_id,
-- Create new aliases to preserve original row data
*

from
  gcp_audit_log
where
  method_name ilike 'google.iam.admin.v%.disableserviceaccount'
  and severity != 'Error'
-- TODO: Do we need to check operation?
-- and (operation_src is null or operation_src.last = true)

order by
  timestamp desc;
