SQL

This detection uses a named query:

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 'accesscontextmanager.accesspolicies.accesslevels.delete'
  and severity != 'Error'
-- TODO: Do we need to check operation?
-- and (operation_src is null or operation_src.last = true)

order by
  timestamp desc;
