Detection: Logging Sink Deleted
Overview
Detect when a logging sink was deleted in GCP. Logging sinks are essential for exporting logs to external destinations, and their deletion can disrupt log analysis, monitoring, and compliance processes. Monitoring these events ensures the continuity of logging workflows and prevents unauthorized or accidental removal of sinks.

Usage
Run the detection in your terminal:
powerpipe detection run gcp_audit_log_detections.detection.logging_sink_deletedSnapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe detection run gcp_audit_log_detections.detection.logging_sink_deleted --shareSQL
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_logwhere method_name ilike 'google.logging.v%.configservicev%.deletesink' and severity != 'Error'-- TODO: Do we need to check operation?-- and (operation_src is null or operation_src.last = true)
order by timestamp desc;
