## Goal{% #goal %}

Detect when Tor client activity is seen in Google Cloud Audit Logs.

## Strategy{% #strategy %}

This rule monitors Google Cloud Audit Logs to determine when an activity had originated from a Tor client. Datadog enriches all ingested logs with [expert-curated threat intelligence](https://docs.datadoghq.com/security/cloud_siem/ingest_and_enrich/threat_intelligence/) in real time. An attacker may use a Tor client to anonymize their true origin.

## Triage and response{% #triage-and-response %}

1. Investigate other activities performed by the identity `{{@usr.id}}` using the Cloud SIEM - User Investigation dashboard.
1. If the results of the triage indicate that an attacker had taken the action, begin your company's incident response process and an investigation.
