# Spike in GCP Audit Failed Messages
A machine learning job detected a significant spike in the rate of a particular failure in the GCP Audit messages. Spikes
in failed messages may accompany attempts at privilege escalation, lateral movement, or discovery.

## Setup

This rule requires the installation of associated Machine Learning jobs, as well as data coming in from GCP Audit.

### Anomaly Detection Setup

Once the rule is enabled, the associated Machine Learning job will start automatically. You can view the Machine Learning job linked under the "Definition" panel of the detection rule. If the job does not start due to an error, the issue must be resolved for the job to commence successfully. For more details on setting up anomaly detection jobs, refer to the [helper guide](https://www.elastic.co/guide/en/kibana/current/xpack-ml-anomalies.html).

### GCP Audit logs Integration Setup

The Google Cloud Platform (GCP) Audit logs integration allows you to collect logs and metrics from Google Cloud Platform (GCP) with Elastic Agent.

#### The following steps should be executed in order to add the Elastic Agent System "Google Cloud Platform (GCP) Audit logs" integration to your system:

- Go to the Kibana home page and click “Add integrations”.
- In the query bar, search for “Google Cloud Platform (GCP) Audit logs” and select the integration to see more details about it.
- Click “Add Google Cloud Platform (GCP) Audit logs".
- Configure the integration.
- Click “Save and Continue”.
- For more details on the integration refer to the [helper guide](https://www.elastic.co/docs/current/integrations/gcp).
