# Google Cloud Service Account accessing anomalous number of Google Cloud APIs

## Goal{% #goal %}

Detect when a Google Cloud service account is compromised.

## Strategy{% #strategy %}

Inspect the Google Cloud admin activity logs (`@data.logName:*%2Factivity`) and filter for only Google Cloud service accounts (`@usr.id:*.iam.gserviceaccount.com`). Count the unique number of Google Cloud API calls (`@evt.name`) which are being made for each service account (`@usr.id`). The anomaly detection baselines each service account and then generates a security signal when a service account deviates from their baseline.
