Overview of Sensitive Actions Service

This page provides an overview of Sensitive Actions Service, a built-in service of Security Command Center that detects when actions are taken in your Google Cloud organization, folders, and projects that could be damaging to your business if they are taken by a malicious actor.

In most cases, the actions that are detected by Sensitive Actions Service do not represent threats, because they are taken by legitimate users for legitimate purposes. However, the Sensitive Actions Service cannot conclusively determine legitimacy, so you might need to investigate the findings before you can be sure that they don't represent a threat.

How Sensitive Actions Service works

Sensitive Actions Service automatically monitors all of your organization's Admin Activity audit logs for sensitive actions. Admin Activity audit logs are always on, so you do not need to enable or otherwise configure them.

When Sensitive Actions Service detects a sensitive action that is taken by a Google account, Sensitive Actions Service writes a finding to Security Command Center in the Google Cloud console and a log entry to the Google Cloud platform logs.

Sensitive Actions Service findings are classified as observations and can be viewed by finding class or finding source on the Findings tab in the Security Command Center dashboard.


The following sections describe restrictions that apply to Sensitive Actions Service.

Account support

Sensitive Actions Service detection is limited to actions taken by user accounts.

Encryption and data residency restrictions

To detect sensitive actions, Sensitive Actions Service must be able to analyze your organization's Admin Activity audit logs.

If your organization encrypts your logs by using customer-managed encryption keys (CMEK) to encrypt your logs, Sensitive Actions Service cannot read your logs and, consequently, cannot alert you when sensitive actions occur.

Sensitive actions cannot be detected if you have configured the location of the log bucket for your your Admin Activity Audit Logs to be in a location other than the global location. For example, if you have specified a storage location for the _Required logs bucket in a certain project, folder, or organization, logs from that project, folder, or organization cannot be scanned for sensitive actions.

Sensitive Actions Service findings

The following table shows the finding categories that Sensitive Actions Service can produce. The display name for each finding starts with the MITRE ATT&CK tactic that the detected action could be used for.
