Introducing Sensitive Actions To Help Keep Accounts Secure

At Google Cloud, we operate in a shared fate model, working in concert with our customers to help achieve stronger security outcomes. One of the ways we do this is to identify potentially risky behavior to help customers determine if action is appropriate. To this end, we now provide insights on what we are calling Sensitive Actions.Sensitive Actions, now available in Preview, are focused on understanding IAM account, or user account, behavior. They are changes made in a Google Cloud environment that are security relevant — and therefore important to be aware of and evaluate — because they may be precursors to an attack, an effort to make other attacks possible, or part of an effort to monetize a compromised account. They can quickly highlight potentially malicious activities that are facilitated by authentication cookie theft, and are another defense-in-depth mechanism that Google Cloud offers to help address this attack vector.The Sensitive Actions that are detected today will appear in two places. They are available in Security Command Center Premium, the primary source for security and risk alerts in Google Cloud, as Observations from the Sensitive Actions Service. They are also available in Cloud Logging, where we recommend that customers integrate them into their monitoring workflows.Sensitive Actions include the following list of action names (mapped to the MITRE ATT&CK tactics that these actions may correspond to) and descriptions:

To ensure that adversaries do not have mechanisms to disable this protection or hide logs from users, Sensitive Actions is an on-by-default service now enabled for Cloud customers. In cases where customers have certain privacy controls or policy restrictions applied to their logging pipeline, their logs will not be analyzed by this service.You can learn more about Sensitive Actions and our overall recommendations for keeping your account secure by visiting ourdocumentation here.
