Access Evaluation log events

See how client applications access user data

Depending on your Google Workspace edition, you might have access to the security investigation tool, which has more advanced features. For example, super admins can identify, triage, and take action on security and privacy issues. Learn more

As your organization's administrator, you can use Access Evaluation log events to understand how the different security policies in Google Workspace impact end-users’ access to apps.  For example, an organization can have multiple OAuth policies that control app access based on different rules. Access Evaluation log events show the policies that impact user access, whether access was granted, and how those decisions were made. You can use this information to review and revise your organization's security policies and configuration.

Your ability to run a search depends on your Google edition, your administrative privileges, and the data source. You can run a search on all users, regardless of their Google Workspace edition.

Attribute descriptions

Your organization can have multiple security policies from different sources that impact user access. Access Evaluation logs help you understand the combined behavior of those policies, and which specific policies you might want to change.
 

For example, if unauthorized users are accessing a messaging app, Access Evaluation log events help you understand which policies are being used. If you change a policy, the log events will show the result of that change. 

Access Evaluation log events are also used to investigate your organization’s security posture. For example: 

  • Monitor for suspicious activity: You can use the logs to monitor for suspicious activity, such as attempts to access sensitive data, or access from prohibited locations.
  • Audit your organization's security posture: You can use the logs to audit your organization's security posture and ensure that your data is protected.

A log entry is created for the first event within an 24 hour span. Duplicate events with the same information are not logged until 24 hours has passed. For example, if an entry with User1, Client1 and IP1 occurs at time X, duplicate events with the same information are not logged until 24 hours have passed.

Note: Each log entry may include some, but not all, of the following information. For example, the service account field is typically empty unless access is performed by a service account.
