Google Workspace Admin Role Assigned to a User

edit

Assigning the administrative role to a user will grant them access to the Google Admin console and grant them administrator privileges which allow them to access and manage various resources and applications. An adversary may create a new administrator account for persistence or apply the admin role to an existing user to carry out further intrusion efforts. Users with super-admin privileges can bypass single-sign on if enabled in Google Workspace.

Investigation guide

### Important Information Regarding Google Workspace Event Lag Times
- As per Google's documentation, Google Workspace administrators may observe lag times ranging from minutes up to 3 days between the time of an event's occurrence and the event being visible in the Google Workspace admin/audit logs.
- This rule is configured to run every 10 minutes with a lookback time of 130 minutes.
- To reduce the risk of false negatives, consider reducing the interval that the Google Workspace (formerly G Suite) Filebeat module polls Google's reporting API for new events.
- By default, `var.interval` is set to 2 hours (2h). Consider changing this interval to a lower value, such as 10 minutes (10m).
