Investigation guide
edit## Config The Google Workspace Fleet integration, Filebeat module, or similarly structured data is required to be compatible with this rule. ### 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). - See the following references for further information: - https://support.google.com/a/answer/7061566 - https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-module-google_workspace.html
