Detects when the Google Marketplace restrictions are changed to allow any application for users in Google Workspace. Malicious APKs created by adversaries may be uploaded to the Google marketplace but not installed on devices managed within Google Workspace. Administrators should set restrictions to not allow any application from the marketplace for security reasons. Adversaries may enable any app to be installed and executed on mobile devices within a Google Workspace environment prior to distributing the malicious APK to the end user.

### 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
