This report should be reviewed weekly.

NOTE: In larger organizations reviewing this entire report weekly may not be possible. At a minimum, all Administrator and Super Administrator users should be reviewed, since they are a higher risk. These can be filtered from the overall user list.

Rationale

The App usage report can allow administrator to discover user that are potentially using application that they do not have access to and/or using in atypical ways.

Impact

No user impact.

Audit

To verify this setting via the Google Workspace Admin Console:

1. Log in to https://admin.google.com as an administrator.
2. Select Reporting.
3. Select Reports.
4. Select User Reports.
5. Select App usage, and a table of results will be displayed with the fields listed in the Recommendation description above.
6. Review the displayed users and values for anomalies.

Remediation

The remediation for any anomalies in the various fields varies widely (different sections of the Google Workspace Admin UI). Please refer to Google's documentation for specifics.

NOTE: Many of these settings will be remedied by implementing other sections of this Benchmark. For example, an Admin showing recent Gmail (IMAP) - last used time and/or Gmail (POP) - last used time can be remedied by implementing the Remediation procedure for the recommendation Ensure POP and IMAP access is disabled for all users.

Default Value

The report will display all users and fields.
