I think this entry can be seen as a Troubleshooting script and as a Reporting/Auditing script.
The script uses the draft Security Hardening Guide for Guests as a guideline.
You can run the script as a reporting tool where you get a list of the current compliance with the guidelines from the hardening guide.
And you can run the script as a corrective tool to update the settings to comply with the guidelines of the hardening guide.
See Security – Hardening – Part 1 – Virtual Machines for the script, the description and a sample run.
