Version 3.0.2

Description

During Active Directory Reviews, it is beneficial to review all of the GPOs. On a domain controller, the command Get-GPOReport -All -Domain "domain.com" -Server "ACME-DC1" -ReportType HTML -Path "C:\GPOReport.html" will export all of the GPOs for domain.com. All the individual HTML reports will be combined into a single file; having several HTML files inside a single file causes problems, and cannot be read easily, with a browser. Breakdown GPO separates the individual GPOs into individual HTML files that can be opened in a browser.

A summary of the broken down GPOs will be created.

GPOs will be organized according to their status:

• "Enabled" indicates that both computer and user settings are enabled.
• "Computer" indicates that user settings are disabled and computer settings are enabled.
• "User" indicates that computer settings are disabled and user settings are enabled.
• "Disabled" indicates that computer and user settings are enabled.
• GPOs are "ineffective" if they have a security filter of "None" and are enabled ("enabled", "computer", or "user").

GPOs are prepended with a number to preserve the order they are listed in the original GPOReport. Using this ordering, it should be possible to calculate winning GPOs.

Usage

Breakdown GPO

        Usage: python3 .\breakdown_gpo.py -i <input> -o <output>

        Options:

        --input, -i, --in               Define the GPOReport to be broken down.
        --output, -o, --out             Define the output directory.
        --default_output, -do, --do     Use the current working directory as the output directory.
        --help, -h                      Print this help menu.

Version Notes

3.0.2

Introduce Handles Class

Class to maintain file handles.
Makes the code easier to read (kind of).
Provides a count of each type of GPO detected.
Cause why not?

3.0.1

Introduce Indices Class

The Indices class packages all the attribute lists into a single object. The Indices object tracks the number of attributes for each attribute list in the object using decorators. Because the object tracks the attribute list size, instead of using len() before the object was implemented, performance improved.

3.0.0

Major Refactor

The entire project was rewritten to implement Generators and Comprehensions. The introduction of these elements:

• Simplies the code
• Reduces memory consumption - although this is likely negligible for most GPOReports
• Eliminates threading - In initial tests, this had no major impact to performance.
