.SYNOPSIS
|
|
Parse Microsoft Security Baseline GPO files to JSON (DEVELOPER TOOL ONLY)
|
|
|
|
.DESCRIPTION
|
|
**NOTE: This is a DEVELOPER/MAINTENANCE tool - NOT needed for production use!**
|
|
|
|
The parsed JSON files are already included in Modules/SecurityBaseline/ParsedSettings/.
|
|
This tool is only used during development to update those JSON files when Microsoft
|
|
releases new Security Baselines.
|
|
|
|
Parses GPO backups from Microsoft Security Baseline:
|
|
- Registry.pol (Computer + User)
|
|
- GptTmpl.inf (Security Template)
|
|
- audit.csv (Audit Policies)
|
|
|
|
Outputs structured JSON files for each category.
|
|
|
|
.PARAMETER BaselinePath
|
|
Path to Microsoft Security Baseline folder (download separately from Microsoft)
|
|
Download: https://www.microsoft.com/en-us/download/details.aspx?id=55319
|
|
|
|
.PARAMETER OutputPath
|
|
Path where JSON output files will be saved
