|

Read-only WAPT audit of Windows security configurations using the upstream
|
||||
[HardeningKitty / windows_hardening](https://github.com/0x6d69636b/windows_hardening)
|
||||
module. This is a **WAPT package SOURCE**, not a signed and deployable `.wapt` file.
|
||||
|
||||
## How it works
|
||||
|
||||
1. On the WAPT packaging workstation, `update_package()` (or
|
||||
`python tools/vendor_assets.py`) downloads **pinned commit**
|
||||
`acf9ecee3d044a9337df7aad80e730cbd746e8de` from GitHub over HTTPS.
|
||||
It creates `vendor/` containing the official PowerShell module, the MIT
|
||||
license, all finding lists, the upstream signed finding-list manifest and a
|
||||
reproducible local SHA-256 manifest. It does not download a floating `master`.
|
||||
2. You review the upstream files, **build and sign** the WAPT package as usual.
|
||||
The signed package is deployed from your WAPT repository. Windows clients do
|
||||
not access GitHub and do not require PowerShell Gallery.
|
||||
3. `install()` checks SHA-256 of all vendored files, copies them to a locked
|
||||
directory under `%ProgramData%\Comitari\Audit-HardeningKitty` and creates a
|
||||
separate private reports directory.
|
||||
4. The package `audit()` launches 64-bit Windows PowerShell 5.1 under the WAPT
|
||||
service account. It calls `Invoke-HardeningKitty` with **`-Mode Audit` only**,
|
||||
then evaluates the official CSV report. There is no remediation code.
|
||||
5. `audit()` compares the report to the source finding list. Missing/skipped
|
||||
checks are recorded as unknown and make the status `ERROR` (never false OK).
|
||||
The full report and PowerShell log stay on the audited workstation.
|
||||
6. WAPT gets an `OK`, `WARNING`, or `ERROR` status. WAPT Enterprise also gets
|
||||
metrics and findings through `write_audit_data_if_changed()` in section
|
||||
`HardeningKitty`; when that function is unavailable, the audit status and
|
||||
local reports still work.
|
||||
|
||||
## Prepare, build, sign, deploy
|
||||
|
||||
Extract this source archive into your WAPT development directory as
|
||||
`comi-audit-hardeningkitty`. On a packaging workstation with Python 3 and
|
||||
Internet access:
|
||||
|
||||
```powershell
|
||||
cd C:\waptdev\comi-audit-hardeningkitty
|
||||
py -3 tools\vendor_assets.py --dest vendor
|
||||
py -3 -m unittest discover -s tests -v
|
||||
```
|
||||
|
||||
Alternatively, use **update-package** in the WAPT IDE; `setup.py` exposes
|
||||
`update_package()` for the same operation. The vendor script can also accept
|
||||
`--archive C:\path\to\github-commit.zip --archive-sha256 <SHA256>` to prepare
|
||||
from an explicitly checked local archive.
|
||||
|
||||
Review `vendor/`, then build, sign and upload the package from the WAPT Console
|
||||
using your standard certificate. **Do not sign/build before populating
|
||||
`vendor/`**. You cannot deploy this source ZIP directly as a WAPT package.
|
||||
|
||||
Assign the package to Windows machines. `audit_schedule: 1w` in `WAPT/control`
|
||||
requests weekly checks after installation; edit to `1d` for daily checks if
|
||||
appropriate for your fleet. Force an audit on a test host with:
|
||||
|
||||
```cmd
|
||||
wapt-get audit -f
|
||||
```
|
||||
|
||||
## Baseline selection
|
||||
|
||||
`audit_config.json` defaults to `"profile": "auto"` and `"source": "GPO"`.
|
||||
The PowerShell wrapper detects Windows using CIM and reads `DisplayVersion` /
|
||||
Windows build. It deliberately refuses unsupported systems, rather than silently
|
||||
selecting an incorrect benchmark:
|
||||
|
||||
| Target | Benchmark selection |
|
||||
| --- | --- |
|
||||
| Windows 11 21H2 to 26H2 | Matching Microsoft Security Baseline (machine) |
|
||||
| Windows 10 20H2, 21H1, 21H2, 22H2 | Matching Microsoft Security Baseline (machine) |
|
||||
| Windows Server 2012 R2, 2016, 2019 | Latest available CIS benchmark in pinned snapshot (machine) |
|
||||
| Windows Server 2022 | Microsoft Security Baseline 2022, DC/member |
|
||||
| Windows Server 2025 | Microsoft Security Baseline 2025, DC/member |
|
||||
|
||||
For a vendor-agnostic research baseline, set `"profile": "community"` to use
|
||||
`finding_list_0x6d69636b_machine.csv`. You may also specify the exact name of
|
||||
any bundled `finding_list_*_machine.csv`, e.g.
|
||||
`"finding_list_cis_microsoft_windows_11_enterprise_25h2_machine.csv"`.
|
||||
Windows user profiles are **not** audited: WAPT normally runs as LocalSystem,
|
||||
and checking `*_user.csv` would give misleading results for the logged-in user.
|
||||
The wrapper rejects them. An Intune policy source can be selected with
|
||||
`"source": "Intune"`, but it still uses an OS-compatible finding list; test
|
||||
this mode before rollout, since not all controls expose an Intune mapping.
|
||||
|
||||
## Severity mapping
|
||||
|
||||
| Situation | WAPT audit status |
|
||||
| --- | --- |
|
||||
| No failed/skipped checks | `OK` |
|
||||
| Low/Medium baseline deviation | `WARNING` |
|
||||
| High baseline deviation | `ERROR` |
|
||||
| Missing/skipped checks, empty/malformed report, missing upstream asset, unsupported OS, timeout | `ERROR` |
|
||||
|
||||
The severity is **upstream policy severity**, not a CVSS score. You can change
|
||||
`error_on_high` to `false` to map High deviations to `WARNING`, or `warn_on_low`
|
||||
to `false` to ignore low-severity deviations for the aggregate status. Missing
|
||||
or indeterminate checks always produce `ERROR`.
|
||||
|
||||
## Audit data and locations
|
||||
|
||||
WAPT Enterprise section: `HardeningKitty`. Keys include `status`, `benchmark`,
|
||||
`os_build`, `source`, `upstream_commit`, `passed`, `high`, `medium`, `low`,
|
||||
`unknown`, `executed`, `expected`, `skipped`, `total`, `compliant_percent`,
|
||||
`last_run_utc`, `last_error` and 16 stable JSON shards (`findings_00` ... `findings_15`).
|
||||
All 16 shards are written, even when empty, avoiding stale findings from prior
|
||||
runs. Shard entries contain ID, name, category, severity and test result.
|
||||
`publish_current_values` defaults to `false` to avoid exposing local security
|
||||
configuration details in WAPT audit-data. Enable only if policy allows it.
|
||||
|
||||
Local reports (restricted to SYSTEM/Administrators):
|
||||
|
||||
```text
|
||||
C:\ProgramData\Comitari\Audit-HardeningKitty-Reports\run-YYYYMMDD-HHMMSS-XXXXXXXX\
|
||||
hardeningkitty.csv
|
||||
powershell.log
|
||||
host.json
|
||||
summary.json
|
||||
```
|
||||
|
||||
`retain_audit_runs` defaults to 8. `uninstall()` removes the engine but retains
|
||||
historical reports for traceability. WAPT Enterprise may show the last values
|
||||
for each changed metric with a 120-day retention (`max_count` varies by metric).
|
||||
The raw CSV can contain sensitive host configuration and never leaves the
|
||||
machine unless explicitly exported by the administrator.
|
||||
|
||||
## Operational considerations
|
||||
|
||||
- **No Windows hardening is applied.** The package never executes HailMary,
|
||||
GPO, registry changes or remediation. The upstream Audit mode may create and
|
||||
delete transient files needed to inspect local policy.
|
||||
- Test on one Windows 10 and Windows 11 workstation (and representative server
|
||||
versions) before fleet deployment. The upstream README warns that some checks
|
||||
may be inaccurate on non-English systems.
|
||||
- Test memory, CPU and duration against your fleet. Default timeout is 900
|
||||
seconds; increase `timeout_seconds` for slow hosts if necessary.
|
||||
- Windows PowerShell 5.1 and sufficient machine-level privileges are required.
|
||||
The wrapper requests process-local execution-policy Bypass; WDAC/CLM/AppLocker
|
||||
may still block unsigned PowerShell modules. Adapt the signing strategy to
|
||||
your enterprise policy rather than disabling those protections.
|
||||
- Pinning and file hashing ensure reproducibility and post-packaging integrity,
|
||||
but you must still review external executable PowerShell code before trusting
|
||||
it. The MIT upstream LICENSE is included with the actual WAPT payload.
|
||||
- Mismatches to a benchmark do **not** automatically imply a vulnerability or
|
||||
justify remediation: validate the expected value against business use and
|
||||
any domain/Intune GPO before taking action.
|
||||
|
||||
## Validation status
|
||||
|
||||
The Python parser, status mapping, coverage detection, privacy defaults,
|
||||
local manifest verification and offline archive extraction have unit tests
|
||||
under `tests/`. A real PowerShell audit on a Windows machine and an end-to-end
|
||||
WAPT signed install must still be validated in your environment.
