What

Per-role preset CSVs - the kit's recommended starting point per host role, each hold-back justified by the settings table's own Risk metadata (no invented pilot numbers):

Preset Selection ATT&CK coverage
role_Workstation.csv Core + process creation/cmdline + script block + WFP connections; DC items deselected 317/362
role_MemberServer.csv as Workstation without WFP connections 299/362
role_DomainController.csv as MemberServer + DC-scope subcategories 302/362

Module logging and Sensitive Privilege Use remain opt-in everywhere (extreme volume / backup-agent flood, per Risk notes). Full per-decision rationale table in docs/baselines.md. Usable with every -BaselineFile (Enable, Test, Intune pack, WEF, GPO pack, coverage, -Show).

Generator gains a role mode (base = Core recommendation, per-role deltas); the CI drift check now covers all six presets.

Verification

  • Self-checks pass on Windows PowerShell 5.1 (all six presets match the generator)
  • mkdocs build --strict clean; PSScriptAnalyzer clean
  • Coverage numbers measured with Export-AttackCoverage.ps1 against each preset

Summary by CodeRabbit

  • New Features

    • Added role-specific baseline presets for workstations, member servers, and domain controllers.
    • Added role-based generation rules, including appropriate audit and registry settings and domain-controller exclusions.
  • Documentation

    • Expanded README and baseline guidance with preset coverage, rationale, and source references.
    • Added PowerShell execution-policy troubleshooting and remediation guidance.
    • Updated roadmap to reflect completed role-preset availability.
  • Tests

    • Strengthened preset consistency checks to compare complete CSV content across all committed presets.

Role presets as documented starting points, derived from the settings
table's Risk metadata rather than invented volume numbers:

- role_Workstation: Core + process creation/cmdline + script block
  logging + WFP connections (client connection volume is modest);
  DC-only items deselected. ATT&CK coverage 317/362.
- role_MemberServer: as Workstation without WFP connections (documented
  High volume on connection-heavy hosts). 299/362.
- role_DomainController: as MemberServer plus DC-scope subcategories,
  still no WFP (DCs are the worst case). 302/362.

Module logging and Sensitive Privilege Use stay opt-in everywhere per
their Risk notes. Rationale table per decision in docs/baselines.md;
generator extended with a role mode; CI drift check covers all six
presets; CHANGELOG v0.5.0 drafted (includes the execution policy docs
fix already on main); ROADMAP item ticked with the pilot-data caveat.

Walkthrough

The PR adds Workstation, MemberServer, and DomainController baseline generation. It validates complete CSV rows across committed and generated presets. It updates documentation for role coverage, rationale, roadmap status, and PowerShell execution-policy remediation.

Changes

Role-based baseline presets

Layer / File(s) Summary
Role preset generation
tools/New-PresetBaselines.ps1
The generator defines role selection rules, validates audit and registry selectors, creates three role CSVs, applies role-specific additions, and excludes DomainController-scoped items from non-DC roles.
Validation and release documentation
tests/Invoke-KitChecks.ps1, README.md, ROADMAP.md, docs/baselines.md, CHANGELOG.md
Preset checks compare all CSV properties. Documentation describes role coverage, selection rules, rationale sources, release status, and PowerShell execution-policy guidance.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 97b07

Per-role preset generation duplicates role-selection metadata outside the settings source of truth, so future settings changes could cause generated presets to drift from the documented configuration. The PR is mergeable with explicit owner follow-up to centralize this metadata.

Move role-selection metadata into LoggingBaseline.Settings.ps1.

ExtraAudit and ExtraReg duplicate audit GUID prefixes and registry IDs in this script. If the settings table changes, the role generator can silently keep an outdated selector and produce an incorrect preset. Store role membership in LoggingBaseline.Settings.ps1 and derive the role selections from $rows.

As per path instructions, every logging setting must live in LoggingBaseline.Settings.ps1 with a plain-language Purpose and Risk where volume or stability matters; settings must not be hardcoded in other scripts.

Source: Path instructions

- CI preset drift check compares ALL CSV columns, so descriptive fields
  cannot go stale unnoticed
- baselines.md rationale table and CHANGELOG execution-policy entry now
  carry their Microsoft source links
- Role selector duplication addressed with a hard validation guard: any
  ExtraAudit/ExtraReg selector that matches no settings-table item fails
  generation (CI runs it every push), converting the silent-drift risk to
  a hard failure without relocating generator policy into the settings
  table (role membership is selection policy, like the reference presets)
