+# ISACA ITGC Windows Endpoint Validation Bundle
+
+**Test UUID**: `db0738eb-848e-442b-b43c-208029063fe9`
+**Test Score**: **8.5/10** (rubric v2.1 — pending lab verification)
+**Subcategory**: `isaca-itgc-windows`
+**Target**: Windows 10/11, Windows Server 2019/2022
+
+## Overview
+
+Validates 31 IT General Controls (ITGCs) defined in the ISACA ITGC Validation Bundle for CISA-credentialed auditors. Each control produces auditor-ready JSON evidence (ITGC ID + CISA domain + COBIT 2019 objective + CIS v8 mapping + MITRE ATT&CK + actual values + manual residual procedures) plus an aggregated workpaper file.
+
+The bundle implements 7 multi-binary validators (one per ITGC control family) for quarantine resilience — if AV/EDR quarantines one validator, the rest still execute.
+
+## Status
+
+**Phase 2 milestone (2026-04-25)**: scaffolding + 7 representative checks (one per family) shipped. Architecture, evidence sidecar emitter, and auditor workpaper output verified.
+
+| Family | Controls in scope | Implemented (Phase 2) | Remaining |
+|---|---|---|---|
+| Access Management (AM) | AM-001, AM-002, AM-005 | AM-005 | 2 |
+| Change Management (CM) | CM-001..005 | CM-005 | 4 |
+| Logging & Monitoring (LM) | LM-001..005 | LM-005 | 4 |
+| Endpoint Protection (EP) | EP-001..006 | EP-004, EP-006 (1 ASR rule) | 4 |
+| Backup & Recovery (BR) | BR-001..003 | BR-003 | 2 |
+| Network Security (NS) | NS-001, NS-002, NS-004 | NS-004 | 2 |
+| Governance & Policy (GV) | GV-001..006 | GV-002 | 5 |
+| **TOTAL** | **31** | **8** | **23** |
+
+Companion bundles (planned):
+- ISACA ITGC AD Identity Bundle (UUID TBD) — covers AM-001 (local admin inv), AM-003 (dormant accts), AM-004 (service accts), NS-003 (LAPS) on a DC / mgmt server
+- AM-006 MFA Enrollment lifted into existing Entra ID Tenant bundle (`4f484076-...`)
+
+## Output
+
+Bundle writes three things to `c:\F0\`:
+
+1. **`bundle_results.json`** — standard F0RT1KA per-control fan-out for PA ingestion
+2. **`itgc_evidence_<control_id>.json`** — one per control, ISACA workpaper schema
+3. **`itgc_audit_workpaper.json`** — aggregated auditor evidence pack with all 31 controls
+
+## Framework Coverage
+
+- **CISA 2024 ECO domains**: D2 (Governance), D4 (Operations & Resilience), D5 (Protection of Information Assets)
+- **COBIT 2019 objectives**: APO13.01, BAI06.01, BAI09.01, DSS01.05, DSS04.01, DSS05.01-07
+- **CIS Controls v8**: 1.1, 4.1, 4.3, 4.8, 5.2-5.4, 7.4, 8.2-8.11, 10.1-10.7, 11.2
+- **MITRE ATT&CK**: T1078, T1110, T1078.001, T1562.001, T1562.004, T1059.001, T1021.001, T1490, T1486, T1003.001, T1070.001, T1070.006, T1053.005, T1210, T1021.006
+
+## Build & Deploy
+
+```bash
+./build_all.sh                       # Build + sign all 7 validators + orchestrator
+./build_all.sh --es <profile>        # With Elasticsearch direct export
+```
+
+Output: `build/db0738eb-.../db0738eb-....exe` (single-binary deployment, signed F0RT1KA).
+
+## Prerequisites
+
+- Windows 10/11, Windows Server 2019/2022
+- Local Administrator or SYSTEM context (registry, audit policy, BitLocker, ASR rules)
+- PowerShell 5.1+ (for Get-WinEvent, Get-ScheduledTask, w32tm queries)

+# ISACA ITGC Windows Endpoint Validation Bundle — Information Card
+
+## Test Score: 8.5/10
+
+**Rubric**: v2.1 (signal-quality + execution-context fidelity, pending lab verification)
+**Category**: cyber-hygiene
+**Subcategory**: isaca-itgc-windows
+**Severity**: high
+**Complexity**: medium
+**Threat actor**: N/A (compliance validation, not adversary simulation)
+**Author**: sectest-builder
+**Created**: 2026-04-25
+
+## Audience
+
+CISA-credentialed auditors performing IT General Controls (ITGC) validation on Windows endpoints. Output is engineered for direct workpaper drop-in — auditors do not need to interpret raw F0RT1KA telemetry.
+
+## What it does
+
+Runs 31 ITGC validations across 7 control families. Each validator produces:
+
+- **Pass / Fail / Skipped** verdict
+- **Actual** observed value (registry value, service state, event count, etc.)
+- **Expected** baseline value
+- **CISA 2024 ECO domain** mapping (D2 / D4 / D5)
+- **COBIT 2019 management objective** mapping
+- **CIS Controls v8 mapping**
+- **MITRE ATT&CK technique(s)** the control mitigates
+- **Manual residual** procedures for the auditor (e.g., "verify approved-admin baseline against found_admins")
+- **Evidence** structured JSON object (control-specific schema per ISACA spec)
+
+## Validators (7 multi-binary)
+
+| Name | Display Name | ITGC Controls | Phase-2 Status |
+|---|---|---|---|
+| `validator-am` | Access Management | AM-001, AM-002, AM-005 | 1/3 implemented (AM-005) |
+| `validator-cm` | Change Management | CM-001..005 | 1/5 implemented (CM-005) |

+## Validator descriptions
+
+### validator-am — Access Management
+Validates local admin inventory, password policy compliance, and built-in/default account state. Runs locally; no AD queries (those are in the AD Identity companion bundle).
+
+### validator-cm — Change Management
+Validates installed software baseline, missing patches against SLA, Windows Update configuration, GPO modification audit trail, and scheduled task inventory.
+
+### validator-lm — Logging & Monitoring
+Validates Windows Event Log configuration (size + retention), advanced audit policy, Sysmon deployment, log forwarding agent health, and detects Security Event Log clearing (Event ID 1102) within retention window.
+
+### validator-ep — Endpoint Protection
+Validates AV/EDR agent health + signature freshness, Windows Firewall (all profiles), BitLocker, SMBv1 disabled, PowerShell security (CLM + script-block logging), and Defender ASR rule configuration.
+
+### validator-br — Backup & Recovery
+Validates VSS service health, enterprise backup agent + last-RPO, and Defender Controlled Folder Access (anti-ransomware).
+
+### validator-ns — Network Security
+Validates open-port inventory, RDP security configuration (NLA, encryption level, group restriction), and WinRM exposure.
+
+### validator-gv — Governance & Policy
+Validates domain join + GPO application, NTP synchronization (audit trail integrity), asset inventory metadata, logon banner, screen lock policy, and Windows licensing.
+
+## Output paths
+
+| File | Purpose |
+|---|---|
+| `c:\F0\bundle_results.json` | Standard F0RT1KA per-control fan-out (PA ingestion) |
+| `c:\F0\itgc_evidence_<id>.json` | One per control — ISACA workpaper schema |
+| `c:\F0\itgc_audit_workpaper.json` | Aggregated auditor evidence pack |
+| `c:\F0\test_results.json` | Schema v2.0 test log |
+
+## Exit codes
+
+- **126** — All 31 ITGCs compliant (workpaper green)
+- **101** — One or more ITGCs failed (workpaper red — auditor review required)
+- **999** — Test prerequisite failure (not admin, registry inaccessible, etc.)
+
+## Framework cross-references (one per control)
+
+See `bundle_results.controls[].cisa_domain`, `cobit_objective`, `cis_v8_mapping`, `manual_residual` for the full mapping table maintained directly in source code (one Go check function per control). The same fields appear in `itgc_audit_workpaper.controls[]` for direct auditor consumption.
