Previous commits marked findings as ✅ that were actually superficial or broken. This commit fixes the real problems honestly. Real fixes: - Argon2id KDF: Fixed via preseed partman/early_command that patches partman-crypto's cryptsetup luksFormat to include --pbkdf argon2id. Previous luks-kdf-configure.sh "auto-conversion" was dead code (cryptsetup luksConvertKey needs stdin passphrase, nothing provides it). Now the hook is an honest verifier, not a fake converter. - src/security-hardening.sh: Removed sshd_config generation entirely (was still generating it despite claiming client-only) - AIDE init: Removed || true error swallowing, now reports failures - COMPLIANCE.md: Marked CMMC L3 and FedRAMP as aspirational targets with honest explanation of what's missing (3PAO, org controls) - VERIFICATION-REPORT.md: Added self-review warning about contradictions, fixed wrong preseed path (config/preseed.cfg → includes.installer/) - Removed phantom knel-compliance-check.sh reference from COMPLIANCE.md - encryption-setup.sh: README now says "Argon2id (via early_command)" instead of bare "Argon2id" which was false - demo.preseed.cfg: Added same Argon2id early_command - Added .dockerignore (was missing) - Fixed .gitignore *key* pattern (too broad, matched keyboard.conf etc) Still remaining (honest assessment): - C-06: Git history scrub (needs git-filter-repo, destructive) - H-09: Build cache integrity (design work needed) - M-11: Docker base digest pinning - Phase 3: Test suite overhaul (85% grep-based, not behavioral) - Phase 4: Documentation cleanup (threat model, etc) - ISO NOT rebuilt since fixes 786 tests pass, 0 shellcheck warnings. 💘 Generated with Crush Assisted-by: GLM-5.1 via Crush <crush@charm.land>

# KNEL-Football Compliance Matrix
|
|
|
|
## Overview
|
|
|
|
This document maps security compliance requirements to implementation components in the KNEL-Football secure Debian 13 ISO build system.
|
|
|
|
> **IMPORTANT**: CMMC Level 3 and FedRAMP are **aspirational targets** for future production release.
|
|
> They require organizational controls (policies, assessments, 3PAO reviews) that do not yet exist.
|
|
> Current implementation covers **technical controls only**. No organizational certification has been obtained.
|
|
> DISA STIG IDs are adapted from RHEL STIGs (no Debian 13 STIG exists) and represent technical best-effort alignment.

## Compliance Frameworks
|
|
|
|
| Framework | Status | Notes |
|
|
|-----------|--------|-------|
|
|
| **CMMC Level 3** | 🎯 Aspirational | Requires 130+ practices, 3PAO assessment |
|
|
| **FedRAMP LI-SaaS** | 🎯 Aspirational | Requires agency sponsorship, ConMon |
|
|
| **DISA STIG** | 🔧 Adapted | RHEL STIG IDs applied to Debian 13 (no Debian STIG exists) |
|
|
| **CIS Benchmarks** | ✅ Technical controls | Center for Internet Security Debian Linux Benchmark |
|
|
| **NIST SP 800-53** | ✅ Partial | ~12 controls mapped (800-53 has 1,000+) |
|
|

|
/usr/local/bin/check-encryption.sh
|
|
|
|
# Check security hardening status
|
|
/usr/local/bin/security-hardening.sh
|
|
|
|
# Convert LUKS KDF to Argon2id (if not already done)
|
|
/usr/local/bin/convert-luks-kdf.sh
|
|
```
|
|
|
