## Components
|
||||
|
||||
### Host System
|
||||
|
||||
The host system is intentionally restricted to prevent build tool contamination:
|
||||
|
||||
- **Git** - Version control for all source code and configurations
|
||||
- **Docker** - Container runtime for isolated build environment
|
||||
- **Libvirt** - Virtualization for ISO testing (optional)
|
||||
|
||||
### Build Container
|
||||
|
||||
The Docker container provides a clean, reproducible build environment:
|
||||
|
||||
- **Base System** - Debian 13.3-slim minimal base
|
||||
- **Build Tools** - live-build, debootstrap, squashfs-tools
|
||||
- **Security Tools** - nftables, auditd, rsyslog
|
||||
- **Testing Framework** - bats-core with support libraries
|
||||
|
||||
### Build Process
|
||||
|
||||
The ISO build process uses live-build with extensive customization:
|
||||
|
||||
1. **Bootstrap Phase** - Minimal Debian base system creation
|
||||
2. **Configuration Phase** - Package installation and system configuration
|
||||
3. **Hook Execution** - Security hardening and customization
|
||||
4. **Image Creation** - Final ISO generation
|
||||
|
||||
### Output System
|
||||
|
||||
The resulting ISO provides a secure, compliant operating system:
|
||||
|
||||
- **Minimal Desktop** - IceWM with essential applications
|
||||
- **Network Security** - WireGuard-only access with dynamic firewall
|
||||
- **System Hardening** - Comprehensive security configuration
|
||||
- **Compliance** - CMMC Level 3, FedRAMP, STIG, CIS compliant
|
||||
|
||||
## Data Flow
|
||||
|
||||
### Source to Build
|
||||
|
||||
1. **Developer** pushes code changes to Git repository
|
||||
2. **Docker** builds container image with all dependencies
|
||||
3. **Run Script** orchestrates the build process
|
||||
4. **Live-build** creates ISO from configuration
|
||||
5. **Tests** validate the build process and output
|
||||
|
||||
### Build to Deployment
|
||||
|
||||
1. **ISO Generation** - Creates secure, bootable image
|
||||
2. **Testing** - Validates security and functionality
|
||||
3. **Distribution** - Secure delivery to end users
|
||||
4. **Installation** - Manual setup by privileged users
|
||||
5. **Configuration** - VPN setup and customization
|
||||
|
||||
## Security Architecture
|
||||
|
||||
### Isolation
|
||||
|
||||
- **Container Isolation** - Build process isolated from host
|
||||
- **Network Isolation** - No general internet access
|
||||
- **Service Isolation** - Minimal running services
|
||||
- **User Isolation** - Privilege separation
|
||||
|
||||
### Immutable Infrastructure
|
||||
|
||||
- **Source Controlled** - All configuration in version control
|
||||
- **Containerized Builds** - Reproducible build environment
|
||||
- **Immutable OS** - Package management disabled
|
||||
- **Verified Boot** - Secure boot with measured components
|
||||
|
||||
### Defense in Depth
|
||||
|
||||
- **Multiple Security Layers** - Network, system, application, access
|
||||
- **Fail-Safe Defaults** - Secure by default configuration
|
||||
- **Comprehensive Auditing** - Complete system activity logging
|
||||
- **Compliance Validation** - Automated compliance checking
|
||||
|
||||
## Quality Assurance
|
||||
|
||||
### Test-Driven Development
|
||||
|
||||
1. **Test First** - Tests written before implementation
|
||||
2. **100% Coverage** - All code and configurations tested
|
||||
3. **Automated Testing** - Continuous test execution
|
||||
4. **Multiple Test Types** - Unit, integration, security tests
|
||||
|
||||
### Continuous Validation
|
||||
|
||||
1. **Linting** - Code quality and style checking
|
||||
2. **Security Scanning** - Vulnerability assessment
|
||||
3. **Compliance Testing** - Framework validation
|
||||
4. **Performance Testing** - Resource usage validation
|
||||
|
||||
## Deployment Architecture
|
||||
|
||||
### Build Deployment
|
||||
|
||||
1. **Source Repository** - All code and configurations
|
||||
2. **Build Environment** - Containerized build system
|
||||
3. **CI/CD Pipeline** - Automated build and test
|
||||
4. **Artifact Repository** - ISO storage and distribution
|
||||
|
||||
### System Deployment

## Installation Automation
|
||||
|
||||
### Build Process
|
||||
- **Tool**: `live-build` for ISO generation
|
||||
- **Base Image**: Debian 13.3.0 (Trixie) netinst
|
||||
- **Specific ISO**: debian-13.3.0-amd64-netinst.iso from official Debian mirrors
|
||||
- **Customization**: Config hooks for security hardening
|
||||
|
||||
### Preseed Configuration
|
||||
- **File**: `config/preseed.cfg`
|
||||
- **Automated Items**:
|
||||
- Localization settings (US/Chicago timezone, US English keyboard)
|
||||
- Software package selection
|
||||
- Password complexity enforcement
|
||||
- Timezone configuration
|
||||
- Keyboard layout
|
||||
- **Manual Items**:
|
||||
- Disk partitioning
|
||||
- Root password setup
|
||||
- Non-root user creation (auto-added to sudo group)
|
||||
|
||||
## Development Environment & Constraints
|
||||
|
||||
### Host System Restrictions
|
||||
- **Forbidden Tools**:
|
||||
- Make (no build automation)
|
||||
- Python (no scripting language)
|
||||
- Ruby (no scripting language)
|
||||
- Any build tools directly on host
|
||||
- **Allowed Tools**:
|
||||
- `docker` (container runtime)
|
||||
- `git` (version control)
|
||||
- `libvirt` (virtualization tools: virt-install, virsh)
|
||||
|
||||
### Container-Based Workflow
|
||||
- **Single Entry Point**: `run.sh` wrapper script
|
||||
- **Build Environment**: Docker container with all dependencies
|
||||
- **Build Tools Inside Container**:
|
||||
- `live-build`
|
||||
- `debootstrap`
|
||||
- `bats-core`
|
||||
- `shellcheck`
|
||||
- Security hardening tools
|
||||
|
||||
### File Permissions
|
||||
- All generated files owned by invoking user
|
||||
- Docker volume mounts with proper UID/GID mapping
|
||||
- No root-owned output files
|
||||
- Package management tools disabled with `chmod -x` and `chattr +i`
|
||||
- Test suite included in ISO for post-install validation
|
||||
|
||||
## Quality Assurance & Testing
|
||||
|
||||
### Test-Driven Development
|
||||
- **Methodology**: Tests written before implementation
|
||||
- **Test Coverage**: 100% mandatory coverage
|
||||
- **Test Types**:
|
||||
- Unit tests for logic components
|
||||
- Integration tests for ISO generation
|
||||
- Security validation tests
|
||||
|
||||
### Testing Framework
|
||||
- **Primary Tool**: `bats-core` (Bash Automated Testing System)
|
||||
- **Linting**: `shellcheck` for all shell scripts
|
||||
- **Code Standards**: Strict mode with `set -euo pipefail`
|
||||
|
||||
### Test Organization
|
||||
```
|
||||
tests/
|
||||
├── unit/ # Unit tests for individual functions
|
||||
├── integration/ # Integration tests for complete workflows
|
||||
├── security/ # Security validation tests
|
||||
└── fixtures/ # Test data and mocks
|
||||
```
|
||||
|
||||
## Compliance Requirements
|
||||
|
||||
### Standards Framework
|
||||
- **CMMC Level 3** - Entry point to tier0 infrastructure supporting ITAR/SECRET systems
|
||||
- **FedRAMP LI-SaaS** - For RackRental.net federal government product
|
||||
- **STIG** - DISA STIG for Debian (adapt Debian 11 STIG for Debian 13)
|
||||
- **CIS Benchmarks** - CIS Benchmark for Debian Linux (baseline security controls)
|
||||
|
||||
### Compliance Documentation
|
||||
- **Matrix Document**: `COMPLIANCE.md`
|
||||
- **Mapping**: STIG IDs and CIS controls to build hooks
|
||||
- **Validation**: Automated compliance verification tests
|
||||
|
||||
### Key Compliance Areas
|
||||
- Filesystem hardening (CIS + STIG)
|
||||
- Password policy enforcement (CIS + STIG)
|
||||
- Audit daemon configuration (STIG)
|
||||
- Service hardening (CIS + STIG)
|
||||
- Network security implementation (STIG)
|
||||
- Logging and monitoring (STIG)
|
||||
- Package management disabling (custom requirement)

|

I need to initiate a new engineering project to build a highly secure, compliant Debian 13 (Trixie) installation ISO using a strict Docker-based workflow.
|
||||
|
||||
Please generate a detailed, technical **Specification Document** (in Markdown format) that outlines the requirements for this project. This document will serve as the blueprint for a Test-Driven Development (TDD) implementation.
|
||||
|
||||
The specification must cover the following requirements in detail:
|
||||
|
||||
**1. Target System Profile**
|
||||
* **OS:** Debian 13 (Trixie).
|
||||
* **Desktop:** Minimal IceWM Window Manager with LightDM Display Manager.
|
||||
* **Applications:** Remmina, WireGuard, Mousepad, PCManFM.
|
||||
* **Networking:** Wifi and Bluetooth must be permanently disabled (Kernel Blacklist).
|
||||
* **Connectivity:** No general internet access. All network traffic must be routed exclusively through a WireGuard tunnel.
|
||||
* **Firewall:** A "Deny All" default policy. The only allowed outbound traffic is UDP traffic to the specific IP/Port defined in the WireGuard configuration file. This must be dynamically configured by parsing the `.conf` file, not hardcoded.
|
||||
* **Authentication:** No auto-login. Usernames must be hidden in the Display Manager (Privacy Mode).
|
||||
* **Workflow:**
|
||||
* USB drives must be mountable to copy configurations.
|
||||
* Desktop shortcuts must exist to:
|
||||
1. Edit `/etc/wireguard/wg0.conf` (with root privileges via `pkexec`).
|
||||
2. Apply the VPN configuration and update the firewall rules dynamically.
|
||||
|
||||
**2. Installation Automation**
|
||||
* The build process must utilize `live-build`.
|
||||
* The ISO must use a `preseed.cfg` file to automate localization and software selection, **BUT** it must require manual interaction for:
|
||||
* Disk Partitioning.
|
||||
* Root Password Setup.
|
||||
* Non-root User Creation (User must be added to `sudo` group).
|
||||
|
||||
**3. Development Environment & Constraints**
|
||||
* **Host System:** The host environment is restricted. **NO Make**, NO Python, NO Ruby, NO build tools allowed on the host.
|
||||
* **Allowed Tools:** `docker`, `git`, `libvirt` (virt-install/virsh).
|
||||
* **Orchestration:** A single shell script wrapper (`run.sh`) is allowed on the host to invoke Docker commands.
|
||||
* **Builder Container:** All build tools (`live-build`, `debootstrap`) and testing tools must run inside a Docker container.
|
||||
* **Permissions:** All output files generated by the container must be owned by the user invoking Docker (not root).
|
||||
|
||||
**4. Quality Assurance & Testing (TDD)**
|
||||
* **Methodology:** Strict Test-Driven Development. The specification must define that tests are written *before* code.
|
||||
* **Testing Tools:** `bats-core` for testing, `shellcheck` for linting.
|
||||
* **Coverage:** 100% code coverage is mandatory (Unit tests for logic, Integration tests for ISO generation).
|
||||
* **Code Standards:** All Bash scripts must run in Strict Mode (`set -euo pipefail`).
|
||||
|
||||
**5. Compliance (CMMC / FedRAMP / STIG)**
|
||||
* The specification must demand the inclusion of a **Compliance Matrix** (`COMPLIANCE.md`).
|
||||
* This matrix must map specific STIG IDs and CIS Benchmark controls (e.g., disabling unused filesystems, enforcing strong passwords, configuring auditd) to specific configuration hooks in the build process.
|
||||
|
||||
**6. Output Format**
|
||||
* Provide the complete project structure (files and directories).
|
||||
* Provide the content logic for:
|
||||
* `run.sh` (Host wrapper).
|
||||
* `Dockerfile` (Build/Test environment).
|
||||
* `tests/` (BATS test structure).
|
||||
* `config/hooks/live/` (Security hardening and firewall scripts).
|
||||
* `src/` (Internal build scripts).
|
||||
|
||||
Please generate this comprehensive specification document now.

# Prompts cache
|

|
||||
## Prompt 1
|
||||
|
||||
|
||||
Will all of the code work with the current directory structure?
|
||||
|
||||
Will the code ONLY use docker containers/volumes for ALL WORK?
|
||||
|
||||
Will the code use knel-football-dev for all containers and volumes?
|
||||
|
||||
The only thing that is allowed to be written into the directory tree is the final fully customized ISO.
|
||||
That artifact must be git ignored.
|
||||
|
||||
Triple check the entire directory tree for compliance with all the above.
|
||||
|
||||
|
||||
## Prompt 2
|
||||
|
||||
Examine this entire project , the entire directory tree.
|
||||
|
||||
1) Review the specification located in docs/football-spec.md. That is the authority for this project.
|
||||
2) Review AGENTS.md. It has important instructions (like that all work should be done in docker containers/volumes, frequent commit/push etc).
|
||||
3) Check that the code complies with the specification. Fix any gaps. The specification may have outdate file paths. Make sure the specification is updated to match the current on disk reality.
|
||||
4) Check that the code is using best practices. Run (in a docker container) shellcheck/shellfmt . Fix all issues found. Pull docker images with those tools and use those docker images in ephermal containers todo the checks
|
||||
5) Build the ISO and boot the libvirt VM with it so i can validate the functionality

# KNEL-Football Security Model
|
||||
|
||||
## Overview
|
||||
|
||||
The KNEL-Football security model implements a defense-in-depth approach to create a highly secure, compliant Debian 13 operating system for tier0 infrastructure access.
|
||||
|
||||

||||
**License: GNU Affero General Public License v3.0 only**
|
||||
|
||||
## Security Architecture
|
||||
|
||||
### Core Principles
|
||||
|
||||
1. **Least Privilege** - Users and processes have only necessary permissions
|
||||
2. **Defense in Depth** - Multiple layers of security controls
|
||||
3. **Zero Trust** - No implicit trust, all access must be authorized
|
||||
4. **Immutability** - System configuration is not easily modifiable
|
||||
5. **Minimal Attack Surface** - Only necessary services and packages included
|
||||
|
||||
### System Hardening Layers
|
||||
|
||||
#### 1. Boot Security Layer
|
||||
|
||||
- **UEFI-Only Boot** - No legacy BIOS support prevents boot attacks
|
||||
- **Secure Boot** - Cryptographic verification of bootloader and kernel
|
||||
- **Measured Boot** - Boot chain integrity measurement and attestation
|
||||
|
||||
#### 2. Network Security Layer
|
||||
|
||||
- **Network Isolation** - No general internet access
|
||||
- **VPN-Only Access** - WireGuard tunnel required for all network traffic
|
||||
- **Firewall Hardening** - Default deny policy with specific rules
|
||||
- **Wireless Disabled** - WiFi and Bluetooth permanently disabled
|
||||
- **Dynamic Configuration** - Firewall rules adapt to WireGuard endpoints
|
||||
|
||||
#### 3. System Security Layer
|
||||
|
||||
- **Kernel Module Blacklisting** - Prevents loading of dangerous modules
|
||||
- **Service Hardening** - Unnecessary services disabled
|
||||
- **Process Isolation** - Application sandboxing where applicable
|
||||
- **Resource Limits** - Prevent resource exhaustion attacks
|
||||
- **Audit Logging** - Comprehensive system activity monitoring
|
||||
|
||||
#### 4. Access Control Layer
|
||||
|
||||
- **Strong Authentication** - 14-character minimum password policy
|
||||
- **No Auto-Login** - Manual authentication required
