# Football - Minimal Debian Secure Access System
|
||||
|
||||
Fully self contained , very stripped and locked down Debian image intended for deployment onto physical access only system (Dell Laptop) (called football-(x) to be used for remote (RDP) access to another high security physical system (highside) which is a privileged access workstation in the KNEL server room.
|
||||
Fully self-contained, stripped-down, and locked-down Debian image intended for deployment onto physical access-only systems (Dell Laptop) called football-(x). Used for remote RDP access to high-security physical systems (highside) which are privileged access workstations in the KNEL server room.
|
||||
|
||||
## Overview
|
||||
|
||||
Football is a minimal Debian system designed for secure remote access to privileged infrastructure. It enforces strict network controls where **ALL traffic must pass through a WireGuard VPN tunnel**, with direct network access completely blocked.
|
||||
|
||||
## Architecture
|
||||
|
||||
### Security Model
|
||||
|
||||
- **Zero remote access**: No SSH, telnet, or any inbound services
|
||||
- **WireGuard-only networking**: All traffic routed through mandatory VPN tunnel
|
||||
- **Secure Boot enforced**: Kernel and bootloader signatures verified
|
||||
- **Minimal attack surface**: Only IceWM and Remmina installed
|
||||
- **Local console only**: No remote administration capabilities
|
||||
|
||||
### Network Configuration
|
||||
|
||||
```
|
||||
Physical Interface (eth0)
|
||||
├─ DHCP: Allowed (for IP acquisition)
|
||||
└─ WireGuard: ONLY allowed connection to configured endpoint
|
||||
└─ Endpoint: WG_ENDPOINT_IP:WG_ENDPOINT_PORT (configurable)
|
||||
|
||||
WireGuard Interface (wg0)
|
||||
└─ ALL outbound traffic
|
||||
└─ VPN endpoint → PAW (Privileged Access Workstation)
|
||||
```
|
||||
|
||||
### Firewall Rules
|
||||
|
||||
- **INPUT**: DROP (except lo, WireGuard keepalive, and DHCP)
|
||||
- **OUTPUT**: DROP on eth0 (except to WireGuard endpoint)
|
||||
- **FORWARD**: DROP
|
||||
- **OUTPUT on wg0**: ACCEPT (all VPN traffic)
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Prerequisites
|
||||
|
||||
```bash
|
||||
# Install build dependencies
|
||||
sudo apt-get install debootstrap qemu-utils kpartx squashfs-tools
|
||||
```
|
||||
|
||||
### Generate WireGuard Keys
|
||||
|
||||
```bash
|
||||
# Generate client key pair
|
||||
wg genkey | tee client-private.key | wg pubkey > client-public.key
|
||||
|
||||
# Add client public key to WireGuard server configuration
|
||||
# Server configuration (on your WireGuard VPN server):
|
||||
# [Peer]
|
||||
# PublicKey = $(cat client-public.key)
|
||||
# AllowedIPs = 10.100.0.2/32
|
||||
```
|
||||
|
||||
### Configure Build
|
||||
|
||||
Edit `build.sh` and set the following variables:
|
||||
|
||||
```bash
|
||||
WG_ENDPOINT_IP="192.0.2.1" # Your WireGuard server IP
|
||||
WG_ENDPOINT_PORT="51820" # Your WireGuard server port
|
||||
WG_PRIVATE_KEY="$(cat client-private.key)" # Client private key
|
||||
WG_PUBLIC_KEY="<SERVER_PUBLIC_KEY>" # Server public key
|
||||
```
|
||||
|
||||
### Build Image
|
||||
|
||||
```bash
|
||||
./build.sh
|
||||
```
|
||||
|
||||
This creates:
|
||||
- `output/football-physical.img` - Raw image for physical hardware
|
||||
- `output/football-vm.qcow2` - QCOW2 image for virtual machines
|
||||
|
||||
### Deploy
|
||||
|
||||
#### Virtual Machine
|
||||
|
||||
```bash
|
||||
qemu-system-x86_64 \
|
||||
-m 2048 \
|
||||
-drive file=output/football-vm.qcow2,format=qcow2
|
||||
```
|
||||
|
||||
#### Physical System
|
||||
|
||||
1. Write raw image to USB or disk:
|
||||
```bash
|
||||
sudo dd if=output/football-physical.img of=/dev/sdX bs=4M status=progress
|
||||
```
|
||||
|
||||
2. Boot system with UEFI Secure Boot enabled
|
||||
|
||||
3. Change default user password (`changeme`)
|
||||
|
||||

```
|
||||
|
||||
## Security Features
|
||||
|
||||
### Hardening Measures
|
||||
|
||||
1. **Network Isolation**
|
||||
- All inbound traffic blocked
|
||||
- Only WireGuard traffic allowed on physical interface
|
||||
- Mandatory VPN tunnel for all outbound traffic
|
||||
|
||||
2. **Service Restrictions**
|
||||
- SSH server disabled and masked
|
||||
- All remote access services removed
|
||||
- Bluetooth disabled
|
||||
- Unnecessary kernel modules disabled
|
||||
|
||||
3. **Secure Boot**
|
||||
- GRUB locked with password protection
|
||||
- Kernel lockdown mode enabled
|
||||
- Signed bootloader (shim-signed)
|
||||
- EFI variables write-protected
|
||||
|
||||
4. **Application Whitelisting**
|
||||
- Only IceWM and Remmina installed
|
||||
- No development tools
|
||||
- Minimal command-line utilities
|
||||
|
||||
5. **System Hardening**
|
||||
- AppArmor enforcing
|
||||
- Fail2Ban enabled
|
||||
- Auditd logging
|
||||
- Core dumps disabled
|
||||
- Strict umask (077)
|
||||
|
||||
### Firewall Rules (Detailed)
|
||||
|
||||
```bash
|
||||
# IPv4 Rules
|
||||
iptables -P INPUT DROP
|
||||
iptables -P FORWARD DROP
|
||||
iptables -P OUTPUT DROP
|
||||
|
||||
# Allow loopback
|
||||
iptables -A INPUT -i lo -j ACCEPT
|
||||
iptables -A OUTPUT -o lo -j ACCEPT
|
||||
|
||||
# Allow WireGuard to endpoint on eth0
|
||||
iptables -A OUTPUT -o eth0 -d $WG_ENDPOINT_IP \
|
||||
-p udp --dport $WG_ENDPOINT_PORT -j ACCEPT
|
||||
iptables -A INPUT -i eth0 -s $WG_ENDPOINT_IP \
|
||||
-p udp --sport $WG_ENDPOINT_PORT -j ACCEPT
|
||||
|
||||
# Allow DHCP on eth0
|
||||
iptables -A OUTPUT -o eth0 -p udp --dport 67 -j ACCEPT
|
||||
iptables -A INPUT -i eth0 -p udp --sport 67 -j ACCEPT
|
||||
|
||||
# Allow ALL traffic on WireGuard interface
|
||||
iptables -A INPUT -i wg0 -j ACCEPT
|
||||
iptables -A OUTPUT -o wg0 -j ACCEPT
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Default User
|
||||
|
||||
- **Username**: `user`
|
||||
- **Password**: `changeme` (CHANGE IMMEDIATELY!)
|
||||
|
||||
### Automatic Startup
|
||||
|
||||
1. Login triggers automatic IceWM start
|
||||
2. Remmina launches automatically
|
||||
3. WireGuard tunnel establishes automatically
|
||||
4. Use Remmina to connect to PAW
|
||||
|
||||
### Remmina Configuration
|
||||
|
||||
Create Remmina profiles in:
|
||||
- Path: `/home/user/.local/share/remmina/`
|
||||
- Protocol: RDP or VNC (as needed)
|
||||
- Server: PAW internal IP via WireGuard
|
||||
|
||||
### System Administration
|
||||
|
||||
**Local console access only:**
|
||||
|
||||
```bash
|
||||
# Check WireGuard status
|
||||
sudo wg show
|
||||
|
||||
# View firewall rules
|
||||
sudo iptables -L -n -v
|
||||
|
||||
# Check logs
|
||||
sudo journalctl -u wg-quick@wg0
|
||||
sudo journalctl -u block-remote-access
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### WireGuard Connection Fails
|
||||
|
||||
1. Verify endpoint IP and port
|
||||
2. Check firewall rules allow WireGuard
|
||||
3. Verify keys are correctly configured
|
||||
4. Check WireGuard server logs
|
||||
|
||||
### Network Blocked
|
||||
|
||||
1. Confirm WireGuard interface is up: `ip link show wg0`
|
||||
2. Check firewall: `sudo iptables -L -n -v`
|
||||
3. Verify WireGuard config: `sudo wg show`
|
||||
|
||||
### Secure Boot Issues
|
||||
|
||||
1. Ensure UEFI is enabled
|
||||
2. Verify Microsoft UEFI CA is installed
|
||||
3. Check Secure Boot status: `mokutil --sb-state`
|
||||
|
||||
### System Won't Boot
|
||||
|
||||
1. Verify UEFI boot mode (not legacy BIOS)
|
||||
2. Check GRUB installation
|
||||
3. Review kernel logs from boot
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### Customizing the Build
|
||||
|
||||
Edit `config/packages.list` to add/remove packages
|
||||
Modify `chroot-overlay/` to customize system files
|
||||
|
||||
### Changing Image Size
|
||||
|
||||
Edit `build.sh`:
|
||||
```bash
|
||||
DISK_SIZE_MB=8192 # Change to desired size in MB
|
||||
```
|
||||
|
||||
### Multiple Deployment Profiles
|
||||
|
||||
Create different `build.sh` variants with different configurations for various deployment scenarios.
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Before Deployment
|
||||
|
||||
1. ✅ Generate unique WireGuard keys per deployment
|
||||
2. ✅ Change default password
|
||||
3. ✅ Verify Secure Boot configuration
|
||||
4. ✅ Test WireGuard connection
|
||||
5. ✅ Verify firewall rules
|
||||
6. ✅ Configure PAW connection in Remmina
|
||||
|
||||
### During Operation
|
||||
|
||||
1. ✅ Monitor WireGuard connection
|
||||
2. ✅ Review audit logs regularly
|
||||
3. ✅ Keep system updated (manual, controlled updates)
|
||||
4. ✅ Physical security of device
|
||||
|
||||
### Incident Response
|
||||
|
||||
If compromise suspected:
|
||||
1. Isolate system physically
|
||||
2. Preserve logs and memory dump
|
||||
3. Contact security team
|
||||
4. Destroy/rebuild system from scratch

# Football Secure Access System
|
||||
|
||||
This system is configured for secure access to remote privileged access workstations through a WireGuard VPN tunnel.
|
||||
|
||||
**SYSTEM CHARACTERISTICS:**
|
||||
- Remote access: DISABLED (no SSH, no network services)
|
||||
- Local console access only
|
||||
- Automatic IceWM window manager startup
|
||||
- Remmina remote desktop client
|
||||
- Secure Boot enforced
|
||||
- **ALL network traffic MUST go through WireGuard VPN**
|
||||
- **Direct network access BLOCKED - only WireGuard allowed**
|
||||
|
||||
**NETWORK CONFIGURATION:**
|
||||
- Physical interface (eth0): ONLY allows WireGuard to configured endpoint
|
||||
- WireGuard tunnel (wg0): ALL outbound traffic goes through this tunnel
|
||||
- Inbound traffic: BLOCKED (except WireGuard keepalives)
|
||||
- DHCP: Allowed on eth0 only for initial IP acquisition
|
||||
|
||||
**USAGE:**
|
||||
1. Login with local user account
|
||||
2. IceWM and Remmina start automatically
|
||||
3. WireGuard tunnel is established automatically
|
||||
4. Use Remmina to connect to PAW (Privileged Access Workstation) through VPN
|
||||
5. Close Remmina when done
|
||||
6. System locks automatically on inactivity
|
||||
|
||||
**SECURITY:**
|
||||
- No remote administration permitted
|
||||
- All direct network connections blocked
|
||||
- Only WireGuard tunnel traffic allowed to configured endpoint
|
||||
- System logs all actions
|
||||
- Secure Boot verifies kernel integrity
|
||||
- Firewall strictly enforced
|
||||
|
||||
**WIREGUARD ENDPOINT:**
|
||||
- Configured during build (see build script variables)
|
||||
- Only endpoint allowed: WG_ENDPOINT_IP:WG_ENDPOINT_PORT
|
||||
- All traffic routes through VPN after connection
|
||||
|
||||
**CONTACT:**
|
||||
For system issues, contact infrastructure security team.
