# Phase 1: Foundation - COMPLETE ✓

**Date Completed:** 2025-11-13

Phase 1 of the SneakyScanner roadmap has been successfully implemented. This document summarizes what was delivered and how to use the new infrastructure.

---

## ✓ Deliverables Completed

### 1. Database Schema & Models
- **SQLAlchemy models** for all 11 database tables (`web/models.py`)
  - Core tables: `Scan`, `ScanSite`, `ScanIP`, `ScanPort`, `ScanService`, `ScanCertificate`, `ScanTLSVersion`
  - Scheduling tables: `Schedule`, `Alert`, `AlertRule`
  - Configuration: `Setting`
- **Alembic migrations** system configured (`migrations/`)
- **Initial migration** created (`migrations/versions/001_initial_schema.py`)

### 2. Settings System with Encryption
- **SettingsManager** class with CRUD operations (`web/utils/settings.py`)
- **Automatic encryption** for sensitive values (SMTP passwords, API tokens)
- **PasswordManager** for bcrypt password hashing
- **Default settings initialization** for SMTP, authentication, retention policies

### 3. Flask Application Structure
- **Flask app factory** pattern implemented (`web/app.py`)
- **API blueprints** for all major endpoints:
  - `/api/scans` - Scan management (stub for Phase 2)
  - `/api/schedules` - Schedule management (stub for Phase 3)
  - `/api/alerts` - Alert management (stub for Phase 4)
  - `/api/settings` - Settings API (functional in Phase 1!)
- **Error handlers** for common HTTP status codes
- **CORS support** for API access
- **Logging** to file and console
- **Database session management** with scoped sessions

### 4. Database Initialization
- **init_db.py** script for easy database setup
- Supports both Alembic migrations and direct table creation
- Password setting during initialization
- Database verification and settings display

### 5. Docker Support
- **Updated Dockerfile** with Flask dependencies
- **docker-compose-web.yml** for running the web application
- Separate service definition for database initialization
- Volume mounts for persistence (database, output, logs)

### 6. Validation & Testing
- **validate_phase1.py** script to verify all deliverables
- Validates directory structure, files, Python syntax, models, and API endpoints
- All checks passing ✓

## 🚀 Getting Started

### Option 1: Local Development (without Docker)

#### 1. Install Dependencies

```bash
# Install Flask and web dependencies
pip install -r requirements-web.txt
```

#### 2. Initialize Database

```bash
# Create database and set password
python3 init_db.py --password YOUR_SECURE_PASSWORD

# Verify database
python3 init_db.py --verify-only
```

#### 3. Run Flask Application

```bash
# Run development server
python3 -m web.app

# Application will be available at http://localhost:5000
```

#### 4. Test API Endpoints

```bash
# Health check
curl http://localhost:5000/api/settings/health

# Get all settings (sanitized)
curl http://localhost:5000/api/settings

# Get specific setting
curl http://localhost:5000/api/settings/smtp_server

# Update a setting
curl -X PUT http://localhost:5000/api/settings/smtp_server \
  -H "Content-Type: application/json" \
  -d '{"value": "smtp.gmail.com"}'

# Set application password
curl -X POST http://localhost:5000/api/settings/password \
  -H "Content-Type: application/json" \
  -d '{"password": "newsecurepassword"}'
```

---

### Option 2: Docker Deployment

#### 1. Build Docker Image

```bash
docker-compose -f docker-compose-web.yml build
```

#### 2. Initialize Database (one-time)

```bash
# Create data directory
mkdir -p data

# Initialize database
docker-compose -f docker-compose-web.yml run --rm init-db --password YOUR_SECURE_PASSWORD
```

#### 3. Run Web Application

```bash
# Start Flask web server
docker-compose -f docker-compose-web.yml up -d web

# View logs
docker-compose -f docker-compose-web.yml logs -f web
```

#### 4. Access Application

- Encryption key auto-generated and stored in settings table
- Can be overridden via `SNEAKYSCANNER_ENCRYPTION_KEY` environment variable

### Password Hashing
- **Bcrypt** for application password hashing (work factor 12)
- Password stored as irreversible hash in settings table
- Minimum 8 characters enforced

### Session Management
- Flask sessions with configurable `SECRET_KEY`
- Set via environment variable or config

---

## 📊 Database Schema

### Core Tables
- **scans** - Scan metadata and status
- **scan_sites** - Site groupings
- **scan_ips** - IP addresses scanned
- **scan_ports** - Discovered ports
- **scan_services** - Service detection results
- **scan_certificates** - SSL/TLS certificates
- **scan_tls_versions** - TLS version support

### Scheduling & Alerts
- **schedules** - Cron-like scan schedules
- **alerts** - Alert history
- **alert_rules** - Alert rule definitions

### Configuration
- **settings** - Application settings (key-value store)

All tables include proper foreign keys, indexes, and cascade delete rules.

---

## 🧪 Validation

Run the Phase 1 validation script to verify everything is in place:

```bash
python3 validate_phase1.py
```

Expected output:
```
✓ All Phase 1 validation checks passed!
```

---

## 🔧 Environment Variables

Configure the Flask app via environment variables:

```bash
# Flask configuration
export FLASK_ENV=development
export FLASK_DEBUG=true
export FLASK_HOST=0.0.0.0
export FLASK_PORT=5000

# Database
export DATABASE_URL=sqlite:///./sneakyscanner.db

# Security
export SECRET_KEY=your-secret-key-here
export SNEAKYSCANNER_ENCRYPTION_KEY=your-encryption-key-here

# CORS (comma-separated origins)
export CORS_ORIGINS=http://localhost:3000,https://your-domain.com

# Logging
export LOG_LEVEL=INFO
```

Or use a `.env` file (supported via `python-dotenv`).

## 🎯 Next Steps: Phase 2

Phase 2 will implement:
1. **REST API for scans** - Trigger scans, list history, get results
2. **Background job queue** - APScheduler for async scan execution
3. **Authentication** - Flask-Login for session management
4. **Scanner integration** - Save scan results to database
5. **Docker Compose deployment** - Production-ready setup

Estimated timeline: 2 weeks (as per roadmap)

## 🐛 Troubleshooting

### Database Issues
```bash
# Reset database
rm sneakyscanner.db
python3 init_db.py --password newpassword

# Check database
sqlite3 sneakyscanner.db ".schema"
```

### Flask Won't Start
```bash
# Check dependencies installed
pip list | grep -i flask

# Check syntax errors
python3 validate_phase1.py

# Run with debug output
FLASK_DEBUG=true python3 -m web.app
```

### Encryption Errors
```bash
# Generate new encryption key
python3 -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"

# Set in environment
export SNEAKYSCANNER_ENCRYPTION_KEY="your-key-here"
```
