+# 🔒 Delphi Database System - Security Setup Guide
+
+## ⚠️ CRITICAL: P0 Security Issues RESOLVED
+
+The following **CRITICAL SECURITY VULNERABILITIES** have been fixed:
+
+### ✅ **1. CORS Vulnerability Fixed**
+- **Issue**: `allow_origins=["*"]` allowed any website to access the API
+- **Fix**: CORS now requires specific domain configuration via `CORS_ORIGINS` environment variable
+- **Location**: `app/main.py:61-87`
+
+### ✅ **2. Hardcoded Passwords Removed** 
+- **Issue**: Default passwords `admin123` and `change-me` were hardcoded
+- **Fix**: All passwords now require secure environment variables
+- **Files Fixed**: `app/config.py`, `e2e/global-setup.js`, `playwright.config.js`, `docker-compose.dev.yml`, `scripts/init-container.sh`, `templates/login.html`
+
+### ✅ **3. Comprehensive Input Validation Added**
+- **Issue**: Upload endpoints lacked proper security validation
+- **Fix**: New `app/utils/file_security.py` module provides:
+  - File type validation using content inspection (not just extensions)
+  - File size limits to prevent DoS attacks
+  - Path traversal protection
+  - Malware pattern detection
+  - Filename sanitization
+- **Files Enhanced**: `app/api/documents.py`, `app/api/templates.py`, `app/api/admin.py`
+
+### ✅ **4. Path Traversal Protection Implemented**
+- **Issue**: File operations could potentially access files outside intended directories
+- **Fix**: Secure path generation with directory traversal prevention
+- **Implementation**: `FileSecurityValidator.generate_secure_path()`
+
+## 🚀 Quick Security Setup
+
+### 1. Generate Secure Environment Configuration
+
+```bash
+# Run the automated security setup script
+python scripts/setup-secure-env.py
+```
+
+This script will:
+- Generate a cryptographically secure 32+ character SECRET_KEY
+- Create a strong admin password
+- Configure CORS for your specific domains
+- Set up production-ready security settings
+- Create a secure `.env` file with proper permissions
+
+### 2. Manual Environment Setup
+
+If you prefer manual setup, copy `env-example.txt` to `.env` and configure:
+
+```bash
+# Copy the example file
+cp env-example.txt .env
+
+# Generate a secure secret key
+python -c "import secrets; print('SECRET_KEY=' + secrets.token_urlsafe(32))"
+
+# Generate a secure admin password  
+python -c "import secrets, string; print('ADMIN_PASSWORD=' + ''.join(secrets.choice(string.ascii_letters + string.digits + '!@#$%^&*') for _ in range(16)))"
+```
+
+### 3. Required Environment Variables
+
+**CRITICAL - Must be set before running:**
+
+```bash
+SECRET_KEY=your-32-plus-character-random-string
+ADMIN_PASSWORD=your-secure-admin-password
+CORS_ORIGINS=https://your-domain.com,https://www.your-domain.com
+```
+
+**Important - Should be configured:**
+
+```bash
+DEBUG=False                    # For production
+SECURE_COOKIES=True           # For HTTPS production
+DATABASE_URL=your-db-url      # For production database
+```
+
+## 🛡️ Security Features Implemented
+
+### File Upload Security
+- **File Type Validation**: Content-based MIME type detection (not just extensions)
+- **Size Limits**: Configurable per file category to prevent DoS
+- **Path Traversal Protection**: Secure path generation prevents directory escape
+- **Malware Detection**: Basic pattern scanning for malicious content
+- **Filename Sanitization**: Removes dangerous characters and path separators
+
+### Authentication Security
+- **Strong Password Requirements**: Environment-enforced secure passwords
+- **Secure Secret Management**: Cryptographically secure JWT secret keys
+- **No Hardcoded Credentials**: All secrets via environment variables
+
+### Network Security
+- **Restricted CORS**: Domain-specific origin restrictions
+- **Secure Headers**: Proper CORS header configuration
+- **Method Restrictions**: Limited to necessary HTTP methods
+
+## 🔍 Security Validation
+
+### Before Production Deployment
+
+Run this checklist to verify security:
+
+```bash
+# 1. Verify no hardcoded secrets
+grep -r "admin123\|change-me\|secret.*=" app/ --exclude-dir=__pycache__ || echo "✅ No hardcoded secrets found"
+
+# 2. Verify CORS configuration
+grep -n "allow_origins" app/main.py
+
+# 3. Verify .env file permissions
+ls -la .env | grep "^-rw-------" && echo "✅ .env permissions correct" || echo "❌ Fix .env permissions: chmod 600 .env"
+
+# 4. Test file upload validation
+curl -X POST http://localhost:8000/api/documents/upload/test-file \
+  -H "Authorization: Bearer your-token" \
+  -F "file=@malicious.exe" \
+  && echo "❌ Upload validation failed" || echo "✅ Upload validation working"
+```
+
+### Security Test Results Expected
+
+- ✅ No hardcoded passwords in codebase
+- ✅ CORS origins restricted to specific domains  
+- ✅ File uploads reject dangerous file types
+- ✅ Path traversal attempts blocked
+- ✅ Large file uploads rejected
+- ✅ .env file has restrictive permissions (600)
+
+## 🚨 Production Security Checklist
+
+### Required Before Going Live
+
+- [ ] **SECRET_KEY** generated with 32+ cryptographically random characters
+- [ ] **ADMIN_PASSWORD** set to strong password (12+ chars, mixed case, symbols)
+- [ ] **CORS_ORIGINS** configured for specific production domains (not localhost)
+- [ ] **DEBUG=False** set for production
+- [ ] **SECURE_COOKIES=True** if using HTTPS (required for production)
+- [ ] **Database backups** configured and tested
+- [ ] **HTTPS enabled** with valid SSL certificates
+- [ ] **.env file** has 600 permissions and is not in version control
+- [ ] **Log monitoring** configured for security events
+- [ ] **Rate limiting** configured (next priority)
+- [ ] **Security audit** completed by security professional
+
+### Ongoing Security Maintenance
+
+- 🔄 **Rotate SECRET_KEY** every 90 days using `scripts/rotate-secret-key.py`
+- 🔄 **Change admin password** every 90 days
+- 📊 **Monitor logs** for security events
+- 🔍 **Regular security scans** of dependencies
+- 📋 **Keep software updated** (Python, FastAPI, dependencies)
+
+## 📞 Next Steps
+
+The P0 Critical Security Issues are now **RESOLVED**. The system is significantly more secure, but you should continue with P1 High Priority items:
+
+1. **Rate Limiting** - Implement API rate limiting to prevent abuse
+2. **Security Headers** - Add HSTS, CSP, X-Frame-Options headers  
+3. **Session Management** - Enhance JWT token management
+4. **Database Security** - Review SQL injection prevention
+5. **Security Monitoring** - Implement intrusion detection
+
+For immediate deployment readiness, ensure all items in the **Production Security Checklist** above are completed.

+
+**🔒 Remember**: Security is an ongoing process. This setup addresses the most critical vulnerabilities, but regular security reviews and updates are essential for a production system handling sensitive legal and financial data.
