# 🛡️ Security Hardening Complete
|
||||
|
||||
## Overview
|
||||
|
||||
Comprehensive security improvements have been applied to the Church Music Database application to meet production security standards.
|
||||
|
||||
## ✅ Completed Security Enhancements
|
||||
|
||||
### 1. Rate Limiting (Token Bucket Algorithm)
|
||||
|
||||
**File:** `backend/rate_limiter.py`
|
||||
|
||||
All API endpoints now have rate limiting to prevent abuse:
|
||||
|
||||
| Endpoint | Limit (req/min) | Purpose |
|
||||
|----------|-----------------|---------|
|
||||
| `/api/admin/restore` | 5 | Admin-only, highly sensitive |
|
||||
| `/api/upload_lyric` | 10 | File upload, resource-intensive |
|
||||
| `/api/export/<plan_id>` | 10 | PDF generation, CPU-intensive |
|
||||
| `/api/search_external` | 20 | External API calls |
|
||||
| `/api/profiles` (POST) | 60 | User profile creation |
|
||||
| `/api/plans`, `/api/songs` | 30-60 | CRUD operations |
|
||||
| `/api/providers`, `/api/health` | 60 | Metadata endpoints |
|
||||
|
||||
**Features:**
|
||||
|
||||
- ✅ Thread-safe implementation with locks
|
||||
- ✅ Per-client tracking by IP address
|
||||
- ✅ Automatic token refill (1 token/second)
|
||||
- ✅ `Retry-After` headers for rate-limited clients
|
||||
- ✅ `X-RateLimit-*` headers for monitoring
|
||||
|
||||
**Usage:**
|
||||
|
||||
```python
|
||||
from rate_limiter import rate_limit
|
||||
|
||||
@app.route('/api/sensitive')
|
||||
@rate_limit(max_per_minute=10)
|
||||
def sensitive_operation():
|
||||
# Your code here
|
||||
```
|
||||
|
||||
### 2. Input Validation Framework
|
||||
|
||||
**File:** `backend/validators.py`
|
||||
|
||||
Comprehensive validation schemas for all data models:
|
||||
|
||||
**Profile Schema:**
|
||||
|
||||
- Name: 1-200 chars, alphanumeric + spaces/punctuation
|
||||
- Email: Valid RFC 5322 format
|
||||
- Phone: 7-20 chars, digits/spaces/dashes/parentheses
|
||||
- Notes: Max 5000 chars
|
||||
|
||||
**Song Schema:**
|
||||
|
||||
- Title: 1-500 chars, required
|
||||
- Artist/Band: 1-200 chars, optional
|
||||
- Lyrics: Max 100,000 chars
|
||||
- Chords: Max 50,000 chars
|
||||
|
||||
**Plan Schema:**
|
||||
|
||||
- Date: ISO 8601 format (YYYY-MM-DD)
|
||||
- Profile ID: Valid UUID v4
|
||||
- Notes: Max 5000 chars
|
||||
|
||||
**Validation Functions:**
|
||||
|
||||
- `validate_string()` - Length, pattern, XSS prevention
|
||||
- `validate_email()` - RFC 5322 compliance
|
||||
- `sanitize_filename()` - Path traversal prevention
|
||||
- `validate_uuid()` - UUID format verification
|
||||
|
||||
**Usage:**
|
||||
|
||||
```python
|
||||
from validators import validate_request_data, PROFILE_SCHEMA
|
||||
|
||||
@app.route('/api/profiles', methods=['POST'])
|
||||
@validate_request_data(PROFILE_SCHEMA)
|
||||
def create_profile():
|
||||
# Request data is already validated
|
||||
```
|
||||
|
||||
### 3. Enhanced Security Headers
|
||||
|
||||
**File:** `backend/app.py` - `set_security_headers()`
|
||||
|
||||
Added comprehensive HTTP security headers:
|
||||
|
||||
```python
|
||||
X-Content-Type-Options: nosniff
|
||||
X-Frame-Options: DENY
|
||||
X-XSS-Protection: 1; mode=block
|
||||
Strict-Transport-Security: max-age=31536000; includeSubDomains
|
||||
Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline' ...
|
||||
X-RateLimit-Limit: 60
|
||||
X-RateLimit-Remaining: 59
|
||||
Retry-After: 30 (when rate limited)
|
||||
```
|
||||
|
||||
### 4. CORS Configuration Hardening
|
||||
|
||||
**File:** `backend/app.py`
|
||||
|
||||
**Before:** Wildcard origins (*)
|
||||
**After:** Strict allow-list
|
||||
|
||||
```python
|
||||
ALLOWED_ORIGINS = [
|
||||
"http://localhost:5100",
|
||||
"https://houseofprayer.ddns.net"
|
||||
]
|
||||
```
|
||||
|
||||
**Configuration:**
|
||||
|
||||
- ✅ Credentials support: `supports_credentials=True`
|
||||
- ✅ Restricted methods: GET, POST, PUT, DELETE, OPTIONS
|
||||
- ✅ Restricted headers: Content-Type, Authorization
|
||||
- ✅ No wildcard origins
|
||||
|
||||
### 5. Environment File Protection
|
||||
|
||||
**Files:** `.gitignore`, `backend/.env`
|
||||
|
||||
**Actions Taken:**
|
||||
|
||||
1. Created `.gitignore` with patterns:
|
||||
|
||||
```
|
||||
*.env
|
||||
.env.*
|
||||
**/.env
|
||||
secrets/
|
||||
*.key
|
||||
```
|
||||
|
||||
2. Set `.env` permissions: `chmod 0600` (owner read/write only)
|
||||
3. Created `.env.template` for safe distribution
|
||||
4. Verified no `.env` files in git history
|
||||
|
||||
**Security Check Output:**
|
||||
|
||||
```
|
||||
✓ .env permissions: 0600 (secure)
|
||||
✓ .gitignore protects .env files
|
||||
⚠ Weak database password detected: "postgres"
|
||||
✓ SECRET_KEY length adequate (64 chars)
|
||||
```
|
||||
|
||||
### 6. Database Backup Automation
|
||||
|
||||
**File:** `backup-database.sh`
|
||||
|
||||
**Features:**
|
||||
|
||||
- ✅ Automated PostgreSQL backups with `pg_dump`
|
||||
- ✅ Gzip compression for space efficiency
|
||||
- ✅ 7-day retention policy with automatic cleanup
|
||||
- ✅ Backup integrity verification (gzip -t)
|
||||
- ✅ Symbolic link to latest backup
|
||||
- ✅ Comprehensive logging to `backups/backup.log`
|
||||
- ✅ Size reporting and error handling
|
||||
|
||||
**Cron Schedule:**
|
||||
|
||||
```bash
|
||||
# Daily backup at 2 AM
|
||||
0 2 * * * /media/pts/Website/Church_HOP_MusicData/backup-database.sh
|
||||
|
||||
# Weekly full backup on Sundays at 3 AM (30-day retention)
|
||||
0 3 * * 0 /media/pts/Website/Church_HOP_MusicData/backup-database.sh && \
|
||||
cp backups/church_songlyric_latest.sql.gz backups/weekly_$(date +%Y%m%d).sql.gz
|
||||
```
|
||||
|
||||
**Usage:**
|
||||
|
||||
```bash
|
||||
# Manual backup
|
||||
./backup-database.sh
|
||||
|
||||
# Restore from backup
|
||||
gunzip -c backups/church_songlyric_20240101_020000.sql.gz | \
|
||||
psql -h 192.168.10.130 -U songlyric_user -d church_songlyric
|
||||
|
||||
# Restore from latest
|
||||
gunzip -c backups/church_songlyric_latest.sql.gz | \
|
||||
psql -h 192.168.10.130 -U songlyric_user -d church_songlyric
|
||||
```
|
||||
|
||||
### 7. Enhanced Process Management
|
||||
|
||||
**Files:** `cleanup-ports.sh`, `stop-dev-mode.sh`
|
||||
|
||||
**Improvements:**
|
||||
|
||||
- ✅ Detect and kill development servers (react-scripts, webpack-dev-server)
|
||||
- ✅ Force kill with `SIGKILL` if graceful shutdown fails
|
||||
- ✅ Prevent port conflicts (5100, 8080, 3000, 3001)
|
||||
- ✅ Comprehensive process cleanup before production deployment
|
||||
|
||||
### 8. Logging Infrastructure
|
||||
|
||||
**File:** `backend/app.py`
|
||||
|
||||
Added centralized logging:
|
||||
|
||||
```python
|
||||
import logging
|
||||
|
||||
logging.basicConfig(
|
||||
level=logging.INFO,
|
||||
format='%(asctime)s [%(levelname)s] %(name)s: %(message)s',
|
||||
handlers=[
|
||||
logging.FileHandler('backend/app.log'),
|
||||
logging.StreamHandler()
|
||||
]
|
||||
)
|
||||
|
||||
logger = logging.getLogger(__name__)
|
||||
logger.info("Application started")
|
||||
```
|
||||
|
||||
## 🔴 Critical Issues Identified (Action Required)
|
||||
|
||||
### 1. Weak Database Password
|
||||
|
||||
**Issue:** Database password is "postgres" (common default)
|
||||
**Risk:** Brute-force attacks, unauthorized access
|
||||
**Priority:** HIGH
|
||||
|
||||
**Fix:**
|
||||
|
||||
```bash
|
||||
# Generate strong password (32 chars)
|
||||
openssl rand -base64 32
|
||||
|
||||
# Update .env file
|
||||
POSTGRESQL_URI=postgresql://songlyric_user:NEW_STRONG_PASSWORD@192.168.10.130:5432/church_songlyric
|
||||
|
||||
# Update PostgreSQL user password
|
||||
psql -h 192.168.10.130 -U postgres -c "ALTER USER songlyric_user PASSWORD 'NEW_STRONG_PASSWORD';"
|
||||
|
||||
# Restart backend service
|
||||
sudo systemctl restart church-music-backend.service
|
||||
```
|
||||
|
||||
### 2. Client-Side Authentication
|
||||
|
||||
**Issue:** Password hash hardcoded in `frontend/src/App.js`
|
||||
**Risk:** Anyone can view source and bypass authentication
|
||||
**Priority:** CRITICAL
|
||||
|
||||
**Recommended Solution:**
|
||||
|
||||
1. Implement server-side JWT authentication
|
||||
2. Store passwords hashed with bcrypt (backend)
|
||||
3. Issue short-lived access tokens (15 min)
|
||||
4. Implement refresh token rotation
|
||||
5. Add session management with Redis
|
||||
|
||||
**Immediate Mitigation:**
|
||||
|
||||
- Restrict frontend URL to internal network only
|
||||
- Add IP whitelisting in Nginx
|
||||
- Monitor access logs for suspicious activity
|
||||
|
||||
### 3. Monolithic Architecture
|
||||
|
||||
**Issue:** `app.py` (935 lines), `App.js` (7661 lines)
|
||||
**Risk:** Hard to maintain, test, and debug
|
||||
**Priority:** MEDIUM
|
||||
|
||||
