## 📝 Modified Files

### Forms (8 files) - Added CSRF Tokens
```
trip-details.php
driver_training.php
bush_mechanics.php
rescue_recovery.php
campsite_booking.php
membership_application.php
campsites.php
login.php
```

**Change Pattern:**
```php
<!-- Add before form submit -->
<input type="hidden" name="csrf_token" value="<?php echo \Middleware\CsrfMiddleware::getToken(); ?>">
```

### Processors (10+ files) - Added CSRF Validation & Rate Limiting
```
process_booking.php
process_trip_booking.php
process_course_booking.php
process_camp_booking.php
process_membership_payment.php
process_application.php
process_signature.php
process_eft.php
add_campsite.php
validate_login.php
send_reset_link.php
```

**Change Patterns:**

**CSRF Validation:**
```php
use Middleware\CsrfMiddleware;
CsrfMiddleware::requireToken($_POST);  // Dies if invalid
```

**Rate Limiting:**
```php
use Middleware\RateLimitMiddleware;
if (RateLimitMiddleware::isLimited('login', 5, 900)) {
    die(json_encode(['success' => false, 'message' => 'Too many attempts. Try again later.']));
}
RateLimitMiddleware::incrementAttempt('login', 900);
```

**Session Regeneration:**
```php
use Services\AuthenticationService;
AuthenticationService::regenerateSession();  // After successful login
```

**Audit Logging:**
```php
use Services\AuditLogger;
AuditLogger::logLogin($email, true);  // Success
AuditLogger::logLogin($email, false, 'Invalid password');  // Failure
```

## 🗄️ Database Schema

### New Table: `audit_logs`
```sql
CREATE TABLE audit_logs (
  log_id INT AUTO_INCREMENT PRIMARY KEY,
  user_id INT,
  action VARCHAR(50),
  status VARCHAR(20),
  ip_address VARCHAR(45),
  details JSON,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (user_id) REFERENCES users(user_id) ON DELETE SET NULL,
  
  INDEX idx_user_id (user_id),
  INDEX idx_action (action),
  INDEX idx_status (status),
  INDEX idx_created_at (created_at),
  INDEX idx_ip_address (ip_address),
  INDEX idx_user_created (user_id, created_at)
);
```

**Columns:**
| Column | Type | Purpose |
|--------|------|---------|
| log_id | INT | Unique log identifier |
| user_id | INT | Reference to users table |
| action | VARCHAR(50) | Action type (login_success, login_failure, etc.) |
| status | VARCHAR(20) | Status (success, failure, blocked, etc.) |
| ip_address | VARCHAR(45) | User's IP address (IPv4/IPv6) |
| details | JSON | Metadata (email, reason, etc.) |
| created_at | TIMESTAMP | When action occurred |

**Indexes (8 total):**
1. PRIMARY KEY (log_id)
2. idx_user_id - Find logs by user
3. idx_action - Find logs by action type
4. idx_status - Find logs by status
5. idx_created_at - Find logs by date
6. idx_ip_address - Find logs by IP
7. idx_user_created - Fast user+date queries
8. Foreign key index to users table

## 🚀 Deployment Checklist

### Pre-Deployment ✅
- [ ] Database backed up
- [ ] Code reviewed
- [ ] Test environment validated

### Deployment Steps ✅
- [ ] Run migration: `migrations/001_create_audit_logs_table.sql`
- [ ] Deploy code: Pull `feature/site-restructure` branch
- [ ] Clear caches

### Post-Deployment Testing ✅
- [ ] Test login (verify audit logs created)
- [ ] Test CSRF tokens on forms
- [ ] Test rate limiting (5+ attempts blocked)
- [ ] Test session regeneration
- [ ] Check error logs

### Success Criteria ✅
- [ ] audit_logs table created in database
- [ ] Login creates audit log entries
- [ ] Failed login creates log with failure reason
- [ ] CSRF tokens prevent form submission without token
- [ ] Rate limiting blocks after limit
- [ ] No error logs from new security classes
- [ ] Existing functionality works unchanged

## 🔄 Rollback Plan (If Needed)

### Option 1: Drop Audit Logs Table (Recommended)
```sql
DROP TABLE audit_logs;
```
- Impact: Audit logging stops, site continues
- Time: 1 minute
- Risk: None

### Option 2: Revert Code Only
```bash
git checkout <previous-commit-hash>
```
- Impact: Security features disabled
- Time: 5 minutes
- Risk: None

### Option 3: Full Rollback
- Restore database from backup
- Revert code to previous commit
- Time: 10-15 minutes
- Risk: None
