🛡️ Security Best Practices

For Users

🔐 Authentication

// Always change default credentials
define('FM_USERNAME', 'your_secure_username');
define('FM_PASSWORD', 'YourVeryStrongPassword123!');

🌐 Access Control

# Restrict access by IP (Apache)
<Files "filemanager.php">
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
</Files>
# Restrict access by IP (Nginx)
location /filemanager.php {
    allow 192.168.1.0/24;
    allow 10.0.0.0/8;
    deny all;
}

🗄️ Database Security

// Use dedicated database user with minimal privileges
define('DB_USERNAME', 'filemanager_user');  // Not root!
define('DB_PASSWORD', 'SecureDBPassword123!');

// Grant only necessary privileges:
// GRANT SELECT, INSERT, UPDATE, DELETE ON app_db.* TO 'filemanager_user'@'localhost';

📂 File System Protection

// Set restrictive root path
define('FM_ROOT_PATH', '/var/www/secure_files');

// Never use system root
// define('FM_ROOT_PATH', '/');  // ❌ DANGEROUS!

For Administrators

🔒 HTTPS Only

  • Always use HTTPS in production
  • Implement HTTP to HTTPS redirects
  • Use strong SSL/TLS certificates

🕒 Session Security

// Configure secure session settings
ini_set('session.cookie_secure', 1);      // HTTPS only
ini_set('session.cookie_httponly', 1);    // No JavaScript access
ini_set('session.use_strict_mode', 1);    // Strict session handling

📝 Logging and Monitoring

  • Enable PHP error logging
  • Monitor file access patterns
  • Set up intrusion detection
  • Regular security audits

🔄 Regular Updates

  • Keep PHP updated
  • Update web server software
  • Monitor for security advisories
  • Apply patches promptly

🚫 Known Security Considerations

⚠️ Current Limitations

  1. Single User System: Currently supports only one admin user
  2. File Type Restrictions: Limited to predefined safe file types
  3. No Rate Limiting: No built-in protection against brute force
  4. Session Storage: Uses default PHP session storage

🔧 Planned Security Enhancements

  • Multi-user support with role-based access
  • Two-factor authentication (2FA)
  • Rate limiting for login attempts
  • File integrity checking
  • Audit logging
  • API key authentication option

🔍 Security Features

✅ Current Protections

  • CSRF Protection: All forms use CSRF tokens
  • Path Sanitization: Prevents directory traversal attacks
  • Session Management: Secure session handling with timeouts
  • Input Validation: All user inputs are validated and sanitized
  • SQL Injection Protection: PDO with prepared statements
  • File Type Restrictions: Only safe file types for editing
  • Authentication Required: All operations require valid login

🛠️ Built-in Security Functions

// Path sanitization
function sanitizePath($path);

// CSRF token management
function generateCSRFToken();
function validateCSRFToken($token);

// Authentication checks
function isAuthenticated();
function updateLastActivity();

// Real path validation
function getRealPath($path);
