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

# 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;
}

// 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';

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

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

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

// 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

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

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

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

• 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

• 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

// 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);
