Security Analysis

Security Issues Checklist

Critical Priority

  • 1. Implement Password Security

    • Add password hashing using PASSWORD_BCRYPT

    • Complete password reset functionality
    • Add password change verification

  • 2. Add CSRF Protection

    • Implement CSRF token generation
    • Add CSRF validation to all forms

    • Add rate limiting for login attempts

High Priority

  • 4. Strengthen XSS Protection

    • Implement output escaping across all views
    • Add Content Security Policy headers
    • Enable X-XSS-Protection header
    • Sanitize all user inputs

  • 5. Ensure SQL Injection Protection

    • Audit all queries for prepared statements
    • Implement consistent input sanitization
    • Add query logging for suspicious patterns

  • 6. Implement Account Security

    • Add account lockout after failed attempts
    • Implement progressive delays between attempts
    • Add suspicious activity notifications
    • Implement two-factor authentication

Medium Priority

  • 7. Add Security Headers

    • Strict-Transport-Security
    • X-Frame-Options
    • X-Content-Type-Options
    • Referrer-Policy

  • 8. Implement Comprehensive Logging

    • Log authentication attempts
    • Log password reset requests
    • Log suspicious activities
    • Set up log rotation and monitoring

  • 9. API Security Enhancements

    • Implement API rate limiting
    • Add JWT authentication
    • Add input validation for all endpoints
    • Implement proper error handling

Maintenance Tasks

  • 10. Regular Security Maintenance
    • Update all dependencies
    • Review security measures
    • Implement security monitoring
    • Conduct security audits
    • Update security documentation
    • Schedule developer security training

Current Security Measures

Session Management

✅ Positive Implementations:

  • HTTPOnly flag is enabled for session cookies
  • Forces sessions to only use cookies
  • Session cookies expire when browser closes
  • Secure flag enabled in production environments
  • Domain restricted to current domain only
  • JavaScript access to session cookies is prevented

Database Security

✅ Positive Implementations:

  • Uses PDO with prepared statements
  • Explicit error mode settings
  • Database credentials stored in environment variables
  • Character set explicitly set to utf8mb4
  • Emulated prepares disabled
  • Exception handling for database connections

Authentication Flow

✅ Positive Implementations:

  • Input validation before authentication
  • Session regeneration on login
  • Proper session cleanup on logout
  • Checks for existing sessions
  • Email/password combination validation
  • Username and email uniqueness verification
  • AJAX responses for error handling

Implementation Details

Password Security Implementation

// Use password_hash with strong algorithm
$hash = password_hash($password, PASSWORD_BCRYPT, ['cost' => 12]);

// Implement password complexity validation
function validate_password_strength($password) {
    if (strlen($password) < 12) return false;
    if (!preg_match("/[A-Z]/", $password)) return false;
    if (!preg_match("/[a-z]/", $password)) return false;
    if (!preg_match("/[0-9]/", $password)) return false;
    if (!preg_match("/[^A-Za-z0-9]/", $password)) return false;
    return true;
}

CSRF Protection Implementation

// Generate CSRF token
function generate_csrf_token() {
    if (empty($_SESSION['csrf_token'])) {
        $_SESSION['csrf_token'] = bin2hex(random_bytes(32));
    }
    return $_SESSION['csrf_token'];
}

// Validate CSRF token
if (!hash_equals($_SESSION['csrf_token'], $_POST['csrf_token'])) {
    die('CSRF token validation failed');
}

Session Security Implementation

// Add session timeout
ini_set('session.gc_maxlifetime', 1800); // 30 minutes
session_set_cookie_params(1800);

// Add session fixation protection
session_regenerate_id(true);

// Add IP binding
$_SESSION['ip'] = $_SERVER['REMOTE_ADDR'];
$_SESSION['user_agent'] = $_SERVER['HTTP_USER_AGENT'];

SQL Protection Implementation

// Always use prepared statements
$stmt = $pdo->prepare("SELECT * FROM users WHERE email = ?");
$stmt->execute([$email]);

// Implement input sanitization
function sanitize_input($data) {
    return htmlspecialchars(strip_tags(trim($data)));
}

XSS Protection Implementation

// Input sanitization function
function sanitize_input($data) {
    if (is_array($data)) {
        return array_map('sanitize_input', $data);
    }
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data, ENT_QUOTES | ENT_HTML5, 'UTF-8');
    return $data;
}

// Output escaping function
function escape_output($output) {
    return htmlspecialchars($output, ENT_QUOTES | ENT_HTML5, 'UTF-8');
}

// Initialize secure session with proper cookie settings
function init_secure_session() {
    if (session_status() === PHP_SESSION_NONE) {
        $secure = true;
        $httponly = true;
        $samesite = 'Strict';
        
        session_set_cookie_params([
            'lifetime' => SESSION_LIFETIME,
            'path' => '/',
            'domain' => $_SERVER['HTTP_HOST'],
            'secure' => $secure,
            'httponly' => $httponly,
            'samesite' => $samesite
        ]);
        
        session_start();
    }
}

// Set comprehensive security headers
function set_security_headers() {
    if (!headers_sent()) {
        // Content Security Policy
        $csp = [
            "default-src 'self'",
            "script-src 'self' 'unsafe-inline'",
            "style-src 'self' 'unsafe-inline'",
            "img-src 'self' data:",
            "font-src 'self'",
            "frame-ancestors 'self'",
            "form-action 'self'",
            "base-uri 'self'",
            "object-src 'none'"
        ];
        header("Content-Security-Policy: " . implode("; ", $csp));
        
        // Additional security headers
        header("X-Content-Type-Options: nosniff");
        header("X-Frame-Options: SAMEORIGIN");
        header("X-XSS-Protection: 1; mode=block");
        header("Referrer-Policy: strict-origin-when-cross-origin");
        header("Strict-Transport-Security: max-age=31536000; includeSubDomains");
    }
}
