🔒 Support for Content Security Policy (CSP)
🔐 HTTP Strict Transport Security (HSTS)
🚫 X-Frame-Options protection
🔍 X-Content-Type-Options
🛑 X-XSS-Protection
📝 Referrer Policy
🎯 Permissions Policy
📱 Client Hints Policy
⚙️ Two security levels: Basic and Strict
🔄 Automatic nonce generation for CSP
⚡ Framework integrations (Laravel & Symfony)

Installation

You can install the package via composer:

composer require easyshield/php-secure-headers

Quick Usage

Method 1: Plain PHP

Just 5 lines of code to enable all security headers:

<?php
// Create the headers instance
$headers = new \EasyShield\SecureHeaders\SecureHeaders();
$headers->enableAllSecurityHeaders();

// Apply headers
foreach ($headers->getHeaders() as $name => $value) {
    header("$name: $value");
}

Method 2: Laravel Integration

In Laravel, just add the middleware:

<?php
// app/Http/Middleware/SecureHeadersMiddleware.php
namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use EasyShield\SecureHeaders\SecureHeaders;
use Symfony\Component\HttpFoundation\Response;

class SecureHeadersMiddleware
{
    private SecureHeaders $headers;
    
    public function __construct()
    {
        $this->headers = new SecureHeaders();
        $this->headers->enableAllSecurityHeaders();
    }
    
    public function handle(Request $request, Closure $next): Response
    {
        $response = $next($request);
        
        foreach ($this->headers->getHeaders() as $name => $value) {
            $response->headers->set($name, $value);
        }
        
        return $response;
    }
}

Then register it in bootstrap/app.php:

->withMiddleware(function (Middleware $middleware) {
    $middleware->append(\App\Http\Middleware\SecureHeadersMiddleware::class);
})

Method 3: Symfony Integration

<?php
// src/EventSubscriber/SecureHeadersSubscriber.php
namespace App\EventSubscriber;

use EasyShield\SecureHeaders\SecureHeaders;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\ResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;

class SecureHeadersSubscriber implements EventSubscriberInterface
{
    private SecureHeaders $headers;
    
    public function __construct()
    {
        $this->headers = new SecureHeaders();
        $this->headers->enableAllSecurityHeaders();
    }
    
    public static function getSubscribedEvents(): array
    {
        return [
            KernelEvents::RESPONSE => 'onKernelResponse',
        ];
    }
    
    public function onKernelResponse(ResponseEvent $event): void
    {
        if (!$event->isMainRequest()) {
            return;
        }
        
        $response = $event->getResponse();
        
        foreach ($this->headers->getHeaders() as $name => $value) {
            $response->headers->set($name, $value);
        }
    }
}

Custom Configuration

Enable only specific headers:

$headers = new \EasyShield\SecureHeaders\SecureHeaders();

// Enable only specific headers
$headers->enableHSTS()
        ->enableXFrameOptions()
        ->enableXContentTypeOptions();

Custom CSP

Method 1: Using Array Configuration

$headers->enableCSP([
    'default-src' => ["'self'"],
    'script-src' => ["'self'", "https://trusted.com"],
    'style-src' => ["'self'", "'unsafe-inline'"],
    'img-src' => ["'self'", "data:", "https:"],
    'font-src' => ["'self'", "https://fonts.gstatic.com"],
    'connect-src' => ["'self'", "https://api.example.com"]
]);

Method 2: Using CSP Builder (Fluent API)

// Get CSP builder instance and configure it
$headers->csp()
    ->allowScripts('https://trusted.com')
    ->allowStyles('https://fonts.googleapis.com')
    ->allowImages('https://images.example.com', 'data:')
    ->allowFonts('https://fonts.gstatic.com')
    ->allowConnections('https://api.example.com')
    ->blockFrames()
    ->useStrictDynamic()
    ->upgradeInsecureRequests();

// Apply the CSP configuration
$headers->enableCSP();

Advanced CSP Features

Auto-detecting external resources from HTML:

// Analyze HTML and automatically add sources to CSP
$html = '<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>';
$headers->csp()->detectExternalResourcesFromHtml($html);
$headers->enableCSP();

Auto-injecting nonces into HTML:

// Inject nonces into script and style tags
$html = '<script>console.log("Hello");</script>';
$modifiedHtml = $headers->csp()->injectNoncesToHtml($html);
$headers->enableCSP();

// Output: <script nonce="random-nonce-value">console.log("Hello");</script>

Using hashes for inline scripts instead of nonces:

$headers->csp()
    ->addScriptHash('sha256', 'HashOfYourInlineScript')
    ->addStyleHash('sha256', 'HashOfYourInlineStyle');
$headers->enableCSP();

Custom HSTS

$headers->enableHSTS(
    maxAge: 31536000, // 1 year
    includeSubDomains: true,
    preload: true
);

Custom Permissions Policy

$headers->enablePermissionsPolicy([
    'camera' => ["'self'"],
    'microphone' => ["'none'"],
    'geolocation' => ["'self'", "https://maps.example.com"]
]);

هدرهای امنیتی PHP

یک کتابخانه قدرتمند PHP برای مدیریت هدرهای امنیتی در برنامه‌های وب. این کتابخانه با پیکربندی آسان انواع هدرهای امنیتی از جمله Content Security Policy (CSP)، HTTP Strict Transport Security (HSTS) و موارد دیگر، به شما کمک می‌کند بهترین روش‌های امنیتی را پیاده‌سازی کنید.

ویژگی‌ها

🛡️ پیکربندی آسان هدرهای امنیتی
🔒 پشتیبانی از سیاست امنیتی محتوا (CSP)
🔐 امنیت انتقال سختگیرانه HTTP (HSTS)
🚫 محافظت X-Frame-Options
🔍 X-Content-Type-Options
🛑 X-XSS-Protection
📝 سیاست ارجاع (Referrer Policy)
🎯 سیاست مجوزها (Permissions Policy)
📱 سیاست اطلاعات مشتری (Client Hints Policy)
⚙️ دو سطح امنیتی: پایه و سختگیرانه
🔄 تولید خودکار nonce برای CSP
⚡ ادغام با فریم‌ورک‌ها (Laravel و Symfony)

نصب

می‌توانید این پکیج را از طریق Composer نصب کنید:

composer require easyshield/php-secure-headers

استفاده سریع

روش 1: PHP ساده

تنها با 5 خط کد، تمام هدرهای امنیتی را فعال کنید:

<?php
// ایجاد نمونه هدر
$headers = new \EasyShield\SecureHeaders\SecureHeaders();
$headers->enableAllSecurityHeaders();

// اعمال هدرها
foreach ($headers->getHeaders() as $name => $value) {
    header("$name: $value");
}

روش 2: ادغام با Laravel

در Laravel، کافی است میدلور را اضافه کنید:

<?php
// app/Http/Middleware/SecureHeadersMiddleware.php
namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use EasyShield\SecureHeaders\SecureHeaders;
use Symfony\Component\HttpFoundation\Response;

class SecureHeadersMiddleware
{
    private SecureHeaders $headers;
    
    public function __construct()
    {
        $this->headers = new SecureHeaders();
        $this->headers->enableAllSecurityHeaders();
    }
    
    public function handle(Request $request, Closure $next): Response
    {
        $response = $next($request);
        
        foreach ($this->headers->getHeaders() as $name => $value) {
            $response->headers->set($name, $value);
        }
        
        return $response;
    }
}

سپس آن را در bootstrap/app.php ثبت کنید:

->withMiddleware(function (Middleware $middleware) {
    $middleware->append(\App\Http\Middleware\SecureHeadersMiddleware::class);
})

روش 3: ادغام با Symfony

<?php
// src/EventSubscriber/SecureHeadersSubscriber.php
namespace App\EventSubscriber;

use EasyShield\SecureHeaders\SecureHeaders;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\ResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;

class SecureHeadersSubscriber implements EventSubscriberInterface
{
    private SecureHeaders $headers;
    
    public function __construct()
    {
        $this->headers = new SecureHeaders();
        $this->headers->enableAllSecurityHeaders();
    }
    
    public static function getSubscribedEvents(): array
    {
        return [
            KernelEvents::RESPONSE => 'onKernelResponse',
        ];
    }
    
    public function onKernelResponse(ResponseEvent $event): void
    {
        if (!$event->isMainRequest()) {
            return;
        }
        
        $response = $event->getResponse();
        
        foreach ($this->headers->getHeaders() as $name => $value) {
            $response->headers->set($name, $value);
        }
    }
}

پیکربندی سفارشی

فعال‌سازی فقط هدرهای خاص:

$headers = new \EasyShield\SecureHeaders\SecureHeaders();

// فعال‌سازی فقط هدرهای خاص
$headers->enableHSTS()
        ->enableXFrameOptions()
        ->enableXContentTypeOptions();

CSP سفارشی

روش 1: استفاده از پیکربندی آرایه‌ای

$headers->enableCSP([
    'default-src' => ["'self'"],
    'script-src' => ["'self'", "https://trusted.com"],
    'style-src' => ["'self'", "'unsafe-inline'"],
    'img-src' => ["'self'", "data:", "https:"],
    'font-src' => ["'self'", "https://fonts.gstatic.com"],
    'connect-src' => ["'self'", "https://api.example.com"]
]);

روش 2: استفاده از CSP Builder (API روان)

// دریافت نمونه CSP builder و پیکربندی آن
$headers->csp()
    ->allowScripts('https://trusted.com')
    ->allowStyles('https://fonts.googleapis.com')
    ->allowImages('https://images.example.com', 'data:')
    ->allowFonts('https://fonts.gstatic.com')
    ->allowConnections('https://api.example.com')
    ->blockFrames()
    ->useStrictDynamic()
    ->upgradeInsecureRequests();

// اعمال پیکربندی CSP
$headers->enableCSP();

ویژگی‌های پیشرفته CSP

تشخیص خودکار منابع خارجی از HTML:

// تحلیل HTML و افزودن خودکار منابع به CSP
$html = '<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>';
$headers->csp()->detectExternalResourcesFromHtml($html);
$headers->enableCSP();

تزریق خودکار nonce به HTML:

// تزریق nonce به تگ‌های script و style
$html = '<script>console.log("Hello");</script>';
$modifiedHtml = $headers->csp()->injectNoncesToHtml($html);
$headers->enableCSP();

// خروجی: <script nonce="مقدار-تصادفی-nonce">console.log("Hello");</script>

استفاده از hash برای اسکریپت‌های درون‌خطی به جای nonce:

$headers->csp()
    ->addScriptHash('sha256', 'HashOfYourInlineScript')
    ->addStyleHash('sha256', 'HashOfYourInlineStyle');
$headers->enableCSP();

HSTS سفارشی

$headers->enableHSTS(
    maxAge: 31536000, // 1 year
    includeSubDomains: true,
    preload: true
);

Custom Permissions Policy

$headers->enablePermissionsPolicy([
    'camera' => ["'self'"],
    'microphone' => ["'none'"],
    'geolocation' => ["'self'", "https://maps.example.com"]
]);
