Real-time monitoring of PHP security vulnerabilities

Method to monitor PHP security vulnerabilities in real time: Install the Sentry library and configure Sentry DSN to capture errors and exceptions, and record security vulnerability tags. Create Sentry alerts, identify and record security vulnerabilities based on the trigger of security vulnerability tags, and take protective measures in a timely manner

Real-time monitoring of PHP security vulnerabilities

Introduction

PHP is a popular Web development language, but it is also subject to security vulnerabilities. Real-time monitoring of these vulnerabilities is critical to protecting web applications from attacks. This article will guide you on how to use Sentry to monitor PHP security vulnerabilities in real time.

Prerequisites

##PHP >= 7.1
• Sentry Account
• Running PHP Web Application

Install Sentry

composer require sentry/sentry

Configure Sentry

In the application’s

.env file or ## Configure Sentry in #config/app.php: <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>// .env SENTRY_DSN=&quot;https://YOUR_DSN_HERE@sentry.io/YOUR_PROJECT_ID&quot; // config/app.php 'providers' =&gt; [ // ... Sentry\Laravel\ServiceProvider::class, ],</pre><div class="contentsignin">Copy after login</div></div>

Logging errors and exceptions

Use SentryFacades to log errors and exceptions:

use Sentry\Severity;

try {
    // ...
} catch (\Exception $e) {
    Sentry::captureException($e, [
        'level' => Severity::error(),
    ]);
}

Monitor security vulnerabilities

You can monitor security vulnerabilities by creating alerts in the Sentry dashboard:

Navigate to the "Alerts" tab.

• Click the "Create New Alert" button.
• Select "Grouped Over Time" as "Alert Type".
• Select "Events with Specific Properties" under "Triggered By".
• Enter "tags.security_vulnerability" in the "Property" field.
• Select "Exists" in the "Operator" field.
• Set the alert's severity level and other options.

Practical case

Consider a security vulnerability in the following code:

<?php
if (isset($_GET['id'])) {
    $userId = $_GET['id'];
    // ...
}

This code is vulnerable to SQL injection attacks because there is no Validate the

$userId

input. Use Sentry to log the vulnerability:

if (!is_int($userId)) {
    Sentry::captureException(new \Exception('Invalid user ID'), [
        'level' => Severity::warning(),
        'tags' => [
            'security_vulnerability' => true,
        ],
    ]);
}

In this way, we can monitor this security vulnerability in real time and take appropriate measures to protect the application.
