Securing Your Magento 2 Store: Defending Against Search URL Spamming with a Custom Solution

Leave a Comment / Uncategorized / By /

As an e-commerce platform, Magento 2 offers robust features to create a seamless shopping experience for customers. However, one aspect that often requires attention is protecting the search URL from spamming. Unchecked spam can not only disrupt the search functionality but also hinder the overall performance of your Magento 2 store. In this article, we will explore the challenges posed by search URL spamming and discuss a custom solution to mitigate this issue effectively.

The Challenges of Search URL Spamming:

Search URL spamming occurs when malicious users or bots exploit the search functionality to flood the system with irrelevant or harmful queries. This can lead to various issues, including:

  1. Server Overload: The continuous influx of spam requests can cause server overload, leading to slow website performance or even crashes during peak traffic periods.
  2. Negative User Experience: When spam queries flood the search results, legitimate users may struggle to find relevant products or information, resulting in a poor user experience.
  3. Impact on SEO: Excessive spamming can negatively impact your website’s rankings, as search engines may perceive your site as providing poor quality or irrelevant content.
  4. Data Integrity: Spam queries can also affect the integrity of your data, making it challenging to extract meaningful insights or analyze customer behavior accurately.

To protect the Magento 2 search URL from spamming, I have developed a custom solution that combines several techniques to ensure a secure and efficient search experience. Here’s an overview of the solution:

Rate Limiting: Implementing rate limiting mechanisms allows you to control the number of requests a user or IP address can make within a specific timeframe. This helps prevent spamming by restricting the number of search queries from a single source.

Query Validation: Implement a robust query validation system to check the validity and relevance of search queries. By filtering out spam queries or those that do not meet certain criteria, you can ensure that only legitimate and meaningful searches are processed.

Please find the GitHub link for it: https://github.com/kushaljindal92/rate-limiting

Note: This works only for English websites, but you can update your regex as per your language.

Leave a Comment / Uncategorized / By /

Integrating Magento 2 with Cloudflare while hosting on AWS with a load balancer can provide enhanced performance, scalability, and security for your e-commerce website. Here’s an overview of the integration process:

  1. Set up Magento 2 on AWS:
    • Provision AWS infrastructure with EC2 instances for hosting Magento 2.
    • Configure an Amazon RDS database for storing website data.
    • Set up an Elastic Load Balancer (ELB) or an Application Load Balancer (ALB) to distribute traffic across multiple instances.
  2. Configure Cloudflare:
    • Sign up for a Cloudflare account and add your website.
    • Update your domain’s DNS settings to point to Cloudflare’s nameservers.
    • Enable Cloudflare’s CDN (Content Delivery Network) to cache and deliver static content globally.
  3. Configure Cloudflare Load Balancing:
    • Set up a Load Balancer in Cloudflare to distribute incoming traffic across your AWS instances.
    • Configure health checks to monitor the availability of your AWS instances.
    • Define load-balancing methods and rules based on your specific requirements.
  4. Enable Cloudflare Security Features:
    • Activate Cloudflare’s DDoS protection to safeguard your website against malicious attacks.
    • Enable Web Application Firewall (WAF) rules to protect against common web vulnerabilities.
    • Implement SSL/TLS encryption by enabling Cloudflare’s SSL/TLS feature or using your own SSL certificate.
  5. Optimize Performance:
    • Utilize Cloudflare’s performance features like Auto Minify to compress and optimize HTML, CSS, and JavaScript files.
    • Enable Brotli or Gzip compression to reduce file sizes and improve page load times.
    • Leverage Cloudflare’s Railgun technology for faster delivery of dynamic content.
  6. Fine-tune Cloudflare Settings:
    • Customize caching rules to ensure optimal caching of Magento 2 pages and resources.
    • Configure Page Rules to implement specific behaviors for different URLs or sections of your website.
    • Utilize Cloudflare Workers for advanced customization and logic implementation.
  7. Test and Monitor:
    • Thoroughly test your Magento 2 website after the integration to ensure proper functionality and performance.
    • Monitor website performance and security through Cloudflare analytics and monitoring tools.
    • Regularly review Cloudflare logs and reports to identify any potential issues or suspicious activity.

By integrating Magento 2 with Cloudflare while hosting on AWS with a load balancer, you can leverage the power of Cloudflare’s CDN, security features, and performance optimizations to deliver a fast, secure, and reliable e-commerce experience to your customers.

Magento 2 backup script for developer

Leave a Comment / Scripts / By / /

Magento 2 developer usually require taking backup of live environment and setup on local or creating staging environment. We need to take backup of Database, App folder and composer.json minimal. We can add media and other assets for full fledged setup. I created a simple script to create backup of these two folder after reading env.php file. It will decrease time to take backup. We just need to put these script at root and run it. It is very flexible and you can make changes to your requirement as well. I will keep updating it and will add new features.

<?php 
//create backup file
$envData = include('app/etc/env.php');

//taking database backup
echo "Taking database backup \n";
if(isset($envData['db'])){
    $mysqlDump = 'mysqldump --user='.$envData['db']['connection']['default']['username'].' --password='.$envData['db']['connection']['default']['password'].' --host='.$envData['db']['connection']['default']['host'] .' '.$envData['db']['connection']['default']['dbname'] .' > db.sql;'; 
    exec($mysqlDump);
}

//zipping files
echo "Zipping required files to setup environment \n";
exec('zip -r files.zip db.sql composer.json app/');

die('finished');
?>

Magento 2.x – Cannot process definition to array for type tinytext

Leave a Comment / Magento 2 bugs / By / /

I faced issue while setup:upgrade in magento 2 instance. I fixed this issue in three steps as below.

Step 1: I open this file : /vendor/magento/framework/Setup/Declaration/Schema/Db/DefinitionAggregator.php

Find this function and replace code:

   public function fromDefinition(array $data)
    {
        $type = $data['type'];
        if (!isset($this->definitionProcessors[$type])) {
            echo "<pre>"; print_r($data); exit();
            throw new \InvalidArgumentException(
                sprintf("Cannot process definition to array for type %s", $type)
            );
        }
        $definitionProcessor = $this->definitionProcessors[$type];
        return $definitionProcessor->fromDefinition($data);
    }

Step 2 : Run setup upgrade and you will find out column name and it’s details. Now login in to mysql console and replace invoiceNumber by column which we found in last step. You will get all table information.

SELECT table_name, column_name from information_schema.columns WHERE column_name LIKE '%invoiceNumber%';

Step 3: Now update that column using below command. Run again setup:upgrade

ALTER TABLE TableName MODIFY InvoiceNumber VARCHAR(250);

Font optimization to avoid invisible text

1 Comment / Magento 2 performace optimization / By / /

Every Magento 2 store needs fonts to display styled text. Like other static assets it use bandwidth. It affects performance, if do not download before text required it. I am adding few suggestions for font optimization and some resources links as well. I will keep updated information for font here

  1. Try to use google font (why? read this link)
  2. Use no more than two fonts and check their size as well.
  3. Load them on priority basis using preload and swap to avoid invisible text during font loading (check this link)
  4. Use proper caching for fonts (check this link)
  5. Use less variants of fonts
