Making sure that your security patches are up to date is a Magento security best practice. You can update them by downloading and applying the patch to your Magento store, which is essential as these critical patches will help protect your ecommerce setup from security flaws and cyberthreats.

Level 1 Payment Card Industry (PCI) compliance

Magento solutions are Level 1 PCI compliant solutions so that your customers know your ecommerce platform is safe, secured, and follows industry standards for both processing and transmission of cardholders' data. A key part of PCI compliance is ModSecurity (ModSec). This Apache module protects your ecommerce from external attacks. It detects and blocks intrusions, making it a fundamental Magento best security practice.

ModSecurity (ModSec)

ModSecurity is one of the core components for Magento 2 security as it helps prevent:

  • Brute force attacks (designed to guess usernames and passwords quickly until gaining access)
  • SQL injections (designed to access sensitive information by entering SQL in URL fields, login forms, etc.)
  • Inclusion vulnerabilities (designed to maneuver through applications with insecure code using the attackers' code)
  • Other types of attacks.

One of the many ModSec functions is real-time security control, continuous passive security assessment, and web application hardening.

Progressive Web Applications (PWAs)

For additional Magento 2 security, Magento solutions have a PWA-readiness to enhance security. Progressive Web Applications (PWAs) are a web technology that provides lightning-fast page loading, a flexible customer user interface, offline purchases, no marketplace submissions, and overall better flexibility within the ecommerce management system.
