Ways to Enhance Magento 2 Store Security: A Comprehensive Guide by Kiwi Commerce

Magento 2 provides a robust foundation for creating secure online stores, but maintaining strong security requires an ongoing, proactive approach. With the ever-evolving landscape of cyber threats, it’s essential to adopt the right security measures to safeguard your online business. In this blog, Kiwi Commerce explores some effective strategies to enhance the security of your Magento 2 store and ensure your customers’ data remains protected.

1. Keep Magento and Extensions Updated

One of the most crucial aspects of Magento 2 security is keeping both the platform and all installed extensions up to date. Security patches are released regularly to address newly discovered vulnerabilities, and outdated software becomes an easy target for cyber attackers. To maintain security, schedule regular updates, test them in a staging environment, and deploy them as soon as they are confirmed to be stable.

Why It Matters:
By updating Magento and extensions promptly, you reduce the risk of known security flaws being exploited. Regular updates help ensure that your store remains protected from emerging threats.

2. Enable Two-Factor Authentication (2FA)

Magento 2 supports Two-Factor Authentication (2FA) out of the box, which adds an extra layer of security to your admin accounts. With 2FA enabled, even if an attacker obtains your password, they won’t be able to access your account without the second authentication step, which typically involves a mobile app or email.

Why It Matters:
2FA significantly enhances the security of your store by requiring more than just a password to gain access, making it much harder for attackers to infiltrate your system.

3. Use a Unique Admin URL

Default admin URLs like /admin are easy targets for attackers who scan websites for common login pages. By changing your admin URL to something unique, you make it significantly harder for automated attacks or brute-force login attempts to succeed.

Why It Matters:
A unique admin URL adds a layer of obscurity to your store’s backend, reducing the chances of cyber attackers targeting your login page.

4. Implement a Web Application Firewall (WAF)

A Web Application Firewall (WAF) serves as your first line of defence against malicious traffic. A WAF can filter out harmful requests before they reach your Magento store, blocking threats such as SQL injection, cross-site scripting (XSS), and other common attacks. Popular WAF services like Cloudflare or Sucuri can be easily integrated with Magento.

Why It Matters:
By implementing a WAF, you proactively block malicious traffic and reduce the likelihood of attacks affecting your store. It’s an essential security tool for protecting your website from a range of threats.

5. Enforce HTTPS for All Connections

Installing an SSL certificate ensures that all data exchanged between your Magento store and users is encrypted. HTTPS not only helps protect sensitive customer information but also serves as a trust signal, reassuring your visitors that their data is secure. Additionally, HTTPS is a ranking factor for search engines, which can benefit your store’s visibility.

Why It Matters:
Secure connections via HTTPS are essential for customer trust and SEO performance. Without HTTPS, your store is vulnerable to data breaches, and you could lose potential customers.

6. Strengthen Server Security

Securing your hosting server is just as important as securing your Magento 2 store. To protect against intrusions, restrict access to critical files (such as env.php), close unused ports, and configure tools like fail2ban to block suspicious IP addresses. You may also want to consider using a dedicated or cloud hosting provider that offers enhanced security options.

Why It Matters:
Securing your server ensures that attackers can’t gain access to critical files or use your server as a point of entry to compromise your store.

7. Use Strong Admin and User Credentials

Weak passwords continue to be a common cause of data breaches. Enforce strong, unique passwords for all admin accounts and user logins, combining uppercase and lowercase letters, numbers, and special characters. Additionally, conduct regular audits of user roles and permissions, removing inactive or unnecessary accounts to minimise potential attack vectors.

Why It Matters:
Strong passwords and proper access control reduce the risk of unauthorised access, making it more difficult for attackers to breach your Magento 2 store.

8. Set Correct File and Directory Permissions

Incorrect file and directory permissions can expose sensitive files to unauthorised users. Ensure that file permissions are set securely, such as 644 for files and 755 for directories. Avoid using overly permissive settings like 777, as this allows anyone to modify files.

Why It Matters:
By properly configuring file and directory permissions, you ensure that only authorised users and processes have access to critical files, preventing unauthorised modifications.

9. Monitor and Review Activity Logs

Magento 2 includes a powerful logging feature that tracks admin activities and system events. By reviewing activity logs regularly, you can spot unusual actions such as multiple failed login attempts, unauthorised file changes, or spikes in resource usage.

Why It Matters:
Regularly monitoring activity logs helps you detect abnormal behaviour before it turns into a serious issue. Proactive log monitoring is essential for identifying potential security breaches early.

10. Defend Against Brute-Force Attacks

Brute-force attacks involve hackers repeatedly attempting to guess login credentials by trying various combinations. To protect against this, limit the number of failed login attempts, enable CAPTCHA on all admin login pages, and implement CAPTCHA on customer account creation forms.

Why It Matters:
Brute-force attacks are one of the most common ways cybercriminals attempt to gain access to accounts. Limiting failed attempts and using CAPTCHA makes it much more difficult for attackers to succeed.
