Comprehensive Security Hardening Checklist for Magento & Shopify

Introduction

Ecommerce platforms are lucrative targets for attackers. A systematic hardening process reduces attack surface, ensures PCI‑DSS compliance, and builds customer trust. This checklist consolidates best‑practice measures for both Magento and Shopify.

1. Infrastructure Hardening

2. Application‑Layer Hardening

2.1 Magento Specific

• Update to latest Magento version (include security patches).
  - Disable unused modules via bin/magento module:disable.
• Set file permissions: chmod 644 for files, chmod 750 for directories, chmod 770 for var, pub/media, pub/static.
• Admin URL Obfuscation – Change default /admin path to a random string.
• Two‑Factor Authentication (2FA) – Enable for all admin users.
• Content Security Policy (CSP) – Define allowed script/style sources.
• Secure XML and JSON API endpoints – Require authentication tokens.

2.2 Shopify Specific

• Use Shopify Payments (PCI‑validated) where possible.
• Enable two‑step verification for staff accounts.
• Restrict third‑party app permissions to least‑privilege.
• Audit API credentials regularly; rotate every 6 months.
• Enable Shopify’s built‑in fraud analysis.

3. Data Protection & Compliance

• Encrypt data at rest – Use LUKS for Magento databases; Shopify encrypts automatically.
• Tokenize payment data – Never store raw credit‑card numbers.
• Implement GDPR/CCPA consent banners and data‑deletion endpoints.
• Regular backups – Daily encrypted backups stored off‑site.

4. Monitoring & Incident Response

• Web Application Firewall (WAF) – Cloudflare Managed Rules (OWASP Top 10).
• Log aggregation – Ship Apache/Nginx, Magento, and Shopify logs to a SIEM (Elastic Stack).
• Alerting – Set thresholds for failed logins, unusual API traffic, and high error rates.
• Incident Playbook – Document steps: detection → containment → eradication → recovery → post‑mortem.

5. Penetration Testing & Vulnerability Scanning

6. Checklist Summary

• Use dedicated, patched server with firewall and SSH key auth.
• Enforce TLS 1.2+ and HSTS.
• Update Magento/Shopify to latest versions.
• Disable unused modules and set strict file permissions.
• Obfuscate admin URL and enable 2FA.
• Implement CSP and secure API authentication.
• Tokenize payment data; never store PAN.
• Encrypt data at rest and in transit.
• Set up WAF, log aggregation, and alerting.
• Conduct regular vulnerability scans and pen‑tests.
• Maintain up‑to‑date incident response plan.
