Magento Server Hardening Strategies to Prevent Exploits

1. Strengthening PHP: Critical php.ini Security

• PHP configuration requires careful attention for the store website security. Adjust the php.ini or use .user.ini system files.

• The disable_functions directive turns off specific PHP functions. The action reduces attacker toolkits after a successful exploitation.

• Common functions to disable include exec plus shell_exec. Test Magento functions after disabling these various PHP commands.

• The open_basedir directive restricts access to PHP script files. It defends against path traversal attack exploit type attempts.

• Set expose_php = Off to prevent PHP version disclosure. Attackers scan for specific PHP versions with known vulnerabilities.

2. Web Server (Nginx/Apache) Protection

• Your web server, like Nginx or Apache, is the frontline defense. Disabling any unneeded modules reduces the available attack surface.

• Confirm correct file permissions, plus the web server ownership. Web server users need minimal privileges on Magento directories.

• Prevent directory listing to stop showing directory file contents. Use Options -Indexes in Apache server configuration setting files.

• Enforce strong SSL/TLS configuration for site data encryption. Use TLS 1.2, TLS 1.3 with very strong cipher suites.

• Use security headers like CSP (Content-Security-Policy) for all protection. Restrict web access to sensitive server files.

3. Database Security Measures for Magento

• The Magento database contains very sensitive customer data. Network access controls restrict database connection type and host access.

• Configure MySQL bind-address = 127.0.0.1 for all local listening. Use firewalls like iptables for database port access control.

• Make sure that Magento database users have strong, unique passwords. The app/etc/env.php file stores these database user credentials.

• Database users need the lowest privileges for their database-related operations. Avoid granting the ALL PRIVILEGES command without a specific need.

• Use an automated, regular Magento database backup process. Keep MySQL software updated with security patches for good protection.

4. Granular File System Permissions for Least Privilege

• Prevent compromised web server processes from writing harmful files. One user owns files; a different user runs Magento.

• Deployment users own Magento files, plus all system directories. Web server users need limited write access for specific tasks.

• Directories var/, pub/media/, pub/static/ need web server write access. Other core Magento directories should remain set as read-only.

• Directory permissions are 750 or 755; files are 640. Use a restrictive umask like 0027 for new files.

• Verify file permissions against any unauthorized system user changes. It confirms ongoing Magento file system-level security.

5. Modern Containerization and Isolation Defenses

• Containerization, like Docker, adds significant security protection system layers. It isolates Magento plus its services from host systems.

• A compromise in one container limits other service impacts. It limits the exploit blast radius to container-specific resources.

• Treat containers as immutable for much better ongoing system security. Redeploy clean images to eradicate any harmful system modifications.

• Limit container CPU, memory, plus all network type resources. Confirm that base container images are from any trusted online sources.

• Use container runtime security monitoring for ongoing active protection. Be careful with volume mounts granting host path write access.
