Top Magento Security Best Practices for Store Owners & Developers

I’m in Biz Dev with a firm (Alexandra Tech Lab) that performs budget-friendly custom software development leveraging Magento. Here are some Security tips and tricks I’ve picked up from our development team:​

• Keep Magento & Extensions Updated
Patch vulnerabilities fast by using the latest versions.
• Use Strong Passwords + 2FA
Enforce strong credentials and enable two-factor authentication for all admin users.
• Change the Default Admin URL
Obscure your backend to reduce automated attacks.
• Enable HTTPS Everywhere
Use SSL across the site, especially for admin and checkout areas.
• Set Correct File Permissions
Apply least-privilege access (644 for files, 755 for directories), avoid 777.
• Use a Web Application Firewall (WAF)
Protect against common attacks like XSS, SQL injection, and bots.
• Install Only Trusted Extensions
Vet third-party code for quality and security—less is more.
• Restrict Admin Access by IP or VPN
Limit who can reach your admin panel.
• Monitor Logs & Enable Magento Security Scan
Watch for suspicious activity and scan regularly for vulnerabilities.
• Automate Offsite Backups
Secure, regular backups are your safety net—don’t go without them.
