To summarize the key steps to boost Magento store security: 1. Keep the Magento software and all plugins updated to the latest versions to patch vulnerabilities. 2. Backup the website data regularly and store the backups on a separate server to ensure the data can be restored in the event of a server crash or hacker access. 3. Use strong, unique passwords and enable two-factor authentication for admin logins to improve login security. Also use a firewall, monitor logs for suspicious activity, and change the backend URL to enhance protection.
