Essential Tools Checklist

行動： 在免費的Cloudflare帳戶中添加您的網域，並將您網域的名稱伺服器指向Cloudflare。
Layer 1: Cloudflare (Network Protection)Purpose: This is your site’s frontline defense. It acts as a reverse proxy to protect against Distributed Denial of Service (DDoS) attacks and functions as a Content Delivery Network (CDN) to speed up global load times. Protection is automatic once setup is complete.
Action: Add your domain to a free Cloudflare account and change your domain’s nameservers to point to Cloudflare.

行動： 從WordPress外掛目錄安裝並啟用。設定防火牆並定期執行惡意軟體掃描。
Layer 2: Wordfence Security (Core Security Plugin)Purpose: An all-in-one security plugin for WordPress itself. Its Web Application Firewall (WAF) blocks malicious traffic, it scans for malware, and protects your login page from brute-force attacks.
