How to Use Cloudflare to Protect Your Website

Cloudflare is a powerful platform that provides security, performance optimization, and reliability for websites. In this guide, we will cover how to use Cloudflare to protect your website and best security practices.

1. Setting Up Cloudflare for Your Website

Step 1: Sign Up and Add Your Website

1. Go to Cloudflare's website and sign up for an account.
2. Enter your domain name and click Add site.
3. Cloudflare will scan your DNS records automatically.

Step 2: Update Your Domain’s Nameservers

1. Cloudflare provides two nameservers.
2. Update your domain's nameservers at your domain registrar to point to Cloudflare’s nameservers.
3. Wait for the changes to propagate (can take a few hours).

Step 3: Configure Basic Security Settings

• Enable Always Use HTTPS under SSL/TLS settings.
• Set your SSL mode to Full (Strict) if you have a valid SSL certificate on your origin server.

2. Protecting Your Website with Cloudflare

A. Enable Web Application Firewall (WAF)

Cloudflare’s WAF helps block malicious traffic before it reaches your server.

• Go to Security > WAF and enable Managed Rules.
• Activate OWASP Core Rule Set to protect against common threats like SQL Injection and XSS.
• Add custom firewall rules to block specific threats.

B. Configure Rate Limiting

Rate limiting helps prevent brute-force attacks and DDoS attacks.

• Navigate to Security > Bots and enable Super Bot Fight Mode (for paid plans).
• Set up Rate Limiting Rules to block excessive requests from the same IP.

C. Enable DDoS Protection

Cloudflare automatically provides DDoS protection, but you can enhance it:

• Under Security > DDoS, ensure that DDoS protection is enabled.
• Use Under Attack Mode (via the Overview page) if your site is experiencing an active attack.

D. Secure Your API Endpoints

• Use API Shield (for Enterprise plans) to protect API traffic.
• Set Access Control Rules to restrict API access by IP or country.

3. Best Practices for Cloudflare Security

1. Minimize Direct Access to Your Origin Server

• Use Cloudflare Argo Tunnel (Cloudflare Tunnels) to keep your origin IP hidden.
• Restrict traffic to your server by allowing only Cloudflare IP ranges in your firewall.

2. Use Zero Trust Security for Admin Panels

• Enable Cloudflare Access to protect sensitive admin areas (e.g., /wp-admin, /admin).
• Require authentication (Google, GitHub, or SAML) for accessing restricted areas.

3. Enable Automatic HTTPS Rewrites

• Helps fix mixed content issues and ensures all resources load over HTTPS.

4. Monitor and Analyze Traffic

• Use Cloudflare Analytics to detect unusual traffic patterns.
• Check Firewall Events regularly for blocked threats.

5. Enable DNSSEC for Secure DNS Resolution

• Prevent DNS spoofing by enabling DNSSEC under Cloudflare’s DNS settings.
