SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires requests.

What problem does it solve?

Web applications and APIs face volumetric, protocol, and application-layer DDoS attacks that can take services offline. This Skill guides you through configuring Cloudflare's multi-layer DDoS protection stack so attacks are detected and mitigated at the edge before reaching your origin.

Core Features & Use Cases

  • Managed Ruleset Configuration: Override HTTP and network-layer DDoS managed rulesets with tuned sensitivity levels and block actions via the Cloudflare API.
  • Rate Limiting & WAF Rules: Create rate limiting rules for login and API endpoints, plus custom WAF rules for ASN, geography, and request-size filtering.
  • Origin Protection & Automation: Lock the origin firewall to Cloudflare IP ranges, enable Authenticated Origin Pulls, and automate Under Attack Mode with a Python traffic-monitoring script.
  • Use Case: Your login endpoint is being hit by a credential-stuffing flood. Use this Skill to deploy a rate limiting rule keyed on source IP, verify blocked events in Firewall analytics, and confirm the origin refuses direct non-Cloudflare connections.

Quick Start

Ask the AI to configure Cloudflare DDoS protection for your domain, including rate limiting on the login endpoint and origin IP lockdown.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure Cloudflare DDoS protection for my website?▼

Onboard your domain to Cloudflare with proxied DNS records, then override the HTTP and network-layer DDoS managed rulesets via the rulesets API with appropriate sensitivity levels and block actions. Layer rate limiting, WAF custom rules, and origin firewall restrictions on top.

How to set up Cloudflare rate limiting for a login endpoint?▼

Create a rule in the http_ratelimit phase matching the login path with a requests-per-period threshold keyed on ip.src, using a block or managed_challenge action. Size the threshold against real peak traffic so distributed floods are actually caught.

Does Cloudflare DDoS protection work if my origin IP is exposed?▼

No. If attackers know your origin IP, they can bypass Cloudflare entirely and attack the server directly. Restrict the origin firewall to Cloudflare IP ranges only and enable Authenticated Origin Pulls with mutual TLS.

Why is my Cloudflare DDoS rule not blocking attacks?▼

The rule is likely left in log mode or set to sensitivity essentially_off, which detects but never blocks. Verify the deployed action is block or managed_challenge via the rulesets API, and confirm blocked events appear in Firewall analytics during a test.

What Cloudflare plan do I need for DDoS protection?▼

Basic L3/L4 DDoS protection is included on all plans, but WAF custom rules require at least the Pro plan, and Advanced DDoS features like Advanced TCP Protection require Enterprise. Bot Management is also an Enterprise-tier feature.
