Cloudflare Application Security study guide
Cloudflare Application Security · Work through your exam, one topic at a time.
The Cloudflare Application Security certification is an independent study credential for security engineers, SOC analysts, DevOps practitioners, and web platform owners who need to defend internet-facing applications. It is not affiliated with, endorsed by, or sponsored by Cloudflare, Inc.; this page is an independent preparation guide. The exam is organized into four equally weighted domains: Web Security Fundamentals, DDoS Mitigation, Web Application Firewall (WAF), and Bot Management. Questions test practical judgment about how requests are inspected, how attacks are classified, how mitigation rules are ordered and tuned, and how to reduce false positives without weakening protection. The Cloudflare Application Security study guide has 4 sections and about 1,794 words.
01Web Security Fundamentals
Web Security Fundamentals covers the plumbing the rest of the exam assumes: how HTTP requests traverse Cloudflare's reverse proxy, how TLS is terminated and re-established to the origin, and which protections are enforced by browsers rather than by the edge. Questions here test whether you can predict the effect of a configuration change before you make it.
472 words, about 2 min02DDoS Mitigation
DDoS Mitigation tests whether you know which attack types Cloudflare absorbs automatically, which need configuration, and how those controls interact with caching and legitimate traffic. Network-layer attacks - SYN floods, UDP amplification, DNS reflection, GRE floods - are handled by Cloudflare's edge automatically and are unmetered on every plan.
454 words, about 2 min03Web Application Firewall (WAF)
The WAF domain tests rule authoring and rule ordering: given a request and a rule set, can you say exactly what happens? Cloudflare's WAF combines managed rulesets, custom rules, and rate limiting rules that evaluate in a defined order.
416 words, about 2 min04Bot Management
Bot Management tests your ability to separate good automation from bad, and to enforce without collateral damage to search crawlers, monitoring, and payment providers. Every request receives a bot score from 1 to 99 : 1 is definitely automated, 99 is definitely human.
