Do more with AWS WAF labels using dynamic label interpolation
Brief
AWS WAF classifies web traffic by attaching metadata to each request it evaluates. Managed rule groups such as AWS WAF Bot Control and AWS WAF Fraud Control account takeover prevention (ATP) attach labels that describe what they found. A label can record that a request came from a known bot category or that it matched a credential-stuffing pattern.
You can forward that metadata to your origin as request headers, which gives your backend visibility into the decisions AWS WAF made at the edge. You can also use labels to build tiered policies: a low-confidence bot signal might trigger a CAPTCHA challenge, whereas a high-confidence signal blocks the request outright.
