What is the Web Application Firewall (WAF) in Cloudflare, and how do I configure it?

The WAF protects your website from common web vulnerabilities like SQL injection and cross-site scripting (XSS). Cloudflare offers managed rulesets and allows you to create custom rules. Access the 'WAF' section in the dashboard to configure rules, sensitivity levels, and action (block, challenge, log). Regularly review WAF logs to identify and address potential threats.
