阿里云Web应用防火墙

Alibaba Cloud Web Application Firewall (WAF) is a security service designed to protect web applications from malicious traffic and cyber threats. It acts as a protective barrier between the internet and the application servers, inspecting incoming HTTP and HTTPS requests before they reach the backend infrastructure. The system is utilized by administrators to secure websites, APIs, and web services against a wide array of attack vectors. One of the primary functions of this firewall is the detection and mitigation of common web vulnerabilities. It monitors traffic for exploits targeting weaknesses outlined in the OWASP Top Ten, such as SQL injection, cross-site scripting (XSS), file inclusion, and remote code execution. By utilizing predefined rule sets, the system identifies malicious payloads within the request headers, body, and parameters, blocking the attack and preventing unauthorized access to the database or server files.

Automated scripts and crawlers often consume excessive server bandwidth, scrape sensitive content, or attempt credential stuffing. The firewall analyzes client behavior, browser fingerprints, and request
