Which service offers firewall-related functionalities on Alibaba Cloud?

The Alibaba Cloud Web Application Firewall (WAF) specifically offers firewall-related functionalities that protect web applications from various threats and vulnerabilities. WAF is designed to safeguard websites from common web attacks such as SQL injection, cross-site scripting (XSS), and distributed denial-of-service (DDoS) attacks. It operates by filtering and monitoring HTTP/HTTPS traffic between users and web applications, allowing for proactive measures to block malicious traffic while allowing legitimate requests to pass through.

While other services like the Alibaba Cloud Security Center may provide broader security features and monitoring, they do not focus specifically on firewall capabilities aimed at protecting web applications. The Data Encryption Service primarily deals with protecting data at rest and in transit through encryption mechanisms, and the Container Service focuses on management and orchestration of containerized applications rather than direct firewall functionalities. Therefore, the Web Application Firewall stands out as the right service that directly aligns with firewall-related functionalities on Alibaba Cloud.
