What security option is designed to help protect against DDoS attacks?

Alibaba Cloud Anti-DDoS Pro is specifically designed to defend against Distributed Denial of Service (DDoS) attacks, which can overwhelm a system with a flood of traffic, rendering it unavailable. This service provides advanced protection features that automatically detect and mitigate DDoS attacks in real-time. It utilizes a multi-layered security approach, which includes traffic scrubbing and anomaly detection, ensuring that legitimate traffic can flow while malicious requests are blocked.

The other options, while they contribute to overall security, serve different purposes. The Alibaba Cloud Firewall Service focuses on controlling and filtering incoming and outgoing network traffic based on predetermined security rules. Alibaba Cloud Security Center offers comprehensive security management, including threat detection and vulnerability assessment, but is not specialized specifically for DDoS protection. The Alibaba Cloud Intrusion Detection System aims to monitor network traffic for suspicious activity, but again, does not provide the same direct and specialized defense against DDoS attacks as Anti-DDoS Pro does.
