Which advanced feature is included in the Anti-DDoS Pro service?

The Anti-DDoS Pro service includes protocol packet filtering as an advanced feature, which is a crucial aspect of protecting against Distributed Denial of Service (DDoS) attacks. This feature allows the system to inspect and filter packets based on the protocols they use, effectively identifying and blocking malicious traffic aimed at overwhelming the targeted network resources.

Protocol packet filtering provides a layer of security by ensuring that only legitimate traffic is allowed through while dropping packets that may come from known malicious sources or exhibit suspicious behavior. This proactive approach helps maintain the availability and performance of services, preserving uptime even during an attack. The capability to filter at the protocol level is essential in modern security architectures, where attackers continuously evolve their tactics.

While the other options may seem relevant to network management and security, they do not specifically pertain to the core functionality of the Anti-DDoS Pro service designed to mitigate DDoS attacks.
