Application Scenarios

CNAD Basic protects public IP addresses on Huawei Cloud only from DDoS attacks.

CNAD Basic devices are deployed at egresses of data centers. Figure 1 shows the network topology.

Figure 1 Network topology

The detection center monitors network access traffic based on security policies you configure. If an attack is detected, data is diverted to scrubbing devices for real-time defense. Abnormal traffic is cleaned, and normal traffic is forwarded.

Anti-DDoS provides 500 Mbit/s of mitigation capability against DDoS attacks for free. Traffic from the attacked public IP addresses will be routed to the black hole and the legitimate traffic will be discarded.
