Anti-DDoS supports blocking the source traffic accessing Anti-DDoS instances based on specified protocols, such as ICMP, TCP, and UDP. Requests over the specified protocols are blocked directly.
UDP is a connectionless protocol, which is vulnerable to attacks. It's recommended to block UDP requests unless necessary.
Directions
1. Log in to the Anti-DDoS console and click DDoS Protection on the left sidebar.
2. Select an Anti-DDoS instance ID in the list on the left, such as "bgp-00xxxxxx".
