website servers with a large amount of information that requires responses, consuming network bandwidth or system resources (such as CPU processing time and memory ), as a result, the network or system is overwhelmed to stop providing normal network services. The high CPU usage, a large number of UDP and ICMP data packets, the company's network symptoms are similar to the characteristics of UDP Flood attacks.
How can we find and completely solve the system vulnerabilities that cause UDP Flood a
