Distributed Denial of Service Attack Research Based on Proxy Servers

Denial of Service(DoS) attacks against the web server have many deficiencies such as unreasonable attack organization and obvious network traffic characteristics.Security measures such as SYN cookies are capable of effective server monitoring to defend against those attacks.This paper proposes a distributed denial of service attack technique based on proxy server.Sessions are built between the proxy server and the targeted web server,with service requests submitted to the web server.So the web server resources are consumed.Experiments indicate this techique performs well,with few anomalies in network traffic,which means good concealment.
