Distributed denial-of-service attacks on public servers have recently become more serious. More are SYN Flood attacks, since the malicious attackers can easily exploit the TCP specification to generate traffic making public servers unavailable. To assure that network services will not be interrupted, we need faster and more accurate defense mechanisms against malicious traffic, especially SYN floods. But single point deffense (ex. firewalls) cannot work at the large distributed attacks.
In this paper, we introduce a distributed defense mechanism using overlay netwroks of TCP Proxies. This mechanism detects attacks near the victim servers and alert messages are sent via the overlay networks. And then TCP Proxies classify packets to the victim servers and blocks malicious traffic. The packets classified into legitimate traffic are protected by being sent via overlay networks. We simulate and verify our proposed method can effectively block malicious traffic and protect legitimate traffic. |
