능력 토큰을 이용한 SYN 범람 공격 방어 프레임워크

Alternative Abstract: Nowadays, Internet infrastructure has quickly grown up. Additionally, DDoS attacks have been serious threat on Internet infrastructure ever since Internet was established. These attacks block and limit legitimate user’s access links against the intended services. The methods of these attacks are consuming the network resources or remote victim’s resources by flooding packets on the network. A characteristic of DDoS attacks is that the flooded attack packets are source IP spoofed packets. Attacker even can manipulate all the fields of IP header. Consequently by using IP spoofing technique, attackers can flood spoofed IP packets on Internet that consume limited Internet resources. It is hard to filer these attack packets because it is also hard to identify normal packets and attacks packets. The SYN flooding attacks disturb TCP / IP 3-way handshaking between normal user and victim host. SYN flooding attacks use weakness of TCP/IP protocol. These attacks are easy to implement and efficient to disturb services between normal users and victim hosts. In this paper, we proposed framework to cope with flooding based DDoS attacks. In our method, the victims can survive from DDoS flooding based attacks.
