Recently, DNS amplification attacks are occurring frequently.
This attack is one of DDoS attacks.
Thus, a large-scale attack may cause congestion even in a provider network.
As the solution, we have proposed a distributive virtual firewall scheme for a provider network.
In this scheme, attack traffic from reflector to victim can be blocked.
However, legitimate traffic from reflector to victim may be also blocked.
In order to solve this problem, in this paper, we propose a cooperation scheme of firewall function and address translation function.
In this scheme, address translation is applied to legitimate IP packets from reflector to victim
when attack IP packets are sent from reflector to victim.
This enables easy separation between legitimate traffic and attack traffic
and thus excessive blocking of legitimate traffic can be avoided.
On the other hand, address translation may increase end-to-end packet forwarding delay.
Therefore we evaluated it using a prototype system.
Our evaluation results showed that increased delay was less than 13 percent.
Consequently, the proposed scheme seems effective solution as a countermeasure against DNS amplifying attacks that aim disturbing legitimate communication service. |
