DoS protection for a Pragmatic Multiservice Network Based on Programmable Networks
Proceedings of First International IFIP TC6 Conference, AN 2006, Paris, France, September 27-29, 2006.We propose a scenario of a multiservice network, based on pragmatic
ideas of programmable networks. Active routers are capable of processing both
active and legacy packets. This scenario is vulnerable to a Denial of Service attack,
which consists in inserting false legacy packets into active routers. We
propose a mechanism for detecting the injection of fake legacy packets into active
routers. This mechanism consists in exchanging accounting information on
the traffic between neighboring active routers. The exchange of accounting information
must be carried out in a secure way using secure active packets. The
proposed mechanism is sensitive to the loss of packets. To deal with this problem
some improvements in the mechanism has been proposed. An important issue
is the procedure for discharging packets when an attack has been detected.
We propose an easy and efficient mechanism that would be improved in future
work.Publicad
