Study of Efficient Firewall Packet Filtering and Matching Algorithms
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 11
Abstract
for the network devices like firewall or IPsec, packet filtering is plays extremely significant role in high speed networks. Thus it is important that firewall policies should be optimized in order to make available the efficient security for high speed networks. There are many techniques presented by researchers for exploiting the distinctiveness of the filtering policies, however they do not consider the traffic behaviour in optimizing their search information structures. In this, recent new optimized packet filter and packet matching techniques for both stateless and stat full firewall are discussed. First Algorithm is presented using an objective of reduction in packet matching cost in all circumstances. Second algorithm is presented with an objective of low cost and less packet matching time. The performance of the algorithm is related to complexity of the firewall rule set and is compared to a substitute algorithm signifying that the algorithm here has improved the packet matching cost in all cases. Thus in short we present an algorithm which orders the rules in a firewall law set to finest suit the trends in the network traffic (as given by a recent network trace file) and therefore reduce the potential number of packet-rule matches. Whereas in second investigated algorithm we consider a classical algorithm that we personalized to the firewall domain. Resultant algorithm is known as “Geometric Efficient Matching” (GEM).The GEM algorithm enjoys a logarithmic matching time performance.
