The firewall deployments have become a favorite research area within IT world. The design of framework and the algorithm of rule set can affect the overall performance of the filtering system. This review paper discusses some of the unique researches to build an effective and efficient filtering model. The application level and system level performance must work in efficient manner to build up a fast and accurate filtering process. The mechanism or how the packet is processed from being received at the physical layer or the network card until further processed by the application layer support software such as an IDS is highly influential for overall packet filtering infrastructure. © 2012 IEEE.
