Dynamic deep stateful firewall packet analysis model

Due to challenges of COVID -19 pandemic, network is widely used and more networkthreats are evolving, therefore, there is a need to improve network tools in order tocontrol threats. Stateful firewall is a network tool that build up packet filters by keepingrecord of packet passing through the network in a state table, so that when a newpacket arrives, the stateful firewall filtering mechanism first checks to determine whetherthe information is similar to the one in state table, in order to allow or blocked a packet.Although several stateful firewall models have been developed to filter network packets,there is no model that is able to filter the entire parts of a network packet which includethe header, trailer and payloads. In the stateful firewall models developed, mixedresearch methodology have been used. The models are developed in pythonprogramming language; an experimental research design is used, string matching andpattern matching algorithms are used in developing the models.
