摘要

In recent years, the number of users connected to the Internet has experienced a phenomenal growth. The security of systems and networks become essential. That is why the performance of Linux firewall and Berkeley Software Distribution (BSD) are of paramount importance in security systems and networks in all businesses. The following evaluates the firewall based tool that we have developed in Python and Scapy, which performs time measurements by serving packets traversing the firewall test. Several results were presented: the speed of the firewall under FreeBSD in terms of service time compared to the speed of the firewall under Linux as the number of rules increases;the speed of the filtering rule of a firewall stateless in terms of service time compared to the filtering rule of an active firewall gradually as the number of rules increases. Then, for care of simplicity, we have presented the queue M/M/1/K to model the performances of firewalls. The resulting model was validated using Simulink and mean squared error. The analytical model and Simulink of the firewalls are presented in the article.
