Proposta de interface para ensino de funcionamento interno de um Firewall

Abstract

Internet is an element of great importance to society today, with a trend of increasingly become indispensable for our people. One of the agents responsible for balance and organization of this network is the firewall. Encouraged over the past four years ministering such content in the disciplines of computer networks in the course of Information Systems, noted the difficulty on the part of students to abstract and visualize the events inside the firewall. This difficulty comes to understanding the inner workings of the firewall, how he carries himself on a list of control rules, what actions should be taken before each data packet passing through it. The objective of this study is to analyze the difficulties of teaching a firewall and propose the use of a software interface to improve the teaching of the subject. So I present a literature review concepts about raising signs, semiotics, interface design and human computer. This study led to the election of a list of qualities to be featured on the interface proposed in this paper. Then we present the basic operation of a firewall, describing the key skills of it's own, presenting a further analysis of management interfaces most commonly used firewall. Finally, I present a proposal for a rough interface through a learning environment conducive to teaching and learning of the subject taking into account the qualities then identified
