Uma análise comparativa da segurança da informação em um ambiente de pequena empresa

Abstract

The objective of this research has been to perform a study, which is mainly focused in explaining how the small companies, with a low budget, are able to achieve a good security level. For that purpose we adopted the Survey method, which used, as its primary source, the collection of data together with the professionals who work with the security of information in different Brazilian cities. The researched solutions were divided in categories, and in order to obtain a better use of the collected data, tables were created based on mathematical formulas to relate those data specifying the solutions that achieved the best grades. After analyzing the collected data, the solutions achieved the main objective of the research. They were low cost solutions, with a good security level. In the Firewall category the Check Point solution stood out, obtaining high grades in all the analyzed items. In the Scanner of Vulnerability category, the Nessus software was the highlight. In the IDS category, the configuration difficulty and its cost, made its use practically not viable.
