Implementação de um gateway de segurança com sistema operacional dedicado

Abstract

In this paper we implemented a case study of a security gateway based on the OpenBSD operating system installation with IDS / IPS snort, firewall, VPN, load balance and development of automation scripts in order to make it optimized and specialized in protecting computer networks. Aspects of information security such as: project costs involved; implementation difficulties; analysis methodology. There were issues relating to types of cyber threats, projects focused on information security evaluation methodology of security of computer networks and best practices settings. Searches were made of the emergence of viruses, hackers and systems defenses as packet filter, snort and OpenBSD project.
