Estudo da aplicação da técnica de hardening nos servidores web do hospital de clínicas de Porto Alegre

This article presents a study to apply the technique of hardening, shielding of operating systems, in the web servers of Hospital de Clínicas of Porto Alegre - HCPA, with the purpose of increasing the security and in this way reducing the risks to the system. The work was done through a bibliographical research, seeking to obtain a script to follow, to identify and to fix fragile points in the security of a GNU / Linux system, used as a web server. To do this, the analysis tools and the hardenig techniques investigated were applied directly to the HCPA web server, presenting in the article the results obtained and the solutions performed. The research indicated several possible security threats to occur in newly installed systems, or in active systems that are poorly configured, also showing several techniques to mitigate such risks, as well as the possibility of auditing the system through techniques and tools that show where an administrator should work to improve security on GNU / Linux web systems.
