SAFEFW: controle de conexões remotas

Abstract

The remote access protocols are used to enable a user to access a machine remotely. The most common protocols are SSH, RDP, RFB and Telnet. These protocols provide greater flexibility for users, allowing quick access to equipment without the need for physical proximity. However, their use cause some security issues. Among the issues raised there are: the occurrence of brute force attacks, difficulty in management connections and mechanisms that provide detailed information of all access made. To solve these problems, we propose a new architecture based on a central server responsible for managing all connections and for providing security mechanisms. The proposed architecture was implemented in a large network. The results show that it has solved the safety problems, and it is stable and robust.
