Estudio y diseño de un sistema de comunicaciones unificadas VoIP basado en Elastix con seguridad perimetral.

Abstract

In this project, an analysis of the threats faced by a VoIP network based on Elastix will be carried out and how it can provide protection and reliability to its operation; The configuration of a VoIP network with different connections of telephone hosts and computer equipment will be described; The installation of an Elastix IP telephone exchange and its operation in the VoIP network will be described; perimeter protection of the network will be established by means of a firewall. In the network operating environment, different forms of attacks on the Elastix telephone exchange will be analyzed; The configuration of protection policies in the firewall will be analyzed and described in such a way as to provide protection against external addresses to surround the external perimeter of the network; on the other hand, it is possible to define the protection of the control panel for attacks from the internal network, that is to say protection in the internal perimeter.
