En la presente tesina se realiza una descripción de la tecnología de Conmutación Multi-Protocolo mediante etiquetas usando una red privada virtual para la comunicación de una entidad empresarial. Se realizó una descripción de la tecnología MPLS con VPN mostrando sus cualidades, ventajas y desventajas, se promueve la esta tecnología a la red de comunicación de datos de la empresa tenga un performance y confidencialidad en los datos transmitidos, diseñando un esquema así como la infraestructura que podría ser usada en esta implementación, con características modulares las cuales permitirá a la empresa ir creciendo a la medida de que su tráfico o demanda de transporte vaya aumentando al igual que la integración de las demás extensiones se amerita el caso; para el diseño nos ayudaremos del programa de simulación “GNS3” el mismo que se hará un bosquejo de la configuración y modelo para la transmisión de sucursal a matriz y viceversa. This thesis is a description of MPLS VPN using a communication from the business entity. Was a description of MPLS VPN showing his qualities, advantages and disadvantages, promotes the introduction of this technology to the data communication network of the company to have a performance traffic and confidentiality of the data transmitted, designing scheme as well as the infrastructure that could be used in this implementation, modular features which allow the company to grow to the extent that their traffic and transport demand will increase as the integration of other extensions are merited case, to help us design simulation program "GNS3" the same to be made a sketch of the model configuration and transmission branch to parent and vice versa.

In today’s society, serious organizations need protection against both internal and external attacks. There are many different technologies available that organizations can incorporate into their organization in order to enhance security for their networking applications. Unfortunately, security is way to often considered as an afterthought and therefore implemented as an external part of the applications. This is usually performed by introducing general security models and technologies. However, an already developed, well structured and considered security approach – with proper implementation of security services and mechanisms – different security models can be used to apply security within the security perimeter of an organization. It can range from built into the application to the edge of a private network, e.g. an appliance. No matter the choice, the involved people must possess security expertise to deploy the proposed security models in this paper, that have the soul purpose to secure applications. By using the Recommendation X.800 as a comparison framework, the proposed models will be analyzed in detail and evaluated of how they provide the security services concerned in X.800. By reasoning about what security services that ought to be implemented in order to prevent or detect diverse security attacks, the organization needs to carry out a security plan and have a common understanding of the defined security policies. An interesting finding during our work was that, using a methodology that leads to low KLOC-values results in high security, though low KLOC-values and high security go hand-in-hand.
