Comparativo dos protocolos IPSec e SSL na utilização de VPNs corporativas

Abstract

The Internet has become a low-cost infrastructure, but it is an environment of unsafe communication. Virtual private networks (VPNs) are used by many organizations to provide secure and confidential communications over untrusted networks and are an economically viable option to meet this need. Uses combination of strong encryption and authentication technologies. The data is protected in the form of an encrypted tunnel to transmit over the internet, this tunnel connects two defined points. A VPN provides the end user with assurance of authenticity and confidentiality of the data packets. The objective of this work is to present the implementation of VPNs with the two main technologies currently used, the IPSec and SSL protocols. It was necessary to configure and implement some Internet and security protocols. In this work it is concluded that it is not possible to perform a fair comparison of performance due to the implementation methodology that was used in a virtual environment, but it serves the purpose of presenting the operation and the implementation of VPNs to make the data communication medium of the companies insurance. It is concluded that it is not possible to perform a performance and security comparison between VPNs due to the methodology used for the development of this work.
