Análise e simulação de VPN com IPSEC em roteadores CISCO

Abstract

The purpose of this monograph is to present and explain the necessary steps to configure the IPSec tunnel mode using Cisco routers to securely share access to a private network through the Internet. For businesses today, the need to share data between different branches is greater than ever. The internet provides an economical way and with a pre-existing infrastructure to accomplish this, but it has many security threats. The research presents theoretical concepts along with a simulated practical application in a real environment, demonstrating the practicality, functionality and the techniques used for the applicability of IPSEC in small networks in the current Internet using Cisco routers.
