Utilização da VPN no cenário de teletrabalho

Abstract

This study comprehensively addresses the concept and characteristics of Virtual Private Networks (VPNs), highlighting the importance of their application in the context of teleworking. The work explains the fundamentals related to security in computer networks, highlighting the essential requirements for establishing secure communications and presenting the functioning of encryption algorithms. It is also highlighted that VPNs are widely adopted due to their cost-benefit ratio, and their operability in the internet environment is analyzed, with an emphasis on the Internet Security Protocol (IPsec). The present study shows how IPsec works, exploring its structure and its applicability in the teleworking scenario. To complement this, details are presented about the implementation of the VPN, showing the tests environment used to simulate teleworking. The simulation scenario involves configuring a client and a VPN server in a virtual machine, incorporating Domain Name System (DNS) and Active Directory services for VPN configuration on Windows Server.
