OPENVPN AND ITS APPLICATION IN A BUSINESS ENVIRONMENT

Abstract

Virtual Private Networks are essential to ensure secure communication on public networks. This study presents explanations of the security protocols used in VPNs and their application in network environments. Initially, the document defines VPNs and their relevance in protecting data transmission on vulnerable networks. Next, the evolution of this technology is explored, focusing on the evolution of traditional IPSec and SSL/TLS protocols to more current versions. VPN security protocols are evaluated, analyzing IPSec, SSL/TLS, SHA-256 considering their security characteristics, performance and suitability for different scenarios. Furthermore, the applications of VPNs in current contexts are discussed, including remote access and connectivity between branches. The study also addresses the challenges and considerations in the process of deploying and managing VPNs in complex networks. Finally, the importance of VPNs is highlighted to ensure secure communications in current infrastructures.
