Designing the VPN with Top-Down to Improve Information Security

In this article, presents a systematic review of virtual private networks (VPNs) and their contribution to improving information security, with a particular focus on the Andia Consortium. It examines how VPN technology, through its ability to provide a secure channel for communication between devices, can protect organizations’ valuable digital data against cyber-attacks. Various types of VPN systems, their security strategies, advantages and disadvantages, and their dependence on different protocols and standards are discussed. Additionally, tunneling technology, a key technology in VPN implementation, is explored. Through this study, we seek to identify the benefits and limitations of using VPN to improve information security. This work aims to provide a deeper understanding of how VPNs can be designed from the top down to improve information security in organizations.
