Best Practices for VPN Tunnel Encryption

Introduction

In modern cyber security environments, ensuring the robustness of encryption is important. Internet Key Exchange version 2 (IKEv2) is critical for establishing secure VPN tunnels. We recommend these Best Practices for VPN TunnelClosed An encrypted connection between two hosts using standard protocols (such as L2TP) to encrypt traffic going in and decrypt it coming out, creating an encapsulated network through which data can be safely shared as though on a physical private line. Encryption. To follow all of these Best Practices, all member gateways in the VPN CommunityClosed A named collection of VPN domains, each protected by a VPN gateway. must support all of these settings.
